150V (127–173Vdc) to 400VDC 500W / 400W Charge Power Supply — ACDC and DCDC Boost / Buck Converter Key benefits Converts a midvoltage DC source (nominal 150V, range 127–173Vdc) to a stable 400VDC output, enabling charging or powering 400V DC systems without additional inverters. Supports power applications with the listed power capability (500W / 400W charge), reducing system complexity by combining charging and DCDC conversion in a single unit. Flexible boost and buck operation lets this supply adapt to input variations within the specified range while delivering the required 400VDC output. Why customers need it Simplifies installation when a reliable 400V DC bus is required but only a 127–173Vdc source is available. Eliminates the need for separate converter and charger modules, saving space and reducing wiring and integration effort. Useful in systems where input voltage fluctuates but a stable voltage DC output is required for charging or downstream equipment. Key attributes Input voltage: 150V nominal, compatible with 127–173Vdc input range (DC). Output voltage: 400VDC output as specified. Power: 500W / 400W charge rating (as listed). Functionality: Charge power supply; ACDC and DCDC converter capabilities; supports both boost and buck conversion modes as described. Compatibility: Designed for integration with equipment and battery systems that require a 400VDC supply or charging source and that can accept the stated input range. Integration: Intended for engineered systems where a dedicated 400VDC power source is required; refer to system wiring and safety practices during installation. Applications and use cases voltage battery charging: Use to charge 400V battery packs from a midvoltage DC source in mobile or stationary battery systems. Industrial DC bus supply: Provide a stable 400VDC bus for industrial drives, power electronics, or control systems when only 127–173Vdc is available. Renewable and storage integration: Interface midvoltage DC from generators or intermediate converters to a 400VDC energy storage or power distribution bus. Practical considerations Verify that your system accepts the specified input range (127–173Vdc) and that the 400VDC output matches the downstream equipment or battery requirements. Follow recommended installation and safety procedures for voltage DC systems; consult the product documentation or technical sheet for wiring, mounting, and cooling guidance. Ensure systemlevel protection and monitoring are in place (fusing, disconnects, and appropriate controls) when integrating voltage power conversion equipment. This unit provides a focused solution for converting a 150Vrange DC source to a 400VDC output with 500W / 400W charge capability, combining boost and buck DCDC conversion and ACDC charging functionality for streamlined voltage system design.
