  • Page 3: Principle Of Operation

    1.2 Principle of operation. AWZ 222 is a stabilized transformer PSU with high factor of voltage stabilization. Mains supply ~230V is reduced by a transformer and then rectified by the system of rectifiers and a low pass filter. DC output voltage is gained in the linear regulator and it is adjusted according to the PSU operation type (charging phase and battery maintenance).
