Frequency converters of CSI series are designed for shockless start-up and speed control of asynchronous electric motors and valve motors with permanent magnet excitation with power from 1.3 to 7.5 kW. The main area of application is industrial engineering, automated ventilation systems, control of pumps in water treatment systems, water drainage, etc.
The frequency converter provides: protection from the following: protection of the motor speed and control of the rotation speed. Frequency converter provides: protection against short-circuit in the load by built-in current limiter; protection against exceeding the permissible temperature of power circuit elements; protection against phase failure or current skew in phases; measurement of current in the load; protection against excess output power; measurement of voltage on the load; digital and analogue control; automatic restart after emergencies; LED indication of status and alarms.
