A Linear Potentiometer Included

Orscheln Products’ EV2 vernier controls for buses utilize a linear potentiometer. Potentiometers are designed to translate the mechanical position into an electrical signal. This is so it’s able to precisely and effectively control the engine from an entirely remote location.

Pre-Set and Protected EV2 controls

The custom EV2 vernier controls that Orscheln creates for buses are pre-set. They are pre-set prior to leaving the manufacturer. The potentiometer is sealed for protection against any outside sources that may damage the product. This means OEM and aftermarket customers will not need to make adjustments in the field. Protecting and pre-setting Ev2 controls will help consumers receive efficient and effective products that are ready to be put to use.
