FM6 Condanser Fan Speed

Product Details

share product

The FM series monophase fan speed control units keep the condenser gas pressure constant by adjusting the fan speed according to the condenser pressure or temperature. In addition to the pressure and temperature sensors, 0-5V, 0-10V or potentiometer can also be connected to provide external control. The soft-start feature softens the fan’s first attempt. In cold weather, the fan applies full power for a short period of time at the start of the fan, thus resolving problems such as fan congestion, snow accumulation, etc. The user-friendly menu allows easy operation without confusion. The desired fan speed can be adjusted in the band frame that the user can adjust.

The FM control units also offer solutions to the needs of monophase motors (suitable for control with phase angle control), heating and dimmers. In addition to temperature, pressure and analogue inputs, other control requirements also provide a complete solution thanks to the increasing or decreasing sloping output function in the band frame that the user can adjust.
