InPower DBT-LD-02 Data Bus Throttle Control InPower's fast idle electronic throttles provide elevated engine idle speed when the vehicle is stationary. This increased speed provides higher power levels for heavy alternator loads, air conditioner systems, and power take-off (PTO) applications. InPower's throttles are fully interlocked to ensure safe operation in an elevated idle mode. Individually adjustable speed presets allow different speeds for multiple applications, such as air compressors or aerial lifts. A data link to the engine controller ensures precise speed control, interlocking, and operation of the diagnostic LED indicators.
