Variable speed drives

The VEL 412 speed controller allows manual speed adjustment of single-phase fans for precise control through linear current variation. It supports a maximum power of 150 W. This device includes inductance filters to reduce interference on the power line.

The FSY/FSM speed controllers adjust fan motor speed based on pressure. They provide an output voltage ranging from 99% to 50% of the input voltage, with automatic shutdown below an adjustable threshold. Compact and easy to install, these solutions include built-in surge protection. The FSE modules, producing a 0-10 V signal, control fans in HVAC and refrigeration systems. Ideal for EC motors, they reduce noise and optimize energy performance, with simplified installation and IP65 protection.

XV and XRPW ventilation speed controllers are designed for industrial and refrigeration applications, including temperature or pressure control. Phase-cut operation is suitable for motors up to 500W, 660W, 1000W, 2200W, and 5000W. This family is compatible with controllers equipped with PWM, 4÷20mA, or 0÷10V outputs such as the iPro, XC600, and XM600 series.

Three-phase fan speed controllers with variable voltage motors, XV300K, are compatible with all controllers equipped with PWM, 4÷20mA, or 0÷10V outputs, such as the iPro, XC600, and XM600 series. All models are available in master and slave versions. Operating via phase cutting, their great versatility allows users to install them externally on electrical cabinets without additional protections.
