BG-AUX-EHPS-DP is a dual-power Electric Hydraulic Power Steering Pump engineered to provide uninterrupted steering assistance for commercial electric vehicles. Combining a high-voltage primary power source with an independent low-voltage backup system, the pump ensures steering functionality remains available even during high-voltage system failures, battery depletion, or emergency situations.

Designed for electric buses, heavy-duty trucks, specialty commercial vehicles, and safety-critical applications, BG-AUX-EHPS-DP offers operating voltages from 250VDC to 750VDC while integrating either 12VDC or 24VDC emergency backup modules.

Available in multiple configurations ranging from 1.5 kW to 3 kW, the system delivers up to 15 MPa pressure and 20 L/min flow for demanding commercial vehicle steering applications.
