Multichannel power source B3-236
The power module B3-236 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 minus 30°Ñ to +55°Ñ
It is possible to change the rates of supply voltages, channel power (agreed during ordering) B3-236 Electrical parameters: - input voltage (27,0 ) V; - 6 stabilized output voltages:
- galvanic isolation of the input/outputs, outputs with each other; - remote 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 complies with the GOST 25803-91, figure 1, curve 2.
Climatic parameters: - operating temperature range is from minus 30°Ñ to +55 °Ñ; - limit temperature range is from minus 55 °Ñ to +70 °Ñ; - resistance to sea (salt) mist; - resistance to hyperhumidity to 98% (at 35 °Ñ); - low operating atmospheric pressure to 450 mm Hg, resistance to aerotransportation (to 90 mm Hg)
Constructive parameters: - overall dimensions 104 × 288 × 35 mm; - slip constructive module “Euromekhanica19” (19-inch stand, 3U); - mass is not more than 0,5 kg; - input/package insulation resistance is not less than 100 kOhm.
Mechanical parameters:
- resistance transportation by any of the transport means. 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. |
