The MT830 series high voltage solid state soft starter (hereinafter referred to as soft starter) adopts high performance thyristor and specialized insulation materials combined with modern power electronic control technology. It realizes soft starting, soft stopping, energy saving and various protection functions of the motor, and is specially designed for constant-speed AC motors.

This device features small starting current, smooth starting, and prolongs the service life of motor and starting equipment. It is widely used in various centrifuges, fans, pumps, conveyor belts, and other dragging systems and machinery equipment.

• Adopting solid-state high-voltage high-power components, low heat generation, no noise; fiber optic trigger, high and low voltage isolation
• Comprehensive protection functions including over-current, overload, over-voltage, under-voltage, phase loss, current imbalance, and more
• Low-voltage commissioning function for component testing
• Capacitive absorption network provides over-voltage protection and reduces dv/dt impact
• Multiple control methods: local, machine-side, DCS, communication remote control
• Built-in RS485 communication interface with Modbus control protocol
• 7-inch full-color touch screen with multi-language support and intuitive operation

The high voltage soft start cabinet converts high current starting into progressive starting, offering several benefits for air compressors:

• Reduces starting current, avoiding instantaneous excessive current and lowering grid load
• Extends equipment lifespan by reducing mechanical pressure during startup
• Improves operational efficiency by preventing mechanical component wear
