The MPL PMU-13V155WCCA is a panel mount power supply with an integrated DC UPS function that provides uninterrupted operation when mains AC power is lost or disrupted. It switches to battery operation (batteries not included) with zero switchover time, ensuring continuous supply to critical loads such as security systems, access control, automatic doors, and alarm panels.

Convection-cooled with no fan, it operates across a wide temperature range of -20°C to +70°C. TTL-compatible monitoring signals for AC OK, DC OK, and Battery Low allow integration with external alarm or supervisory circuits. The unit is certified to IEC/EN/UL 62368-1 and meets Class B radiated and conducted emission requirements per IEC/EN 61000-3-2 Class A.
