DG series isolation transformer in the power grid not only has the function of changing voltage, but also can isolate the power grid to the equipment harmonic interference, to protect the heat generated by the machine and insulation materials to reduce the life. (380V in → 220V out, 380V in → any voltage output, 220V in → any voltage output) specifications between 100VA ~ 500KVA, DG isolation transformer is widely used in AC 50/60HZ various power supply occasions. Various input and output voltages, coupling groups, adjusting tap positions, winding capacity distribution, secondary winding equipment, whether to require protective case shell, etc., can be designed and manufactured according to the user's requirements. Power 500VA-50KVA, voltage can be customized
