Nidec ASI Silcovert NH series medium voltage drive:
The Silcovert H Series (TH/NH) is the ideal variable speed drive solution for retrofitting to improve efficiency and reduce environmental impact. It is a multi-level variable speed drive with IGBT power devices and a more efficient and precise control for induction and synchronous motors. The PWM technique with high switching frequency allows an almost sinusoidal motor current with low total losses and very low torque. Its water cooling method permits to achieve high output power ranges. Our H series variable speed drives are compatible with existing motor systems, regardless of brand or age. With our customized retrofit customers can achieve increased levels of safety, reliability and efficiency.
Power range: Water cooling: 2900/14400 KVA
Voltage: up to 4160/6000/6600 V
Output Frequency: 5 – 140 Hz
Applications: centrifugal loads (pumps, compressors, fans), revamping of existing motors, high speed applications.
