AC 220V 5000W SCR High-Power Thyristor Electronic Voltage Regulator

AC 220V 5000W SCR High-Power Thyristor Electronic Voltage Regulator is an enclosed high-power AC phase-angle dimmer, thermostat, and motor speed controller housed in a finned aluminum-alloy shell with a rotary control knob. Built around a high-current bidirectional thyristor (SCR / TRIAC) with an integrated RC snubber protection network, it smoothly adjusts 220V AC mains output from ~0V/10V to 220V AC for resistive heating loads up to 5000W peak (2200W–3000W continuous) and brushed universal AC motors.

Key Features:

• 5000W Peak High-Power SCR Core: High-voltage bidirectional thyristor regulates 220V AC power for electric stoves, water heaters, incandescent lamps, and universal motors (recommended ≤2500W for continuous long-term operation).
• Full-Body Finned Aluminum Enclosure: Extruded aluminum casing acts as both a protective touch-safe housing and a large-surface-area heatsink.
• Smooth Rotary Knob with OFF Click: Front potentiometer dial provides stepless 0%–100% voltage adjustment.
• Built-In Peak Voltage Absorber (RC Snubber): Protects the silicon-controlled rectifier against inductive kickback and mains voltage surges.
• Covered Screw Terminal Block: Heavy-duty barrier terminals under an insulated cover ensure safe AC mains and load wiring.
