    Able Rose Carbonite Freezer

    Able Rose Carbonite Freezer thumbnail
    4‑Layer 100×60 mm PCB – Buck wiring and power nets verified (D3 to U7:VSW/GND, U7:FB to 3V3), IC power rails checked, BOM cleaned (duplicate L5 removed, MPNs standardized, mechanical holes excluded), ERC/DRC re-checked, BOM regenerated, UL 61010 isolation corridor annotations preserved, design BuildReady for manufacturing.

    Properties

    true

    Add copper heat-spreader islands and via-stitch regions around the buck cluster (U7, D3, output capacitor), and specify wide copper pours on VIN and 3V3 domains.

    BuildReady

    Reserve a routed copper-free corridor for CT front-end isolation; isolator remains on the barrier. Slots/keep-outs to be implemented in layout phase.

    100

    Human to implement UL 61010 creepage/clearance keep-outs and any required board slots/cutouts around high-voltage / mains-referenced circuits and isolation barriers (e.g., CT and AMC1301 channels) during final mechanical/layout review.

    Energy

    DIN-rail ground fault and liquid detection interrupter (GFLI) module for retrofitting 24 VDC data-center CDU/PDU systems, providing fault sensing (CT and moisture), MCU-based control, RS-485 communications, and relay output via terminal I/O. BOM regenerated after LED, buck, and moisture front-end updates.
