A.C. & D.C. Drives
Complete frequency converters for a.c.low-voltage motors
Application
Frequency converters are intended for soft starting and speed control of induction and synchronous motors in drives of pumps, fans, smoke exhausters, compressors, converters, conveyers, extruders, rolling mills, etc.
Used in
– public utilities;
– water supply, sewerage, ventilation;
– heating systems, power stations;
– metallurgy, mineral resource industry;
– oil – and – gas producing, cement, chemical industry, etc.
Frequency converters provide for:
- considerable power saving – from 20 to 50 %;
- high power factor ≥ 0,98 and efficiency from 0,96 to 0,98;
- high reliability – due to employing electronic modules of the world leading companies;
- longer service life of equipment;
- substantial decrease of maintenance costs, easy adjustment and servicing;
- exclusive stability at high rotational frequency, high overload capacity;
- maintaining unchanged frequency at any load;
- coupling with automatic systems, availability of interface RS232/RS485.
