  •  Single phase series precision purification AC voltage regulator

    This series of products are suitable for power supply of electronic computers, precision instruments, copiers, testing equipment, communication broadcasting equipment, automatic control system and other equipment and facilities with high power supply quality requirements. Normal working and installation conditions: 1. Altitude: the altitude of the installation site shall not exceed 1000m; 2. The ambient air temperature shall not exceed + 40. C. The lower limit of ambient air temperature is - 5. C. 3. When the ambient air temperature is + 20. The relative humidity of the air is 90% at C; 4. It should be installed in a ventilated, dry room without direct sunlight, corrosive media and flammable and explosive gases. Wide voltage range: single phase 185v ~ 255v, three phase 320v ~ 430v. 2. High voltage stabilization accuracy: < ± 1%. 3. Strong anti-interference ability: it can suppress all kinds of noise and peak voltage. 4. Fast response time: < 0.1s. 5. High efficiency: > 90%. 6. The output and input voltage detection function is intuitive and clear. Principle and characteristics: This product adopts advanced sinusoidal energy distribution technology, and its main circuit is composed of sinusoidal energy distributor and high power filter in parallel. When the output voltage changes due to the fluctuation of mains voltage or load, the on angle of bidirectional thyristor is controlled by sampling circuit, comparator and trigger, and the current is changed to change the magnitude and phase of compensation voltage to achieve the purpose of stabilizing the output voltage. It has excellent voltage stability and anti-interference performance, voltage digital display, voltage stability accuracy less than ± 1%, response time < 0.1s, can effectively suppress the peak interference of power grid, and the efficiency of the machine is more than 90%.
