DC-DC Module 400W Adjustable Step-Down Constant Voltage Constant Current Power Module

This non-isolated step-down module provides continuously adjustable constant voltage and current output for powering various electrical equipment. It supports a wide input range of 10.5 to 60 volts and delivers up to 280 watts or 12 amps of output power. 1. The unit accepts an input voltage of 10.5 to 60 volts and produces a continuous output voltage ranging from approximately zero to 45 volts, calculated based on the input level multiplied by 0.8. 2. Operating at 92 to 96 percent efficiency, the module includes a 15 ampere input fuse that safeguards against reverse polarity connections and features an indicator light for monitoring constant current battery charging status. 3. Constructed from a blue printed circuit board, the device relies on natural air circulation for heat dissipation during routine operation. 4. Each package contains exactly one module with no additional components or accessories included.
