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. |
