Electronic Governors

Wabtec Transit Car Products Electronic Governors

The compact aftercooler used with the E-1A Air Dryer maintains discharge temperature within 5.6°C (10°F) of ambient, with dew point suppression 39°C (70°F) and 83°C (150°F) using the higher performance canisters.  The ES-30 On/Off Governor uses an electronic pressure switch, a mechanical contactor and a DC/DC converter for outstanding adjustability and maintainability.  Additionally, Wabtec now offers the ES-40 (DC motor control) and ES-40A (AC motor control) Electronic Governors, advanced motor switching governors that eliminate the need for motor contactors and electro-mechanical pressure switches.
