AC 220V 4000W Variable Voltage Regulator Speed Motor Fan Control Controller

Specifications:
Type: Voltage Regulator
Input Voltage: AC 220V
Output Voltage Range: 0-220V Continuously Variable (The voltmeter will NOT work when the output voltage is less than 5V.)
Power Limit: 4000W (Fits 2000-3000W Resistive Load)
Rated Current: 9A
Max Current: 18A
Plug Type: US
SCR Model: STMicroelectronics, BTA41-600B/800B

Features:
- Zero lag, silent work, stepless speed regulation and wide range of uses.
- For household electrical appliances, industrial appliances, scientific experiment instruments, electrical equipment.
- Clear digital display provides precise numbers.
- Flame retardant insulation shell ensures your safety.
- Independent switch control.

Notes:
- With load free circuit, the voltmeter measures virtual voltage. Only with loads above 20W can it measure the actual voltage.
- Input and output current are both alternating current.
- Power limit could reach 4000W under resistive load. When it’s under inductive load, power limit is only about 1/3 of 4000W. Resistive load includes tungsten lamps and heating coils. Inductive load includes series motors. Electronic products with circuit boards shall be used with caution.
- The metal shell shall be grounded.

Package Included:
1 x Voltage Regulator
