SERIES DESCRIPTION
The Hitachi RCU Series Regenerative Converter Units recover braking energy from inverters and return it to the power supply, improving overall system efficiency and reducing heat loss. Designed for 200V and 400V inverter systems, they integrate seamlessly with Hitachi drives for enhanced reliability and energy savings.
Features
- Energy-saving regeneration returning braking energy to the grid
- High regenerative torque capability: 150% (30s), 100% (100s), 80% continuous
- Protection against over-current, over-voltage, overload, overheating, and phase imbalance
- Healthy/fault relay outputs and emergency-stop input
- Compact wall or panel mounting design with vertical orientation
- Simple DC-link connection to inverter (P/N terminals)
- Indoor use: −10°C to +40°C, up to 90% humidity (non-condensing)
- PWM current control for smooth regeneration and reduced harmonics
- Built-in safety and fault diagnostics with LED indication
