UPS D300-12S

  UPS is designed to supply the various radioelectric equipment, gas boilers, etc. UPS works on the principle of
"on-line" (dual voltage conversion: AC-DC-AC). AC input voltage from the network is fed to power supply, where
 it is converted to DC voltage 13,8 V. This voltage feeds inverter, and part is used to charge the battery.
Inverter to working constantly generates a stable voltage of 220V, 50Hz,  regardless of the parameters of the 
input voltage. When loosing the input voltage transition occurs on the power inverter from the battery with zero
switching time, without changing the amplitude and phase of output voltage. When working on the network,
the frequency of the output voltage is synchronized with the frequency of the input network.
 CAUTION! When the gas boiler feeding from UPS D300-12S exclude emergency  not recover protection
acting  interruption of gas supply at a small flame in the burner.  
  Excellent features of unit:
- overvoltage protection at the network (input voltage 265V) ;
- protection against deep discharge battery;
- protection against overload and short circuit, the audio alarm and warning light;
- effective suppression of impulse noise;
- an instant switch from network (input voltage) to battery and vice versa ;
- optimal charging the battery (characteristic of I / U).
