The Kussmaul Battery Saver Low Ripple HO is a heavy-duty 20-amp power supply with an integrated load transfer relay designed to prevent auxiliary electronic equipment from discharging the vehicle battery while the vehicle is connected to 120 VAC shore power. Engineered for emergency and specialty vehicles, the Battery Saver provides clean, low-ripple 12 VDC power for sensitive electronic equipment such as mobile data terminals, computers, and other onboard electronics.

When shore power is connected, the regulated switching power supply converts 120 VAC input power to 12 VDC and automatically transfers the connected auxiliary load from the vehicle battery to the Battery Saver. A fast-acting transfer relay provides virtually uninterrupted power during the transition, while the low-ripple output helps prevent electrical interference with sensitive equipment.

Electronic current limiting protects the unit against overload conditions, and a front-panel LED provides convenient confirmation that the power supply is operating. Built with a heavy-duty enclosure and components for demanding emergency vehicle applications, the Battery Saver Low Ripple HO provides dependable auxiliary load management while helping maintain vehicle battery charge during extended station time.
