General Features include:

• Power MOSFET technology provides smooth, silent, efficient, and cost- effective operation.
• Adjustable parameters enable custom optimization of speed, torque, and braking control.
  
• Half bridge armature and full bridge field provides regenerative braking down to near zero speed.
  
• Anti-stall function helps prevent motor commutator damage.
• Protection : Temperature, Overcurrent & Low Voltage Protection
  
• Can be easily programmed with Stars PD-0711A, or direct from factory.
  
• Timed shutdown of main contactor after pedal is released and vehicle has stopped.
  
• LED status indicator.
  
• Extensive fault detection and diagnostic reporting using a Stars Programmer including (partial list):
  – Throttle and wiring faults
  – Open or shorted motor field winding
  – Open motor armature winding
  – Over-temperature Armature drive failure.

Product Detail :

Introduction :

Stars PQ-series separately excited motor controllers are perfect for systems requiring peak currents from 50A to 300A and system voltages from 12VDC to 48VDC. Stars Separately Excited Motor Controllers are programmable and microprocessor based, with an advanced MOSFET power section for smooth and seamless control of separately excited motors. The motor controller is fully programmable by means of the Stars PD-0711A handheld programmer. STARS PQ-Series motor controllers are designed for use in a variety of small industrial vehicles and in material handling equipment.<Learn More>
