SERIES DESCRIPTION
The Hitachi RCU Series regenerative converter units provide efficient power recovery by returning regenerative energy from the inverter’s DC-bus back to the AC line, reducing overall energy consumption and braking resistor heat losses.
The RCU-2015 model is designed for 200 V-class inverters up to 15 kW (20 HP), offering compact size, reliable thermal design, and multiple protection functions for safe regenerative operation.
Features
- Compact 200 V-class unit for 15 kW (20 HP) inverters (KE3 frame)
- Regenerative power feedback to AC mains to improve efficiency
- Built-in overcurrent, overvoltage and thermal protection circuits
- PWM current control for stable regeneration under variable loads
- 25 % ED duty cycle for cyclic energy recovery applications
