Dimmer, AC 220V 9A 4000W SCR voltage regulator motor fan speed controller

General Description

The 220V 9A 4000W AC dimmer is a voltage regulator designed to control the speed of motors and fans. It uses a high-performance SCR for precise regulation and features a thick, high-temperature-resistant metal casing, ensuring durability and safety. This device allows continuous voltage adjustment via a rotary knob, providing a fast response without hysteresis or delay.

Technical Specifications Model: BTA-4000W Input Voltage: AC 220V Maximum Power: 4000W (under resistive load) Power under inductive load: 1/3 of the resistive load Rated Current: 9A Limiting Current: 18A Package Weight: approx. 507g Plug Type: EU plug Output Voltage: 0-220V continuously adjustable (voltmeter does not function if the output voltage is below 5V) Compatibility and Accessories 1 x 220V Speed Controller Application

This regulator is ideal for applications requiring speed control, such as line-excited motors and other electronic devices. It is important to use it with caution, especially with printed circuit boards. Other information: The regulator cover is equipped with a universal multipurpose socket and a current display. It is recommended to connect the regulator to a load of at least 20W to accurately measure the output voltage. The metal casing must be securely grounded.
