Product Overview? Powerware Electric Group Co., Ltd. China (Wenzhou actually Clexane Electric Co.) SVC / TND series single-phase high-precision automatic exchange regulator, by contact auto high pressure, servo motor, automatic control circuit etc., when the grid voltage instability or load changes, automatic sampling regulator control circuit sends a signal to drive the servo motor, auto voltage regulator to adjust the position of carbon brush, so that the regulator output voltage adjusted to the rated and reaches a steady state. The regulator has a short delay, overvoltage protection, undervoltage protection can be added with time-lapse function according to user needs. The regulator can be widely used in any place, is an ideal power supply for computer network engineering, household appliances, telecommunications systems, medical equipment research institutes, testing, measurement equipment, factory calibration sets. Lighting equipment, industrial automation equipment and other places any electricity. The main technical parameters of the input voltage 150V-260V output voltage 220V and 110V (0.5KVA-3KVA) 220V (5KVA-30KVA) voltage regulation accuracy phase 220V ± 3% 110V ± 6% frequency of 50Hz / 60Hz 246V ± 4% overvoltage adjustment Time <1- seconds (10% input voltage variation) Ambient temperature -10 ℃ + 40 ℃ temperature 5mΩ
