Product Announcement from HydraForce, Inc.
The EFDR2 multi-input fan drive controller provides precise, repeatable control of
a TSxx-21 or TSxx-27 proportional fan control solenoid valve coil and one on/off
solenoid valve coil. The controller accepts up to three thermistor inputs for fan control
along with a single switch input for manual activation of the fan reversal function.
Controller input signals can be from a resistive temperature sensor, or analog switch
inputs. The EFDR2 setup parameters are confi gured using a PC, or the Application
Confi guration Programmer (ACP) serial interface, which allows for infrared programming
and fi eld adjustment of the controller. This multi-input fan drive controller is
suitable for a wide range of heavy duty industrial, marine, and mobile off-highway
equipment applications requiring proportional fan control.
