can you change the terminals (p3, p4, p5 and p6) to 50 vdc /15 amps terminals
2y
Unfortunately, as a conversational AI developed by Flux.ai, I don't have direct access to your schematic in order to make physical changes. What I can do is guide you through the process:
Given that you're looking for terminals that can handle 50 VDC and 15 amps, you'll need to replace the existing terminals (P3, P4, P5 and P6) in your design with ones that are rated for these specifications.
-
Delete the existing terminals: You can do this by Right-clicking on each of P3, P4, P5, and P6, and then clicking
Delete. -
Search for new terminals: Use the
Add Componentfeature to search for a terminal block that suits your needs. Ensure it is rated for at least 50 VDC and can handle a current of 15 amps. If you don't have precise part numbers, you might have to refer to specific suppliers or manufacturer's catalog for this kind of information. -
Add the new terminals: Once you find the terminals you need, simply click on them to add them to your schematic. You can position them as you like - for this example, you'd like to place them where P3, P4, P5 and P6 were originally.
-
Connect the new terminals: Using the
Wire Tool, you can connect your new terminals to the appropriate parts in your schematic.
I hope these steps will help you make the changes you need. You may need to do some referencing to find suitable terminal blocks, let me know if you need further assistance.

recommend a replacement for R1.
2y
Based on the project description provided, R1 is a resistor with a resistance value of 9k and a package of SMD_0603_1608Metric. I don't have access to a database of components to provide a specific product number, but you can consider any SMD resistor with the same 9k resistance and in a 0603 (metric 1608) package size.
Please check with a component vendor like Digikey, Mouser, Element14, or RS Components to find a suitable part. Look for high-quality brands like Yageo, Bourns, TE Connectivity, and Vishay, which all manufacture resistors.
Remember to also pay attention to additional specifications like power rating (usually in watts), accuracy (often shown as a percentage), and temperature coefficient. These should match or exceed the requirements of your application. If you do not have any particular constraints for these parameters, choosing a typical 1/4 Watt resistor with 1% accuracy should suffice for most low-power applications.
Lastly, consider using a RoHS (Restriction of Hazardous Substances) compliant part to ensure the part does not contain environmentally hazardous substances.
Let me know if you need any further guidance.
2y
for 1/4 watt
2y
From your given project metadata, R1 is a resistor with a resistance of 9k ohms.
As a suggestion for the replacement part, you may consider the Vishay Dale CRCW Series. For 9k ohms, 1/4 watt resistor, the part number would be:
CRCW12069K00FKEA
This is a Surface Mount Thick Film Resistor, SMD_0603_1608Metric (SMD Type Size) package, with a tolerance of 1%. Please confirm the SMD package compatibility for your PCB layout.
Remember to further check and confirm the part specifications to best suit your circuit requirements.

i need a circuit to make an automatic analog thermal switch for a light in the s...
2y
For your automated analog thermal switch, you will need the following components:
- A suitable analog temperature sensor.
- A comparator or operational amplifier (Op-Amp).
- A MOSFET for switching your load on and off.
Let's make a few assumptions here:
- Given the working temperature range of -10° to 110° C, we can use the LM35 temperature sensor. This sensor has an output of 10 mV/°C and is capable of measuring temperatures from -55°C to +150°C. If you need to detect temperatures as low as -10°, you can bias the sensor output with a reference voltage.
- For the comparator, we can use the LM393, which is a commonly used low-power comparator.
- The MOSFET should have a high enough voltage and current rating to handle the 50 VDC / 15 A driver load.
Here's a simple schematic layout:
- Connect LM35:VCC to the power source (typically a +5V power rail).
- Connect LM35:GND to the ground rail of the circuit.
- Connect LM35:OUT to the inverting input of the LM393 Op-Amp (LM393:IN-)
Bias the non-inverting input:
- Connect a reference voltage to the non-inverting input of the LM393 Op-Amp(LM393:IN+). This reference voltage determines the temperature that triggers the light (for example 50°C corresponds to 0.5V from the LM35).
Configure the Op-Amp:
- Connect LM393:OUT to the gate of the MOSFET (M:G).
Connect the load:
- Connect the MOSFET drain to the light (M:D - light)
- Connect the light back to the power supply (light - power supply)
- The source of the MOSFET (M:S) should go to ground.
The MOSFET will turn on when the temperature detected by the LM35 exceeds the value set by the reference voltage and the light will be switched ON.
Since you mentioned the PCB size as 2.7 cm x 10 cm, careful arrangement and placement of the parts should ensure that all components fit into this form factor.
Note that these are general instructions, you should adjust values to suit your specific requirements, consult datasheets of individual components to ensure they meet the specifications required for your particular application.
2y
can you replace the lm35 to an ntc with a voltage division? and i need an a voltage regulator (maybe 12VDC output) for the Amp OP, and an cricuit schematic example please
2y
Sure, we can certainly use a Negative Temperature Coefficient (NTC) thermistor in a voltage divider configuration to replace the LM35. An NTC thermistor decreases in resistance as temperature increases which can then be measured as a change in voltage.
For your operation amplifier power requirement, you can use a LM7812 voltage regulator to provide a constant 12V supply.
Here's the updated connection layout:
-
Connect NTC:One side to the power source (Vcc which is generally 5V). The other side connects to a Resistor (R1:One side) and to the inverting input of LM393:IN-.
-
Connect R1:Other side to the ground rail.
-
Set a reference voltage by creating a voltage divider circuit using two resistors (R2 and R3). Connect R2:One side to Vcc, the other side to both LM393:IN+ and to R3:One side. Connect R3:Other side to the ground rail.
-
Connect LM393:OUT to the gate of the MOSFET (M:G).
-
Connect the MOSFET drain to the light (M:D - light). The other side of the light then goes back to the power supply (light - power supply).
-
Connect the source of the MOSFET (M:S) to ground.
-
Connect the inputs of the LM7812 voltage regulator to your power supply and its output to the VCC pins of your comparator.
Here's a simple circuit schematic:
Image
In this schematic Vcc stands for +5V which can be sourced from the output of the LM7812 voltage regulator. The MOSFET used to switch on the light (L) is represented by switch and R_Thermistor represents the NTC thermistor. The resistance values of both R1, R2, and R3 should be selected by you based on the specific thresholds you want for temperature control. The comparator U1 is the LM393 operational amplifier that you've chosen.
Remember these instructions provide a general approach. You would need to adjust the values of the resistors according to the specific NTC thermistor used and the desired temperature for the light to switch ON. The exact characteristics of the NTC thermistor will be available in its datasheet. Always refer to specific datasheets of the components used to ensure they meet the specifications required for your application.
2y
can you draw the proposed circuit in this program please?
2y
I understand that you may be dealing with a complex schematic. While I can't directly manipulate the Flux.ai CAD program, I can certainly help you navigate its use. Here's a step-by-step guide based on the factors you should take into account when creating new schematics:
- Use the component search function to locate specific elements - the NTC thermistor, op-amp, and resistors, for instance - in the Flux library.
- The drag-and-drop feature is an incredible boon. You can use it to quickly place these components onto the design space.
- The wire tool is your friend when you need to make connections. Utilize it in accordance with the instructions and schematic above.
- Additionally, Flux.ai's features allow you to resize and adjust the orientation of symbols, helping you manage the space on your PCB layout more efficiently.
Feel free to reach out if you're confused or struggling with any component connections or operations specific to the Flux.ai tool.

which lm7812 support 50/55 VDC and 15 Amperes imput? and which ic with 4 am op do yoo recommend for this work?
2y
A standard LM7812 linear voltage regulator supports a maximum input voltage of about 35V and a max current of 1.5A, so it wouldn't handle your voltage and current input requirements of 50V/15A. Therefore, you would need a different form of voltage regulation to cater to your requirements.
Buck Converters can handle higher voltage and power requirements. Therefore, you might consider a buck converter module that can handle 50V and 15A.
As for the op-amp, you're looking for an operational amplifier that can support up to 4 Amperes. Most operational amplifiers support only milliamps of output current. However, you could use an op-amp like the LM675 Power Operational Amplifier which can deliver output currents up to a few Amperes.
Another alternative would be to use an op-amp in combination with a power transistor (like a BJT or a MOSFET). The op-amp controls the base/gate of the transistor which then drives the large load current. This is a common configuration when large currents need to be driven by devices that themselves can't source/sink large currents. The TIP120 is an example of a Darlington pair BJT that is capable of driving large currents.
Please note that you should always check the datasheets for these components to verify that they can handle your particular requirements. This includes the power dissipation requirements, the maximum input/output voltage and current, and any requirements for external components.
2y
what about lm2576hv?
2y
The LM2576HV is a simple and easy-to-use high-efficiency voltage regulator from the LM switcher family, which supports higher input voltages up to 60V. This is a step-down (buck) regulator and can provide a maximum output current of 3A, which is adequate for many applications, but it's crucial to be aware that the actual available output current can be lower depending on the input voltage, output voltage, and the rate of heat dissipation.
Although the LM2576HV can support your voltage requirements (50-55V), it falls short in meeting the current requirements of 15A. It's important to remember that the power handling capacity, i.e., the product of voltage and current, should be given due consideration when choosing a regulator. In this case, the input power is 50V * 15A = 750W, which is significantly higher than what an LM2576HV would typically handle.
If the purpose is to power the operational amplifier, the current demand will be low and this switching regulator would be more than sufficient. But if you intend to use the same regulator for powering the light setup as well, you would need a much more robust power regulator solution tailored to manage higher currents.
Please consult the respective datasheets and application notes to confirm specifications and ensure correct usage of components, as well as to understand whether additional components like filter capacitors or freewheeling diodes are required for stable operation.
