Description and Operation
1.1
Purpose
1.1.1
MP 24/12V DC-DC Power Converter Module (hereinafter referred to as the MP) is designed
to supply power to equipment of fire and intrusion alarm systems that require 12 V dc.
1.1.2
MP is intended for round-the-clock operation with specified output parameters when
cooperating with RIP-24 battery backed power supplies. The actual list of RIP-24 can be found at
http://bolid.ru/production/reserve/rip/
.
1.1.3
The design of the MP doesn’t imply operating it in ex-hazardous and flammable premises.
1.1.4
The MP provides protection against short circuit failures with recovering output voltage
automatically after repairing the failures.
1.1.5
The MP provides protection against reverse polarity of input voltage with further restoration
of performance.
