Abstract:
A system and method for providing a protective extra low voltage power supply in an elevator system (2) is disclosed. The power supply system (10) may include a switch mode power supply (12) configured to provide an output voltage, a first voltage monitor (18) and a second voltage monitor (20). Each of the first voltage monitor (18) and the second voltage monitor (20) may be configured to receive the output voltage and determine an over-voltage condition at the switch mode power supply (12).
