| Parameter Category | English Specification & Notes |
|---|---|
| Part Number Classification | Non-catalog service/sub-assembly code; used solely for repair, replacement, and component lifecycle tracking in Rockwell’s internal service database |
| Core Board Function | IGBT gate signal generation & amplification, real-time power module status monitoring, overcurrent/overvoltage/overtemperature protection trigger, power conversion synchronization with drive main control board |
| Parent Drive Compatibility | Exclusively matched with PowerFlex 753/755 series VFDs (480V/690V AC 3-phase voltage ratings); no cross-compatibility with PowerFlex 70/700/700S series |
| Public Specification Availability | No open-access electrical (gate drive voltage/current), thermal, or communication parameters. Precise specs are bound to the parent drive’s full model number, power rating, and firmware version |
| Reference Benchmark (PF755 Standard IGBT Gate Driver Board) | Gate Drive Voltage: ±15V DC; Max Gate Current per Channel: 6A; Isolation Voltage: 2500V AC (rms); Operating Temperature Range: 0°C to 55°C (Non-condensing, RH 10%–90%); Certifications: UL 508C, CE, RoHS |
| Spec Retrieval & Verification Steps | 1. Inspect the board’s silkscreen for official Rockwell catalog P/Ns (e.g., 22A-xxx, 2094-xxx) or revision codes.
