MSRK series

To be able to install PSU module in the Intrusion Detection Systems or Access Control
systems, it must be placed in enclosure with an appropriate design and, in order to obtain
certificate, supplementary tests must be commissioned for compliance with EN50131-6: 2017
or EN60839-11: 2013 standards in notified laboratory.
The power supply module should be configured to work in intruder alarm systems or
access control, depending on application. For this purpose, appropriate charging current should
be selected (taking into account battery capacity and required charging time).
