Power Supplies
BP.
 
     Switching Power Supply BP is designed to supply the equipment in security, fire systems, telemetry systems, such systems and any other equipment.

      BP is used both separately and as part of the equipment (consoles, repeaters, etc.).

 PS provides:

- convert AC voltage to 220 V:

       a) 13.5 V DC with a maximum load current of 3 A;

       b) 5 V DC with a maximum load current of 0.5 A;
- charge battery (capacity < 7 A/h);
- powered by an external battery;
- when working in the station (console / repeater)*:

       c) control voltage 220 ​​V, 13.5 V and 5V;

       d) control of temperature of station;

       e) enables / disables the internal fan;

       f) testing of voltage of connected battery and its capacity.
