RNHV SERIES HIGH VOLTAGE FREQUENCY INVERTER
1. Structure of Product
RNHV series high voltage frequency inverter (VFD or AC Drive) consists of
phase-shifting transformer, power unit and controller. As a VSI (Voltage Source Input)
converter, the product adopts the CSML (Cell Series Multi-level) technology. With high
reliability and easy-operation feature, it meets the requirement of speed control for loads of fans and pumps.
2. Features
1) Smooth operation at ambient temperature up to 50 °C without capacity reduction.
2) Super large margin design makes power unit designed and operated under 120% of
load. All electronic components are designed and evaluated with 90% derating
according to national standards.
3) The product provides three kinds of control modes: V/F, speed sensor vector control
and speed sensorless vector control.
4) Friendly English / Chinese interface offers strong man-machine adaptability. Further the
product is featured with super large industrial grade touch screen, more comprehensive
digital monitoring interface and broader storage space for software upgrade.
5) Power unit bypass function allows derating operation when at most 6 units are
bypassed.
