EMS PRO Lite

The EMS Pro Lite is a customizable pump controller designed specifically for dewatering and irrigation applications.

This versatile unit supports both mechanical and J1939 electronic engines, thus eliminating the need to stock multiple controllers. A step ahead, the EMS Pro Lite is Tier 4 and Stage IIIB/IV ready. This includes displaying the current urea level % on the LCD. A microprocessor-based controller, the EMS Pro Lite’s operating parameters are field adjustable without the need for a computer. However, the EMS Pro Lite can be modified for use with a remote modem or in a SCADA system with MODBUS* RTU protocols on either an RS232 or RS485 port. The robust EMS Pro Lite is engineered for 12 VDC systems (8 VDC minimum to 14.4 VDC maximum) and a wide operating temperature.
