Overview
Developed from compensated power-stabilization equipment. High-speed DSP computation, fast AC sampling, RMS correction, voltage/current zero-crossing switching and fast voltage compensation combine metering, regulation and fault diagnosis.
Main assemblies are an isolation transformer, SCR thyristor modules, DSP control core, fast voltage-regulation system and protective devices. Brochure describes a contactless, efficient, energy-saving design combining semiconductor switching and transformer technology.
Applications
Large electromechanical and metalworking equipment, production lines, lifts, medical equipment, embroidery and textile equipment, air conditioning, broadcasting/television, domestic appliances and building lighting in industry, transport, telecommunications, defence, railway and research applications.
Product features
Brochure states efficiency above 98% and low self-consumption; regulation accuracy ±1%; real-time high-resolution RMS voltage/current display with membrane-key operation; independent regulation of the three phases; and a wide input regulation range.
Brochure states a 40 ms stabilization speed, intended for computerized automation, equipment and instruments.
Protection and fault indication include phase loss, incorrect phase sequence, overtemperature, overload, overvoltage, undervoltage, short circuit and blown fuse. Output voltage, overload, over/undervoltage and response speed are presettable within rated limits.
Brochure states momentary overload capability at 100% rated load; continuous operation under difficult grid/load conditions; zero-crossing switching without interrupted current or surge current; and no output-waveform distortion.
No-load losses at rated voltage are stated to be below 0.5%. Bypass permits changeover between stabilized operation and direct mains supply for maintenance.
The brochure links its stated low no-load losses with electricity-bill savings, but supplies no quantified customer saving or measured before/after result.
