HOFFMAN 791-ECM ECM(VmA) Fan Speed Control

Product Description

The HOFFMAN 791-ECM is an electronic fan speed controller designed to provide proportional speed control for ECM motors. This controller functions efficiently in variable air volume applications and only requires a twenty-four VAC power source. Motor speed modulation is accomplished through a pulse width modulated signal.

Compatible with energy efficient ECM (brushless DC) motors.
Ideal for variable air volume applications.
Input compatible with DC voltage or current.
Product Highlights

This device is suitable for air-moving tasks and works well with both squirrel cage and propeller-type fans. It is also applicable for some direct-drive motor setups.
