Brochure states the design draws on Western European technology and offers large capacity, high efficiency, no waveform distortion and balanced voltage regulation. It accepts varied loads, momentary overload and continuous duty, with manual/automatic changeover.
Protection covers overvoltage, overcurrent, phase loss, phase sequence and automatic protection for mechanical faults. The brochure describes compact size, light weight, convenient installation and reliable operation.
S: three-phase; B: compensated; W: voltage stabilizer; suffix: capacity. The operating-condition text also covers DBW units.
Low-voltage distribution end users with low or widely fluctuating voltage, and equipment with substantial load changes: lifts, cranes, mixers, textile machines, printing machinery, large CNC machines, electroplating plants, stone-processing plants and other loads requiring stable voltage.
Ambient temperature −15 to +40°C; altitude <1000 m; relative humidity <90%.
No gases, steam, chemical deposits, dust, dirt, explosive or corrosive media that seriously affect insulation. No severe vibration or jolting at the installation site.
