UPS 1210a has wide input voltage range, 88-264Vac. Nominal output voltage is 13.8V. Device can be constantly loaded upto 10A, and upto 11.5A within 5 minutes. BATTERY type can be standard car battery or gel Pb battery with nominal voltage 12V and capacity between 34Ah and 110Ah. In that case, it is provided uninterruptible power supply for connected device, even if power line breaks off. Autonomy time depends on capacity of used battery and device power consumption. UPS 1210a has power consumption less than 40mA in battery mode. Switch between normal and battery mode, and protection as well, are provided with relay contacts, thus there is no voltage on semiconductors resistance.



Uninterruptible power supply UPS 1210a is intended to use with radio stations and repeaters which nominal input power supply voltage is 13.8V, but it can be used, without restrictions, for power supplying other devices which nominal power supply voltage is 13.8V and its power consumption is not exceeding 140W.
