Description:

This 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. The power supply will switch to battery operation (batteries not included) without interruption to increase the operational reliability of the critical mission. The TTL compatible monitoring signals for AC OK, DC OK and Battery Low will alert the user in the event of a failure. This convection-cooled single phase power supply has a wide operating temperature range from -20˚C to + 70˚C and 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 (battery discharging) 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.
