## 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).
