High Country Tek, Inc. ( HCT )

is the Fluid Power Industries premier Independent electro-hydraulic

controls supplier with best in class products, service and training.

HCT provides the most ‘Ruggedized’ electronic control solutions

for a wide variety of applications that are successfully applied

across the globe in all areas of the fluid power industry.

To compliment our epc-2 controller, HCT has released a free

software application that allows immediate operation of the

controller with two separate channels, each offering the

opportunity to control dual solenoid projects.

For further system optimization, a free pre-written

Graphical User Interface (GUI) for use with Windows

based PC’s or the HCT TekBook, allows the user to

fine tune the various parameters typically seen in an

open loop controller of this type.

Electronic Controller Solutions for the Global Fluid Power Industry Appendix A: Dual Path with Single coil connections This option allows each input to control one output channel and take full advantage of the 10 bit ( 1024 steps ) resolution offered by the epc-2controller. The dead band is internally set to approx. ±5% of the chosen command, shown here at 250mV for a 5V input and is to allow for any mechanical wear, tolerance or movement in the command potentiometer or joystick.
