DC-DC Boost Converter 1200W/1500W/1800W – Adjustable Power Module

Q: How do I set the output voltage and current on these boost modules?

Use the onboard V-ADJ potentiometer (with no load connected) to set your desired output voltage using a multimeter for precision. Then connect your load and use the A-ADJ potentiometer to dial in the desired current. Always start with the current at minimum before connecting sensitive loads, and adjust upward gradually.

Q: What protections are built into these boost converter modules?

All models include multiple protection features: input reverse polarity protection (MOSFET-based), short-circuit protection, low battery (under-voltage) protection, and over-temperature protection with automatic thermal fan control. The 1200W model also includes input overcurrent protection (auto-protection above 25A).

Q: What input voltage range do these boost converter modules support?

All three models accept a wide DC input voltage range of 10V to 60V, making them compatible with a variety of power sources including 12V, 24V, 36V, and 48V battery systems, solar panels, and bench power supplies.

Adjustment Guide

Voltage Adjustment

With power connected and no load, use a flathead screwdriver on the V-ADJ potentiometer. Turn clockwise to increase and counterclockwise to decrease output voltage. Adjust in small increments due to large output capacitance. Default factory output: 19V.

Current Adjustment

Turn the A-ADJ potentiometer counterclockwise ~30 turns to set current to minimum, then connect your load and turn clockwise to the desired current. Default factory output: 3A. Do not use a short-circuit method to adjust current on boost modules.

Low Battery Protection Adjustment

Connect the desired protection voltage to the input, then use a flathead screwdriver to adjust RV1 until the UVLO indicator illuminates. Clockwise increases the protection voltage; counterclockwise decreases it.
