SINGLE QUADRANT ANALOG

Gemini pulse width modulated (PWM) DC drives are designed to operate with brush-type PM DC motors. The evolution of Gemini's PWM drives has led to numerous advantages over SCR based and other PWM drives, including:

  • State-of-the-art design
  • Gemini's PWM drives produce less motor heat - which allows smaller, less expensive motors
  • Smooth Operation - High speed switching and exclusive motor inductance compensation provides the fastest response to load and speed changes
  • Audibly quiet - Operates at an inaudible 16KHz
  • Tolerant of low voltage and short duration power outages
  • PWM increases brush life, reducing maintenance
  • Less line current consumption at low speeds

FRACTIONAL HORSEPOWER PWM DC DRIVES

Gemini pulse width modulated (PWM) DC drives are designed to operate with brush-type PM DC motors. The evolution of Gemini's PWM drives has led to numerous advantages over SCR based and other PWM drives, including:

  • Models for 1/100 to 1/4 HP
  • 115 or 230VAC input, 0-90VDC or 0-180VDC output
  • Maximum adjustability - Maximum and minimum speed, acceleration and deceleration, current limit and IR compensation
  • Chassis or enclosure mounting
  • Enable input allows remote control
