770V DC PWM Speed Controller

This DC motor speed controller supports a wide input voltage range up to 770V DC and handles peak currents up to 30A. It features an aluminium alloy enclosure, imported high-voltage MOSFETs, and integrated fuses for enhanced safety and durability. The circuit is optimised for stable, quiet operation with no vibration or audible noise, enabling extended continuous use. Core functions include smooth speed adjustment, immediate stop, and dynamic braking. Designed for industrial-grade reliability in demanding applications such as heavy-duty LED dimming, DC motor control, and high-voltage industrial equipment.
