The Lenze EVS9322-ER is classified as a servo register controller, specifically designed to enhance the efficiency of 4-pole asynchronous motors with an output capacity of 0.75 kW. It accommodates an operating voltage range of 3-phase AC between 320 V and 528 V. This unit is suited for applications requiring a frequency range from 45 to 65 Hz.

For added versatility, the controller is equipped with a backup DC input, which operates at 460-740 V. At an input of 400 V, the device has a power dissipation rate of 110 W. With a total weight of 3.5 kg, it provides a compact solution suitable for a variety of industrial environments.

The EVS9322-ER allows the user to select between two adjustable switching frequencies: 8 kHz and 16 kHz. For the 8 kHz setting, it delivers an output current of 2.5 A or 1.7 A, depending on the load, while at the 16 kHz setting, the output current drops to 1.8 A or 1.26 A.

This controller's power output varies with frequency; it reaches 1.7 kVA at 8 kHz and can provide up to 2.1 kVA at 16 kHz. Peak current ratings indicate a maximum of 3.8 A or 5.0 A at 8 kHz and 2.7 A or 3.6 A at 16 kHz. It has a rated current of 2.5 A when connected to a 400 V mains supply, solidifying its capability for handling a range of operational demands.
