The 936V to 28V DC power converter is an automatic buckboost device designed to deliver a stable 28V output from a wide input range. It automatically steps the voltage up or down as needed, ensuring consistent operation for 28V equipment even when the source voltage varies from 9V to 36V. The unit is sold as a single piece. Key benefits Provides a constant 28V output from sources that vary between 9V and 36V, reducing equipment resets and performance issues caused by fluctuating supply voltage. Automatic stepup and stepdown operation simplifies installation and use, removing the need for manual adjustments. Wide input compatibility makes it suitable for diverse power sources, including automotive, industrial, and remote systems. Compact, singleunit design for easy integration into electrical or electronic installations. Sold as a single unit (1Pcs), making it straightforward to specify and for projects needing a 28V supply. Key attributes Functionality: automatic DC power converter with stepup and stepdown capability to maintain a 28V output. Input range: 936V DC. Output: 28V DC. Current rating: 3A (the listing notes a 3A variant; the title also references broader current options in the range of 5A30A, indicating available variants with higher current ratings). Configuration: designed for direct connection to input power source and load at 28V. Compatibility and use cases Automotive and mobile power: suitable for 28V equipment in vehicles or systems that operate from 12V/24V electrical environments with voltage fluctuations. Solar or batterybacked installations: maintains reliable 28V output from batteries or solar arrays whose voltage can rise or fall during charging and discharging. Industrial equipment and test setups: keeps 28V devices powered consistently in environments where supply voltage may vary due to load changes or charging cycles. How it works Connect the input terminals to a DC power source within 936V. Connect the load to the 28V output terminals. The converter automatically adjusts to maintain a steady 28V output regardless of input fluctuations within the specified range. Usage notes This product is designed to provide a stable 28V output from a broad input voltage range. Ensure the chosen current rating matches the load requirements; the base variant is rated at 3A, with highercurrent versions (5A30A) available according to the product selection. Verify correct polarity during installation to avoid damage to the converter or connected devices.
