## Overview

This High Voltage DC-DC Boost Converter transforms a 12V input into adjustable high voltage outputs ranging from 150V to 420V, alongside a finely tunable filament voltage from 1.25V to 12V. Designed with high-frequency switching technology, it delivers ultra-low noise power ideal for tube preamps and Nixie tubes, all within a compact, easy-to-integrate module.

## Description

High Voltage DC-DC Boost Converter 12V to 150V-420V 170V 230V & 1.25V-12V 6.3V Filament Adjustable Step Up Power Supply 2-Way PSU Regulator Module for Tube Preamp/Nixie Tube

## Features

- DC12V Boost Converter High Voltage Filament Filter Power Supply Board, with a set of filament and a set of high voltage, two sets of voltage adjustable. [Note: The higher the output voltage, the lower the output current. This has nothing to do with product quality.]
- Input voltage 12VDC, Output high voltage 150V-420VDC and 1.25V-12V DC filament voltage regulator is adjustable.
- Due to the use of high-frequency switch, no effect on the audio, signal to noise ratio is very high.
- PCB Size: 90x55x32mm/ 3.54x2.16x1.25inch(LxWxH) (Note that the size of the filter capacitor may be different, and the parameter value is the same, and we will ship it randomly.)
- 20K potentiometer can adjust filament voltage (1.25V-12V DC, max 3A) ; 30K potentiometer can adjust high voltage voltage (150V-420V DC); 1K potentiometer(near the heatsink) can adjust high voltage current (30-40 mA).

## Customer Reviews

### ⭐ Another batch of bad HV regulation.
*by G***S on September 12, 2025*

Like most problems other are having. I purchesed 2 a few months ago and they work fine. I purchased two more last week and they are both bad. The HV regulation does not work. Either bad or damaged parts.Someone should notify the manufacturer to see if they can fix the problem, since it is a very useful power supply. I NEED IT!

### ⭐⭐⭐⭐⭐ Engineer

Very good

### ⭐⭐⭐⭐ Vibration safety
*by A***  on July 20, 2025*

Works Perfectly ! Coil must be glued by silicon!
