Multichannel power source B3-230
The power module B3-230 is meant for providing the radio electronic equipment with supply voltages. 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 +65°Ñ
It is possible to change the rates of supply voltages, channel power (agreed during ordering)
B3-230 Electrical parameters: - input voltage (24,0) V; - 7 stabilized output voltages:
- galvanic isolation of the input/outputs, outputs with each other; - remote and local on/off, remote fail signal; - protection from overload/short circuit at the output with automatic return to the operating mode after the ending of the overload/short circuit; - typical efficiency factor is 0,84 ÷ 0,86; - radio interference level at the output, created during the module operation (discrete frequency components) is not more than: in the range 10…100 kHz – 40 dB;
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 +65 °Ñ; - limit operating temperature range is from minus 35 °Ñ to +70 °Ñ; - resistance to hyperhumidity to 85% (at 25 °Ñ);
Constructive parameters: - overall dimensions 128 × 288 × 110 mm; - slip constructive module “Euromekhanica19” (19-inch stand, 3U); - mass is not more than 3 kg; - input/package insulation resistance is not less than 1 MOhm.
Mechanical parameters:
Reliability parameters: - average mean time between failures is not less than 50 000 hours; - average service life of the block before write-off is not less than 10 years. |
