10000W SCR Voltage Regulator Motor Speed Controller AC 110V-220V
10000W High Power SCR Voltage Regulator & Motor Speed Controller
Take precise control of your AC-powered equipment with this heavy-duty 10000W SCR Voltage Regulator and Motor Speed Controller. Designed for demanding industrial and workshop applications, this unit handles AC 110V–220V input at up to 75A, making it ideal for electric furnace thermostats, incandescent lamp dimming, fan speed control, electric drill speed adjustment, and a wide range of other resistive and inductive loads. Made in Mainland China.
Key Features
- Heavy-Duty Copper Terminals: 75A large-current copper terminals paired with a robust aluminum shell ensure reliable, low-resistance connections and long-term durability.
- RC Absorption Protection Circuit: Built-in RC snubber circuit on the SCR safeguards against voltage spikes, extending the life of both the controller and connected loads.
- Intelligent Cooling Fan: The upgraded fan features smart switch control that activates only when needed, providing efficient heat dissipation and a longer service life.
- Precise, Lag-Free Voltage Control: A unique trigger circuit delivers accurate, smooth voltage adjustment from 0V all the way up to the full input supply voltage — no dead zones, no lag.
- Wide Application Range: Compatible with 110V and 220V devices including electric furnace wire thermostats, incandescent bulb dimmers, AC fans, electric drills, marble cutters, and more.

Frequently Asked Questions
Q: What types of loads is this 10000W SCR voltage regulator compatible with?
A: This SCR voltage regulator works best with resistive loads such as incandescent bulbs, electric furnace heating elements, and similar devices. It also supports motor speed control for universal AC motors (e.g., electric drills, fans). It is not recommended for use with inductive-only loads like transformers or capacitive loads without proper precautions.
Q: Can this motor speed controller be used on both 110V and 220V systems?
A: Yes. The controller is rated for AC 110V–220V input, making it suitable for both North American (110V) and European/international (220V) electrical systems. Always verify your local voltage and current requirements before installation.
Q: Does the cooling fan run continuously?
A: No. The upgraded cooling fan features intelligent switch control, meaning it activates automatically based on temperature conditions rather than running at all times. This conserves energy and extends the fan's operational lifespan.
Q: What is the maximum power this controller can handle?
A: This controller supports up to 10,000W at 75A for resistive (blocking) loads on AC 110V–220V. Ensure your connected equipment does not exceed these ratings to maintain safe and reliable operation.
