This adjustable boost converter module provides a stable higher voltage from a lower voltage source, enabling operation of devices when a higher voltage is not readily available. It accepts DC input in the range 4 to 35V and outputs DC voltage from 5 to 45V. Key benefits Reliable higher voltage from common sources: expands the range of equipment you can power without a dedicated voltage supply. Precise and adjustable: output voltage is set with a potentiometer and has a control accuracy of 0.1V. Clear readout and easy operation: a LED display shows either the output voltage or the input voltage, selectable with a button press. current capability: up to 5A output current and up to 100W power for versatile loads. USB port for mobile devices: supports current charging via its USB port, suitable for phones and other USB powered devices. Simple wiring: screw terminals for both input and output provide straightforward connections. What makes it stand out Wide adjustable output: 5 to 45V to cover a broad range of devices, from small electronics to higher voltage applications. Realtime voltage monitoring: LED display and a user friendly toggle to monitor either output or input voltage. Robust current handling: designed to deliver up to 5A at up to 100W, suitable for demanding loads. Practical connectivity: screw terminals for secure input and output wiring, plus a USB port for convenient charging where needed. Technical specifications Input voltage: DC 435V Output voltage: DC 545V Maximum output current: up to 5A Maximum power: up to 100W Adjustment: adjustable via potentiometer Display: LED readout showing output voltage or input voltage Display mode select: button press to switch between showing output or input USB port: supports current charging for phones and similar devices Terminals: screw terminals for both input and output Applications and use scenarios Off grid and solar setups: from solar panels or battery banks, boost to a suitable voltage (within 545V) to power regulators, charging circuits, or other equipment that requires higher voltage than available. Vehicle and mobile power: from a 12V vehicle battery, convert to a higher voltage such as 19V for laptop charging or other devices, with up to 5A available for load. USB charging and portable electronics: while boosting a source, use the USB port to charge phones or power USB devices, enabling multi load management from a single module. This boost converter module provides a practical, reliable solution for increasing voltage when higher voltage sources are not available, with clear readouts, precise control, and flexible connectivity for a range of common applications.
