FST-500 Mini-type SVC Frequency Inverter

FST-500 Mini-type SVC Frequency Inverter

FST-500 Mini-type SVC Frequency Inverter

The FST-500 series is a new generation of non-inductive vector frequency converters, with low speed rated torque output and ultra quiet and stable operation. The built-in PID function can easily achieve PID closed-loop control, advanced automatic torque compensation and slip compensation functions, and has swing frequency function, complete protection and alarm function, and multiple parameter online monitoring and adjustment, which can meet the various needs of customers to the maximum extent. Compact size, mini appearance, and more convenient installation.
