Moshchnaya radiotekhnika

rated output power - 2.0 kW; maximum output power - 2.8 kW; rated supply voltage - DC 400V; Efficiency (depending on frequency) - 95...98%; operating time in CW mode without cooling at an initial temperature of 25°C - 30...60 sec. size with radiator - 310 x 105 x 70 mm; weight with radiator - 3.6 kg. The module has a built-in autonomous temperature protection and RF transistor current protection. There is an input of external blocking of the RF path, which can be used as an input of amplitude modulation. MAG-1K0.LF modules are used to build all Plasma GK series RF generators with frequencies of 0.35...2.0 MHz.
