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
