Reliance HR2000 BLA-04 AC Servo Drive Module

Reliance HR2000 BLA-04 AC Servo Drive Module, model 3RA2001, is a 1 HP brushless AC servo drive in the HR2000 family. It accepts 180 VAC input and delivers up to 4 A continuous current to a compatible servo motor, enabling precise torque and velocity control for single-axis motion systems. The BLA-04 option code denotes a specific wiring/configuration within Reliance Electric’s HR2000 line, while the 3RA2001 designation identifies the servo controller module itself. The HR2000 High Performance Drives are designed for fast dynamic response and accurate positioning in automation tasks, such as tooling, packaging, and light robotics. As the motion controller, this module interprets commanded trajectories and encoder feedback to produce smooth, precise motor drive signals, supporting servo applications that require reliable, compact 1 HP performance at a relatively low-voltage 180 VAC supply.
