Power supply PSU 24 V-1

581726 | Power supply PSU 24 V-1

The PSU 24V-1 power supply is designed to work with the INTEVIO PA/VA System. It acts as a battery charger and control device for 24 VDC external back up batteries in accordance with EN 54-4+A1+A2 standards.

The front panel includes LED indicators, control push button and USB socket, allowing control and test of power supply operating parameters.

All connections are located at the rear of the unit, which has two confi guration options: all 6 outputs providing the same current or 2 of the 6 with increased current-carrying capacity.

The power supply meets all requirements of the Regulation of the European Parliament and of the Council of Europe No. 305/2011 of 9 March 2011 [CPR]. It holds certifi cate of constancy of parameters CNBOP No. 1438-CPR-0496.
