The Model PSC-12M Power-Supply Charger is a high-current power supply that provides a Desigo Fire Safety Modular (Desigo Modular) panel with primary, regulated 24VDC power to operate at 12 Amps (`Alarm’ mode) / 5 Amps (`Standby’). With its built-in battery charger – capable of charging up to 100AH batteries, Model PSC12M is an addressable-intelligent, microprocessor-controlled power module that communicates its status to the Desigo Modular Operator Interface (OI), Model FCM2041-U2. Moreover, the panel’s OI is able to query the status of the power supply to obtain data regarding system-charging current | terminal-loading information | ground fault-conditions and more.

Model PSC-12M is a universal power supply, accepting AC power-input levels from 120VAC – 240VAC @ 50 / 60Hz. No special configuration is required: Model PSC-12M is designed to operate across these AC input ranges. A 60-pin connector is used for communication between a Model PSC-12M charger and other system cards and modules. The communication transmission (of which has variables of 6.2VDC and 24VDC), is referred as `back-plane current’.
