The power supply module is a switching mode power supply unit that converts the power supply voltage to 24 volts DC and is suitable for both non-redundant and redundant applications where the diode-voting unit SS823 or SS832 is required. It complies with the relevant standards such as EN 50178, EN 61131-2 and UL 508, has over current (current limiting) and over voltage (OVP) protection, and also provides a soft start function that does not trigger fuses or ground fault circuit breakers when powered on.
