Overview: ZTY series of high-precision automatic AC power supply, mainly by contact auto voltage regulator, servo motor, automatic control circuit. When the grid voltage instability or load changes, automatic control circuit according to the output voltage variation to drive the servo motor to adjust the position of contact auto carbon brush regulator on, adjusted to the rated output voltage and reaches a steady state. The introduction of foreign advanced technology products, the use of energy-efficient toroidal transformer, imported for the production of integrated circuits and high-quality components. Therefore, a small size, light weight, high efficiency, no additional output waveform distortion, stable performance, and reliability. Features: 1. Can be adapted to inductive, capacitive and other types of non-linear loads. 2. The power volume ratio, cost-effective, wide range of applications. 3. toroidal transformer structure, small size, low magnetic leakage, low noise. The multi-layer structure brush, long life, low maintenance routine.
