FAQ

The unit is designed for a 400 VAC input. Given the typical industrial application, it is likely intended for connection between two phases of a three-phase system, but you should always verify the connection scheme based on the machine it was removed from or consult an electrical expert.

As a linear power supply with a large transformer and capacitor, the output is smoothed and filtered DC. However, it may be an unregulated supply, meaning the voltage could vary slightly with input voltage and load. For highly sensitive electronics, you should verify if its voltage stability meets your requirements.

The PKZM0-10 is a motor protection circuit breaker. Its inclusion suggests this power supply was likely used to power a DC motor or a system with inductive loads, providing both overcurrent protection and a manual disconnect function.
