PMU-27V155WCBA

PMU-27V155WCBA is a PMU panel mount power supply, with integrated DC UPS function, prevents end-product downtime for the customer in the event of failure/disruption or unexpected loss of input AC power. It is suitable for security system, access control, automatic doors, alarm system, and other similar products. In addition to having overvoltage, overload, over temperature, deep battery discharge, and reverse battery polarity protections on the main output, there are also short circuit and overload protections when operating in the buffering mode. The PMU design meets worldwide safety approvals, certified to Class B radiated and conducted emission requirements, and is also available in an L Frame platform for different application needs. It includes overvoltage, overcurrent, overload, short circuit protection. Certified according to IEC/EN/UL 62368-1. Application includes buildings, machine, process, factory automation.
