Multichannel power source B3-222
The power module B3-222 is meant for providing the radio electronic equipment with supply voltage. It is used in radio receiving/radio transmitting devices, requiring high stability of supply voltages.
- low pulse and noise level at the output - using in radio receiving devices and other sensitive equipment - tough operation conditions in special-purpose equipment - high reliability - protection from fault, overload - operating temperature range is from +5°Ñ to +70°Ñ
It is possible to change the rates of supply voltages, channel power (agreed during ordering)
B3-222 Electrical parameters: - input voltage ~(220) V or ~(110) V with the frequency 47÷63 Hz; - 4 stabilized output voltages:
- galvanic isolation of the input/outputs; - remote on/off, remote fail signal; - transient network voltage deviation 220 ± 20 % (110 ± 20 %), not more than 3 s; - protection from overload/short circuit at the output/ with automatic return to the operating mode after the ending of the overload/short circuit; - level at the feed circuit is compliant with the requirements of the group 1.1.1 according to the GOST Â 25803-91; - typical efficiency factor is 0,75.
Climatic parameters: - application type – equipment of the groups 1.1 of the climatic version “O” according to the GOST ÐÂ 20.39.304-98; - operating temperature range is from +5°Ñ to +70 °Ñ; - limit operating temperature range is from minus 35 °Ñ to +70 °Ñ; - resistance to hyperhumidity to 95% (at 35 °Ñ); - low operating atmospheric pressure to 450 mm Hg.
Constructive parameters: - overall dimensions 128 × 288 × 110 mm; - slip constructive module “Euromekhanica19” (19-inch stand, 3U); - mass is not more than 2,5 kg; - input/package insulation resistance is not less than 20 MOhm in normal climatic conditions.
