Multichannel power source B3-220
The power module B3-220 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.
- providing pure power supply - 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 10°Ñ to +65°Ñ - resistance to power hits to 800V It is possible to change the rates of supply voltages, channel power (agreed during ordering) B3-220
Electrical parameters: -input voltage ~(220) V of the frequency (50)/(400) Hz or ~(127) V of the frequency (50) Hz from the direct current source (accumulator) (24,0) V (automatic switching in case of miss of network and back – after its restoration); - 9 stabilizing output voltages:
- galvanic isolation of the input/outputs; - remote on/off, remote fail signal; - resistance to voltage pulses to 800 V; - protection from overload/short circuit at the output with automatic return to the operating mode after the ending of the overload/short circuit; - noise level at the output is not more than 10 µV; - typical efficiency factor during all-mains operation is 70%, during accumulator operation – 81%.
Climatic parameters: - application type – equipment of the groups 1.1, 1.3, 2.1.1, 2.2.1, 2.3.1 of the climatic version “UHL” according to the GOST ÐÂ 20.39.304-98; - operating temperature range is from minus 10 °Ñ to +65 °Ñ; - limit operating temperature range is from minus 60 °Ñ to +70 °Ñ; - resistance to hyperhumidity to 98% (at 35 °Ñ); - resistance to low atmospheric pressure to 90 mm Hg (aerotransportation).
