#12767: AC 220V 4000W SCR Dimmer Controller (220V AC, 4000W)

R226.80

The AC 220V 4000W SCR Dimmer Controller is a device designed for controlling the power of AC loads, such as lighting systems, AC motors, and heaters. It utilizes a Silicon-Controlled Rectifier (SCR) to regulate the amount of power delivered to the load, allowing for smooth and adjustable dimming or speed control.

Functionality:

• SCR Control: The dimmer controller uses a Silicon-Controlled Rectifier (SCR) as its main control element. The SCR is a semiconductor device that can be triggered to conduct current when a small control signal is applied to its gate terminal.

• AC Power Control: The primary purpose of the SCR dimmer controller is to adjust the amount of power delivered to AC loads. It achieves this by controlling the point at which the SCR is triggered to conduct current in each AC cycle. By varying the trigger point, the controller effectively adjusts the average power delivered to the load.

• Dimming and Speed Control: The device is commonly used for applications that require dimming or speed control, such as lighting systems, AC motor speed controls, and heaters. It enables smooth and gradual adjustments to the power level of the connected load.

• High-Wattage Loads: The SCR dimmer controller is suitable for high-wattage loads, including those with power ratings up to 4000W (4kW). This makes it ideal for applications where significant power adjustment is required.

• Average Power Restriction: By controlling the conduction angle of the SCR, the controller restricts the average current flowing through it, which in turn limits the average power delivered to the load. This method of power control is effective and commonly used in AC power regulation.

• Applications: The controller is versatile and can be used in various scenarios where AC power needs to be adjusted, such as in lighting systems to achieve dimming effects, in motor control systems for speed adjustment, and in heaters for temperature control.

The AC 220V 4000W SCR Dimmer Controller provides a reliable and effective solution for adjusting AC power levels in applications requiring dimming or speed control. It utilizes SCR technology to achieve precise control over the power delivered to high-wattage loads, contributing to energy efficiency and optimized performance.
