The PS1A-LCK module is supplied from 18 VAC voltage which converts into DC voltage and delivers to 2 supply outputs.
The first output, 13.8 V/1.0 A rated, is dedicated to supply door lock and other access door equipment (e.g. door bell). The second output, 13.8 V/0.2 A rated, is dedicated to supply access readers. The 1.0 A output can be controlled by ON/OFF signal applied to module’s input. Both outputs have overload protection.
The PS1A-LCK has DC back-up supply input which is used for connection of reserve power source, usually battery, when AC voltage is absent. The lack of AC voltage is signalled on dedicated transistor output.
The PS1A-LCK is mainly used when existing build-in power source on access controlled or expander is not capable to supply second access door and the supplementary power source is necessary.
