## Description

3pcs DC-DC high voltage boost converter 8V-32V to ±45V-390V ZVS step-up booster module capacitor charging power supply module Specifications: Modular nature: Non-isolated boost module Input voltage: 8~32V input(the default is 10~32V input.) Input current: 5A (Max) Output voltage: +45~390V continuously adjustable (default output ±50V) Output current: 0.2A Max(with input, output pressure related,the higher the output voltage, output current is smaller) Output power: 40W (Peak 70W) Working temperature: -40 ~ + 85 degrees (ambient temperature is too high, please enhance heat dissipation) Operating frequency: 75 KHz Conversion efficiency: up to 88% (efficiency and input and output voltage, current, pressure-related) Quiescent current: 15mA (12V liter 50V, the output voltage, the higher the current will increase too quiet) Short circuit protection: Yes.(input 10A fuse, please do not directly short circuit and pull arc! Because it may damage the rectifier device, if you want to do this, please connect the series power resistor to limit current) Over current protection: Yes. (Input current exceeds 4.5A, reducing the output voltage) Over voltage protection: Yes. (Output voltage exceeds 410V, lowering the output voltage) Input reverse polarity protection: Yes (not self-recovery, reverse will burn the fuse, try not to reverse.) Installation: Four 3 mm screws Wiring method: terminal-free welding output Size: 60 x 50 x 20mm Note: The module output is high voltage, on people, animals have life-threatening, the course please pay attention to safety precautions. Manual measurement, with small error. Please check size in detail before purchase. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness. Package Includes: 3 x Booster Module

Review: Decent power - These work good with a 12v power supply. Good clean plate voltage and nice voltage range. 12volts is handy for the filaments.
Review: They work, but may need some modding to work well - So far they work, but to comment: The good: They do work, voltage will adjust The mixed: High ripple, I added a diode and cap on the output to run a 60v led filament. This mod makes a huge difference. Screw adjustment is touchy, also don't like making the adjuatments right near the HV outputs

## Questions & Answers

**Q: Can the negative and positive output terminals be used to double the voltage?**
A: I'm not 100% sure, but if I can remember correctly, Yes they can. Again not 100% but you can always buy and try as the item isn't overly priced. I used mine to control the power output for my nixie tubes. I wish I could be more help..Good luck with your project!

### ⭐⭐⭐⭐⭐ Great value, works really well as a HV power supply for electrophoresis.
*by A***N on September 11, 2023*

By combining this power supply module with a USB C decoy board and a digital volt ammeter it was really easy to create a handy little high voltage power supply. Definitely worth the purchase to get a 350V variable supply. BTW, this module delivers a + and - 350V so can actually deliver 0 to 700V DC!
