Item Description

Features

• Drive unit capable of controlling DC Brushed or Brushless motors.
• Capability of closed-loop operation with feedback from a tacho-generator, Optical encoder or the Armature Voltage
• Operation in the PWM technique. The power bridge consists of in rugged power MOSFET transistors.
• Capabilities of 4 – quadrant DC Motor control
• Full isolation from the AC mains in both the control and power sections
• Power supply is from AC mains 3 – Phase 380 – 415 V . The power rating is 1.2KW The nominal output voltage is from -200 to +200V DC
• Suitable for motors of both the permanent magnet type and separate Inductor type. The trainer includes on-boards power supply for a field inductor, with field current monitor. The nominal field supply is 220V DC.
• On-board reference generator
• On-board switch-selectable mode operation. (GO/STOP; RUN/HOLD; FWD/REV; etc)
• Adjustable current limitation, acceleration/deceleration ramp generator.

Sci-tech PWM DC Motor Control Circuit Trainer Model ETR 033 is a DC Motor driver/controller designed to be used as a training aid in courses of industrial electronics and electr0technical studies

The trainer is suitable for use on desktop.

The trainer is a three –phase, 380-415 V AC operated unit (other voltages are pre-set on request) capable of four quadrant drive or DC Motors up to 1.2KW. Separate Inductor type and permanent magnet type motors can be used.
