Motor drives

LAEG LD320 / LD350 variable frequency drives

Variable-speed drives for pumps, fans and industrial motors, with PID and Modbus control.

LAEG LD320 / LD350 drives provide vector and V/F motor control, built-in PID and multi-speed operation. Run commands can come from the keypad, terminals or communications.

G versions serve constant-torque loads; P versions serve fans and pumps. Select the voltage, rating and options to match the motor and duty.

Applications

Pump and fan speed control; constant-pressure water supply; air compressors; industrial motor drives. Select the matching version and options for each application.
