PM50RL1A120

Overview

The PM50RL1A120 is a 7-pack Intelligent Power Module (IPM) from the L1-series, manufactured by Powerex Inc. It integrates a three-phase IGBT inverter and a brake rectifier within a single insulated package. The module features a continuous collector current rating of 50 Amperes and a collector-emitter blocking voltage of 1200 Volts. Designed for AC400V line applications, it utilizes screw-type main terminals and pin-type control interfaces.

Feature Summary

• Integrates three-phase inverter and brake rectifier circuits
• Includes built-in protection functions such as overcurrent and short-circuit detection
• Utilizes high-speed, low-loss IGBT technology with optimized gate drive circuitry

Applications

• General purpose inverters for AC400V lines
• Servo motor controls
• Industrial motor drives

Procurement Notes

Verify the specific revision level against the manufacturer's latest documentation to ensure compatibility with interface requirements. Confirm that the screw-type main terminal connection method aligns with the system design specifications before procurement.

Selection Notes

Select this module based on thermal calculations for the intended operating conditions. Ensure the heat sink flatness and thermal grease application meet the specified guidelines to maintain optimal junction-to-case thermal resistance and device reliability.

Part Context

This component belongs to the Mitsubishi Electric L1-series IPM family, distributed by Powerex Inc. It represents a generation of intelligent power modules combining high-power IGBTs with advanced control and protection circuits to reduce system size and cost.

Replacement Considerations

Compatible substitutes include PM50RL1B120 and PM50CL1A120. Verify terminal configuration differences, as the RL1B variant uses pin-type main terminals while the CL1A lacks the brake rectifier section.
