## Description

desertcart.com: High Voltage DC-DC Boost Power Supply Converter Module for Vintage Vacuum Nixie Tube, Magic Eye 6E2 Level Indicator 9V-12VDC Input, 80V-380VDC Output (Green) : Electronics

Review: Good value - Works well for testing nixie tubes. As described. Not expensive.
Review: Don’t short it! But nice and compact. - Good unit. Using for NIXIE project. Tested. Bought two. Both work fine. Remember, the voltage at the output is high. Even though the current is low you can still get a bite! Use caution especially if you have a pacemaker! Things get really exciting then! LOL

## Questions & Answers

**Q: is the output DC or pulsed DC?   i.e. a single polarity?**
A: The output is fairly clean DC.  It has a few mV of noise which is load dependent.  In my case I am using this in a supply for a measuring microphone.  The mic needs super clean 120V at a couple mA, and super clean 200 V at no current.  To clean the output up I used a Sziklai pair capacitance multiplier to get the noise down into the uV range plus an RC filter for the polarizing voltage.

**Q: Schematic of this product.**
A: I was not able to find a schematic for the power supply circuit.

Would have to reverse engineer the board to get the circuit.

**Q: What is required for it to work?**
A: A 12 volt DC 1A wall wart powers this just fine.

**Q: Exactly what type of transformer is needed for the high voltage dc-dc boost power supply converter module?**
A: All you need as a "wall wart" that plugs into the AC wall socket and delivers 12 volts DC.  Cut and remove the coax plug from the wall wart's cord.  Check polarity and connect the + lead with to red and - to black.  A wall wart rated at 1 amp is enough as long as your HV load does not draw more than about 30mA.  By the way, 30mA is about the limit for what this board can do before the inductor's core saturates and the efficiency goes way down resulting in overheating.
