New-HV5W NIXIE High Voltage Module,5V DC in,170V DC out

HV5W 5V to 170V NIXIE High Voltage Power Supply Module
HV5W 5V to 170V NIXIE High Voltage Power Supply Module

This Module is newly design,which can light up about 10PCS IN-14 NIXIE tubes with 10k resistor in serial under the 5V DC in.

Now all of NIXIE fans can use the 5V USB power to drive the NIXIE clocks.

Module is pretty small,and with high eff,the module got almost no heat.

More pictures will be added soon.

NEW-Small HV5W HIGH VOLTAGE NIXIE POWER SUPPLY MODULE PSU-NIXIE TUBE ERA

DANGER! Lethal Potentials Present
THIS MODULE CONTAINS DANGEROUS, HIGH VOLTAGE POTENTIALS. USE CAUTION.
DO NOT TOUCH ANY PART OF THE MODULE WHEN IT IS WORKING.

Tips:
1. Standard 0.1"(2.54mm) pins, easy to be used, can use bread board or DuPont-Wires etc.
2. Please control the input current <=800mA for the low heat working state;
3. Module contains input reverse polarity protection and over current protection. When over heat, the module will turn off, you need to re-power on to reset the module; 
4. Please use high quality and stable input DC source, do not go over voltage;
5. For the heavy loader, the max output voltage may get a little bit drop;
6. If one module's power is not suited for your app,use two or more modules for driving the seperated NIXIE tube(s) group,etc.;
7. Do not connect the modules' outputs in "Parallel Connection"!!!

Description:
HV5W is a newly designed high voltage module, it works under 5V USB power, with ~170V DC output, especially designed for driving the NIXIE tubes. The max power output is enough for lighting up 6PCS IN-14 NIXIE tubes + 4PCS NE-2 neon bulbs. Low EMI and with No audible noise.
It contains an ENABLE pin to turn the module on/off, and can be controlled by an regular logic signal, like a MCU's GPIO PIN.
We use the same module in our new "6-Tube IN-14 Clock" design, the prototype has been working for over 2 month under 24*7 condition, the clock worked fine, and the module got almost no heat.

* You can use the middle 3 pins only.

For 24*7 continually working condition, we recommend you control the input current less than 800mA when under 5V in, it keeps this module working under the low heat condition.

And this module is also suite for driving 6 tubes IN-18 clock, you just need to use two modules for driving it. Each module can drive 3PCS IN-18 tubes + 2PCS NE-2 neon bulbs (as dots) with no problem.

Typical Usage:
For driving NIXIE Tubes;

Simple testing by myself:
By using the 5V/1A5 USB Power Adapter as the input DC source, we tried to light up some NIXIE tubes:
1. No load, the HV output=170.6V;
2. Lighting up 6PCS IN-14 tubes, the HV output=166.2V; Worked fine in 24*7 condition.
3. Lighting up 3PCS IN-18 tubes, the HV output=164.6V; Worked fine in 24*7 condition.
No audible noise;
4.
Lighting up 6PCS IN-18 tubes (For testing only.) (All with number "8" been lighted up), the HV output=162.5V, all the tubes can be lighted up in high brightness. After working for few minutes, the module goes heat, the input current keeps increasing slowly, after the input current went over about 1A3, the module entered the protection mode.

Notes:

2. Module contains input reverse polarity protection.
3. Module contains over current protection circuit, when over power or over heat it will turn off the HV output, you need to re-power on to rest the module.

    Really good news! Gone are the days that nixie tube projects need 12V power supply due to the boost converter's design requirement. Hope to check out the new stuff soon.

    Would you consider publishing the schematic for these power supplies?

    I am a student and would like to know how these work in details.

    Thank you in advance.

    Is the output voltage adjustable by adding a trimmer resistor like on the DIY KIT-USB Power-HV5W-E DC-DC module?

    Webmaster (Sunday, 11 February 2018 20:20)

    This type of HV5W module is not adjustable,you can only replace the ref resistor on PCB to change the output voltage,we have the adj version in a little big PCB ,you can find
    www.ebay.com/itm/131846790948
    for adj version.
