SIGMA IPM-RLA REV1.2 MMR Elevator IGBT Drive Board with PM50RLA120 / PM75RLA120 Core for Ultra-Low Stray-Inductance and On-Board Gate-Drive Redundancy
SIGMA IPM-RLA REV1.2 MMR Elevator IGBT Drive Board (PM50/75RLA120 Core)
The SIGMA IPM-RLA REV1.2 drive board serves as the central component of the MMR-series elevator inverter. Engineered around the intelligent PM50RLA120 / PM75RLA120 IGBT module, this board provides ultra-low stray-inductance power paths and integrated gate-drive redundancy, significantly reducing dynamic losses and preventing jitter-induced shutdowns. Designed as a plug-and-play solution compatible with original LG-Sigma harnesses, it supports elevator capacities ranging from 6-person to 30-person lifts without requiring hardware modifications.
Key Advantages
- 100% drop-in replacement—no cabinet wiring modifications required
- Conformal-coated PCB ensures reliable operation in 60°C ambient conditions
- 1-year warranty with CE & RoHS compliance certification
