Horton Generator Power Panel


DAE Pumps Horton 125 power generators use alternators built for heavy-duty continuous application with marine winding protection. We use Leroy Somer alternators with AREP excitation systems for superior starting capabilities. The AREP system uses two independent auxiliary windings located in the main stator to send supply voltage to the AVR.

Control System

The Horton 125 control system uses a fully diagnostic DeepSea 7310 ECU controller with a large 3-inch display, that is intuitive and easy to operate with all functions conveniently at your fingertips. The controller manages the engine ECU operating system and several safety warnings and shutdowns on various parameters.
