Selpro VTS 312 three-phase fan speed controller
Speed control of 3F fans by current, voltage or PWM input, max. 8kVA
In stock
- Allows changing the speed of three-phase motors (mainly fans) depending on the value of the analog input
- The speed of fans can be controlled by 0..5V, 0..10V, 0..20mA, 4..20mA, or PWM signal 3..20V
- Direct function (as the input value increases, the output increases)
- Customizable control parameters
- Overdrive up to 150% (10s once every 3 minutes)
- Internal protection against overload, phase failure, etc.
- Supplied in IP55 box

The SELPRO VTS 312 from the SELPRO VTS series of three-phase controllers, built into an IP55-rated electrical box, allows the control of fans in direct dependence on the control signal. This can be either current (0...20mA, 4...20mA), voltage (0...10V, 0...5V) or PWM. The controller also includes the necessary logic for the control inputs and allows a wide range of configuration options, depending on the requirements of the installation.
