A3RW-4.0 is an efficient transformer speed controller designed to precise rotation adjustment of three-phase fan motors in industrial installations. Allows On/off fan and smooth five-speed control By changing the power supply voltage.
The controller is closed in solid metal housing for surface mountingresistant to working conditions in a technical environment. On the front panel there is a control knob, an independent switch and alarm control, indicating the state of operation of the device. The control circuit is secured with a fuse.
The A3RW-4.0 is equipped with freezing protection (FS) and thermal protection of the engine (TK), which effectively protects the installation and drive from damage. Device meets requirements Insulation class II and is made according to the standard EN 61558-2-13.
