DC-DC bidirectional DC power supply

Product Overview

DC-DC bidirectional DC power supply is a power supply that can flow energy in both directions. It has four working modes: input constant voltage, input constant current, output constant voltage, and output constant current. The four working modes can be switched to each other as needed during operation. The power supply adopts DSP control and silicon carbide power devices, which is an efficient and energy-saving product. The power supply has comprehensive protection measures to ensure the safe operation of the power supply.
