Shanghai Wen Feng Electric Co., Ltd. specializing in the production regulator, cheap

SBW / DBW-SG series single, three-phase power automatic compensation regulator transformer (hereinafter referred to as regulator), is the introduction of Western Europe to absorb advanced technology, combined with China's national conditions, to stabilize the AC voltage and design. When the external power supply network voltage fluctuations or load changes caused by voltage fluctuations, can automatically maintain a stable output voltage. This series of products compared with other types of regulator with large capacity, high efficiency, no waveform distortion, stable voltage regulation, etc., applicable to a wide range of load, can withstand instantaneous overload, long-term continuous operation, manual / automatic switch freely offers over voltage, over current, phase, phase sequence protection and mechanical fail-safe, as well as small size, light weight, easy installation, reliable operation. It can be widely used in industry, agriculture, transportation, telecommunications, military, railway, scientific and cultural fields of large mechanical and electrical equipment, metal processing equipment, production lines, construction equipment, elevators, medical equipment, textile embroidery equipment, air conditioning, radio and television and household appliances, lighting and other needs of regulated spaces range: This series of regulators has been widely used in computer industrial and mining enterprises, printing, telecommunications, railways, construction sites, schools, hospitals, hotels, national defense, scientific research and other departments, precision machine tools, precision instruments, laboratory equipment, elevators and production lines in the power regulator. Also applies to the power supply voltage is low, stable place all the necessary voltage fluctuations large low-voltage distribution and load changes in end-user a larger electrical equipment, such as lifts, cranes, mixers and so on. Technical parameters: Input voltage single-phase 176V-264V, three-phase four-wire phase voltage 175V-250V phase voltage, line voltage 304V-456V output voltage single-phase 220V 110V 480V 380V 200V 220V three phase output accuracy can be ordered from 1 to 5 (can be adjustable) Frequency 50Hz / 60Hz Efficiency 95 (power level above 50KVA) Response rate 1.5S Ambient temperature -10 ~ + 40 Insulation resistance 5M Ω overload twice the rated current to maintain one minute waveform distortion No additional waveform distortion overvoltage protection, overcurrent, phase, phase
