500W Boost Step-Up DC Converter 11-27V to 24-50V Adjustable Module
500W Boost Step-Up DC Converter 11-27V to 24-50V Adjustable Module
500W Boost Step-Up Power Supply Module – Adjustable Voltage Output with Display
Take full control of your DC power projects with this high-efficiency 500W Boost Step-Up Power Supply Module. Designed for electronics enthusiasts, engineers, and DIY builders, this converter steps up an 11–27V DC input to a fully adjustable 24–50V output — all while maintaining an impressive 92–95% conversion efficiency. The built-in voltage display makes monitoring output a breeze, and the intelligent temperature-controlled fan keeps the module running cool under load.
Key Features
- Wide Input Range: Accepts 11–27V DC input (output becomes unstable above 27V input)
- Adjustable Output: Smoothly tunable from 24V to 50V DC to match your project requirements
- High Power Output: Rated at 500W continuous output power
- Exceptional Efficiency: 92%–95% conversion efficiency minimizes energy loss and heat generation
- Built-In Voltage Display: Real-time digital readout for accurate output monitoring
- Smart Thermal Management: Temperature-controlled fan activates automatically above 36°C and stops when the temperature drops — extends component life and reduces noise during light loads
- Self-Check on Power-Up: Fan runs for 2 seconds after power-on for an automatic self-test
- Compact & Versatile: Suitable for a wide range of DIY electrical and electronics applications

Frequently Asked Questions
Q: What is the maximum safe input voltage for this 500W boost step-up module?
A: The module is designed to operate with a DC input voltage between 11V and 27V. Exceeding 27V on the input side will cause the output voltage to become unstable and may damage the module. Always verify your source voltage before connecting.
Q: Can I use this boost converter for charging lithium battery packs or powering motor drivers?
A: Yes — because the output is adjustable between 24V and 50V DC and can deliver up to 500W, this module is well-suited for a wide range of DIY applications including powering motor drivers, LED arrays, battery charging circuits, and other high-voltage DC projects that require a stepped-up supply voltage.
Q: Does the cooling fan run continuously?
A: No. The fan performs a 2-second self-check immediately after power-on, then stops. It only activates again when the module's internal temperature rises above 36°C, and shuts off automatically once the temperature drops back down. This keeps operation quiet during light loads.
Q: What does 92–95% conversion efficiency mean in practice?
A: Conversion efficiency indicates how much of the input power is successfully delivered as output power. At 92–95% efficiency, only 5–8% of energy is lost as heat, making this module highly effective compared to lower-efficiency alternatives and reducing the thermal load on your system.
