Chongqing Three-phase power regulator SBW-500KVA automatic compensation regulator Technical parameters: Input voltage: single-phase 220V ± 20% or 220V ± 30% (when ordering) Three-phase (phase four-wire) 380V ± 20 % or 380V ± 30% (when ordering) Output voltage: 220V single-phase three-phase (phase four-wire) line voltage phase voltage 380V or 220V output voltage accuracy: (2-5%) Adjustable Frequency: 50-60Hz Efficiency: ≥95% (power level above 50KVA) Response time: ≤1.5s (when the external voltage change 10%) waveform distortion: no additional waveform distortion Protection: over-voltage, over current, phase loss, phase sequence protection (single phase and three-phase 150KVA following no phase and phase sequence protection) and mechanical failure Mains features: Three-phase product mains, convenient switching regulator (single-phase no such function) Start: power-selectable automatic start or manual start work way: long-term, continuous unattended work Insulation resistance: ≥2MΩ Electric Strength: frequency sinusoidal voltage 2000V for 1 minute without breakdown and flashover. Chongqing Three-phase power regulator SBW-500KVA automatic compensation regulator is to introduce my company to absorb advanced technology regulator Western Europe, combined with China's national conditions, designed to stabilize the AC voltage regulator. When the external power supply network voltage fluctuations or load changes caused by voltage fluctuations, this voltage regulator (power supply) can automatically maintain a stable output voltage. The voltage regulator (power supply) products compared with other types of regulator with large capacity, high efficiency, no wave distortion open, voltage regulator balance, etc., of the voltage regulator (power supply) for a wide range of loads, energy With instantaneous overload, this voltage regulator (power supply) for long-term continuous operation, manual / automatic switch freely, this voltage regulator (power supply) with over-voltage, over current, phase loss, phase sequence protection and mechanical failure automatic protection, and this voltage regulator (power supply) small size, light weight, easy to install, reliable operation. The voltage regulator (power supply) is 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, embroidery textile equipment, air conditioning, radio, television and home electric smooth, lighting and other needs of regulated places. SBW, DBW series regulator should be used indoors.
