Power Distribution
SE Series – Central Mains Supply
- Voltage up to 3 x 400 V
- Current up to 32 A
- Various mains configurations
- Emergency stop function
Features
H&H power distribution units are designed for the construction of comprehensive test facilities in connection with electronic loads. They serve as a central mains switch with emergency stop function, whereby the emergency stop can also be integrated into a higher-level emergency stop system. Each circuit is individually fused. Some of the devices are equipped with their own residual current circuit breaker. An integrated DC power supply extends the flexibility.
