Siemens (PSC-12M) Main-Power Supply Charger S54430-C26-A1
The Siemens 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’.
Each Model PSC-12M provides 12 Amps of Desigo Modular system output power @ 24VDC. Two (2) separate power-output terminals are available: one (1) power limited with 4A max @ 24VDC capacity, as well as one (1) non-power limited with 12A max @24VDC capacity (the total not to exceed 12A). Model PSC-12M also provides two (2) connection points for the 60-pin power / data bus. Additionally, the 24VDC outputs found a Model PSC-12M provide auto-resettable current protection circuits for overload and short-circuit panel conditions.
In event of a Desigo Modular system power failure, backup batteries are used. Though when main-system power is active, Model PSC-12M is able to charge back-up batteries that carry the following current: up to 15AH | 31AH | 75AH and up to 100AH batteries. The battery sizes that are used in a given Desigo Modular panel are entered into the custom-configuration software tool, Zeus-D, and the power charger (Model PSC-12M) has three (3) modes – dependent upon condition: Bulk (full) Charge State | Trickle Charge State and Float (maintenance) State. Model PSC-12M subsequently is able to monitor the condition of the batteries automatically, determining which of the charging modes to activate.
