Products Description
Control Techniques SE23400300 Commander SE Drive Unit

Module Feature
SE23400300 is Commander SE series three-phase AC variable frequency drive manufactured by Control Techniques,designed for speed and torque control of standard asynchronous induction motors. It adopts advanced vector control algorithm,offers stable low-speed torque performance and overload capacity. Built-in digital keypad and display for local parameter setup and status monitoring. Rich programmable digital & analog I/O terminals support external sensor and PLC connection,widely used for conveyors,pumps,fan and general automation machinery.
Working principle
Rectifier converts three-phase AC input into DC voltage, then IGBT inverter module converts DC into adjustable frequency and adjustable voltage AC output to drive induction motor. Real-time monitoring of motor current and speed to realize closed-loop speed regulation, overload protection and soft start/stop function.
Onboard components
Input rectifier bridge,IGBT power module,control PCB,digital operation keypad,LED status display,relay output terminal block,filter capacitor,heat sink.
LED indicators
Power indicator,run status indicator,fault alarm indicator.
Hardware self-diagnosis
Over voltage,under voltage,over current,over temperature,output short circuit,ground fault detection,motor overload monitoring.
Programming software
SESoft software, supports parameter upload/download,real-time data monitoring,fault history reading and drive configuration.
