| Parameter Category | English Specification & Notes |
|---|---|
| Part Number Type | Non-catalog service/sub-assembly code; used for repair, replacement, and internal lifecycle tracking only |
| Core Board Function | IGBT gate signal generation/amplification, real-time power module status monitoring (current/temperature), overcurrent/overvoltage/overtemperature protection triggering, synchronization with main control board |
| Parent Drive Compatibility | Exclusively for PowerFlex 700/700S series VFDs (480V/690V AC 3-phase, medium-to-high power ratings); no cross-compatibility with PowerFlex 753/755 series |
| Public Spec Availability | No open-access electrical (gate drive voltage/current), thermal, or communication parameters. Exact specs are tied to the parent drive’s full model number, power rating, and firmware version |
| Reference Benchmark (PF700 Standard Gate Driver Board) | Gate Drive Voltage: ±15V DC; Max Gate Current per Channel: 5–6A; Isolation Voltage: 2500V AC (rms); Operating Temperature: 0°C to 55°C (Non-condensing, RH 10%–90%); Certifications: UL 508C, CE, RoHS |
| Spec Retrieval Steps | 1. Check the board’s silkscreen for official catalog P/Ns (e.g., 2094-xxx, 22A-xxx) or revision codes.
