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 over current protection+soft boot-up. When over heat, the module will turn off, you need to re-power on to reset the module; 
4. We recommend working under 5V only,no over 6V.
5. More stable HV output, even for the heavy loader, the max output voltage only 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 separated 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 8PCS IN-14 NIXIE tubes(Or 4PCS IN-18 with all segment "8" been light up) + 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(3V3 or 5V MCUs are all fine).

Pin Functions

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=170.4V;
2. Lighting up 8PCS IN-14 tubes, the HV output=168.6V; Worked fine under 24*7 condition.
3. Lighting up 4PCS IN-18 tubes, the HV output=168.2V; Worked fine under 24*7 condition.
No audible noise;
4. Lighting up 6PCS IN-18 tubes (For testing only) (We use a 5.35V 2A USB power,All with number "8" been lighted up), the HV output=167.5V, all the tubes can be lighted up in high brightness.(Now Vin=5.13,Iin=1.05A) After working for few minutes, the module goes heat, But the input current been stable, after the over heat the module entered the protection mode.
5. Working under 12Vin(For testing only, do not work under this voltage),the module still works,but seems have a little bit audible sound when press the top of the transformer.

When driving a 10K standard resistor,the output current is 17mA, efficiency is ~84.2%.

When under heavy loader,eg:output over 18mA,under 24*7 condition,the Max temperature of the transformer is about: Room temperature+20℃;Other parts get almost no heat.

Note:
We may not be able to provide extra technology support!
We may will change the Outlook/Circuit/PCB/Components etc. without notification!
It's DIY stuff,sometimes may need 3~5 working days for assembling and heat testing!

Contains:
1PCS HV5W module only, ready to go.(without any tubes, without power adapter, without wires;)

Notes:
1. En pin = high (default) will turn the module on.
2. 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.
