The redundant module RED00202 is designed for applications from 0Vdc to 125Vdc. DC-outputs from N+1 power supply units will be decoupled (equal power supplies and output voltages are recommended). If a breakdown occurs to one of the connected power supply modules, the other one will take over with no voltage drop to the system. While normal operation the load will be partitioned equal to each of the connected power supplies. The RED00202 power good relay features continuous control over the conditions of the connected power supplies. If one power supply fails the relay indicates that the remaining power supply takes over. The drop out voltage Vu can be adjusted via the control potentiometer. The DC-Input of the RED00202 corresponds to the output voltage of the power supplies installed. The GND-Input of the RED00202 is evident for the own supply only. The voltage drop between DC-input and DC-output is 500mV.
