Siemens 6EP4548-7XB00-3AX0 Chopper module SITOP CHO1400, 1 kW, brake chopper, DC 24 V, DC 48 V

SITOP CHO1400 24/48V chopper module 1kW DC 24-28V | 48V - 56V with monitoring interface The SITOP CHO1400 chopper module is the ideal complement for all 24 and 48 V power supplies to provide additional protection against failure of the supply. The chopper module is connected in parallel to the output of a 24 V or 48 V power supply and serves as surge protection. If the voltage exceeds a response threshold due to regenerative feedback (Ue +2V or +4V), the chopper module limits the voltage to the response threshold by converting the recovered energy into heat via internal resistors. The chopper module can take up a maximum of approx. 1 kW of power and approx. 1.8 kWs of energy. When this energy is reached, the module deactivates itself and waits for a specified cooling time until it is ready for use again. Two chopper modules can be connected in parallel to increase power.
