UPS

  D48-12

UPS D48-12 is intended for providing of assured trouble-free feed of radio equipments  

 on telephone exchanges by the DC-voltage 48V.
        D48-12 provid the controlled from distance signaling of presence of   input voltage 220V  and 
control working capacity power supplies (``dry contacts``).
        UPS is intended for operation in a temperate climate with temperature ambient air from minus 10 to plus 40 º C
and relative humidity up to 80% at plus 25 º C.
  Distinctive features of unit:
- UPS possibility to connect two batteries to the control of their working capacity;
- battery (AB) can automatic charge and subcharge;
instantaneous switching of burden on the output voltage from a battery and in a reverse order accordingly;
  at disappearance and appearance of  input voltage;
- battery  can switch off  automatically with deep discharge;
- digital readout of output voltage, load current, the charging current (discharge) the battery;
-correction of charging voltage depending on the temperature of  battery  and monitoring their performance.
