Description
LOW COST EC FAN SPEED CONTROL MODULE
SETS MIN. & MAX. SPEED & RUN.
Typical application is for setting the limits of minimum & or maximum speed to an EC fan for air balancing by limiting the 0-10vdc control output from some other controller producing a 0-10vdc signal.
Note as this device works on the principle of working with the signal source to sink or source a 0-10v signal and as such it is Not suitable for use with output devices that produce their output via a series diode. To work with devices that do output their signal via a diode use instead ECF1-D
Or can be used as a stand alone device to set a fixed EC fan speed, although alternatively consider our new lower cost module AWEC-1 for stand alone applications.
