HIGH COUNTRY TEK - EPC, Electronic Pump Controller - A Multi-Function SAE J1939 Compatible Module

The EPC controller from HCT is designed to control variable displacement hydraulic pumps that can operate with or without swashplate feedback.

The controller has multiple output options that allows it to control pumps using one valve for 0 to 100% flow, two valves for 0 to 100% flow in A or B directions or one valve offset to mid position to give 0 to100% flow in A or B directions.

The module will accept industry standard command and feedback signals of 0-5VDC, 0-10VDC, 4-20mA or Pulse and can also accept digital commands from SAE J1939 systems allowing this to become a remote intelligent node on a mobile networked solution.

All functions are annunciated by colored LED's, while all the internal electronics are fully protected from environmental extremes by the total encapsulation in flame resistant resin. The use of 12 way heavy duty, industry standard Deutsch connectors gives the unit a full IP69K rating and the sealed mini-B USB connector gives an easy direct connection the user PC for configuration, data logging or diagnostics.
