Reliance 5RD0400 Converter

The Reliance 5RD0400 Converter is a 400-watt HR500 converter in the Reliance Electric/Reliance servo-drive family. This model is documented as 5RD0400 – HR500 CONVERTER, a part of the HR500 High-Performance Drives line used to power and control servo motors in automated equipment. A closely related variant, the 5RD0401, is described as a 400W HR500 Converter with encoder power supply, indicating flexible servo-encoder options for closed-loop operation. The HR500 family comprises servo drives designed for precise motion control, and the 5RD0400 designation identifies a converter within that ecosystem. Availability and identification of 5RD0400 appear in multiple distributor catalogs and listings, including EU Automation and Relectric, reflecting its role as a genuine Reliance Electric/Reliance servo-drive component in legacy automation inventories. In practice, this converter would be integrated in a servo-axis configuration to deliver conditioned power and amplification to a servo motor, supporting typical tasks in automation such as positioning, speed regulation, and torque control consistent with HR500-compatible motors and systems.
