Use

This general-purpose variable frequency drive is designed for regulating the rotation speed of an AC electric motor with a maximum power output of 22 kW. This unit is only suitable for general ventilation systems.

Features

The drive construction prevents forced air flow passage through its internal electronic components. The internal circuit boards of are well-protected.
