Domestic decade Brand:constant voltage transformer china,Sunel transformer hot in clearance Sunel new transformer co., LTD constant voltage transformer primary power when switched on, the resonant circuit start-up, so that the secondary core shallow saturated, forming a constant alternating magnetic field, the magnetic flux density in a certain range, largely unaffected by the input voltage change, then the secondary winding induced voltage constant. constant voltage transformer efficiency, size and weight similar to ordinary transformer, when the core material better when the mains voltage is 160-250 volts change, in this case, the primary input current is only a complementary role of energy, bi-directional filtering to eliminate clutter grid, with good anti-jamming capability, the output is a sine wave or quasi-square wave types. Sunel new transformer co., LTD constant voltage transformer is a precision electronic equipment, computer and CNC equipment ideal power supply, set the voltage regulator, isolation transformer as a whole.
