## Description

High voltage DC-DC boost converter 8V-32V to ±45V-390V ZVS step-up booster module capacitor charging power supply module adjustable voltage output 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 (with housing for welding output) Size: 60 x 50 x 22mm 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 Included: 2 x Booster Mod

Review: Try one - Meets voltage and current specs. Heat sink runs close to room temperature with output running at 200 v 5 ma. Output voltage seems to hunt plus our minus 1 volt with a constant load and some “noise” on output but still is an off the shelf inexpensive answer for many needs. Just keep in mind this is a Flyback inverter not a linear power supply and great for many projects.
Review: great product - I am able to get the high voltage to 400 needed for testing.

### ⭐⭐⭐⭐⭐ great product

I am able to get the high voltage to 400 needed for testing.

### ⭐⭐⭐⭐ Decent HV supply
*by A***M on July 4, 2023*

It's a decent high voltage supply for the cost. It's not a ZVS circuit, but is based on the UC3843A current mode PWM controller IC. It provides a reasonably stable output, though the peak to peak voltage can be a few volts when operating with low loads at high output voltage. The design seems to set the maximum switching current pretty high, which is fine, but results in the controller operating in pulse skip mode most of the time, so the unrectified secondary output can't really be used in a multiplier circuit. Overall pretty nice. Here is a composite shot of the controller with some annotations in case anyone else wants to tinker with the board.
