Maximum Output Power:5W (without using of switching transistor cooler). Designed for Nixie tube, VFD tube, Magic eye etc. Shutdown mode are controlled via SHDN logic input. High Voltage Power Supply for Nixie and Valve Tubes: Since in last years nixies displays attracted my attention so much that I bought many of them, I finally managed to design a good power supply and my nixie clock is on the way... [UPDATE: done! Most Nixie tube drivers require the obsolete and hard to find 7441 or 74141 TTL decoder driver ICs, or else high voltage driver transistors. Input voltage can be from 3V to 12V. Easy to use nixie tube driver - only 3 control lines. I am pleased to announce that now you can buy our retro Nixie tube clocks at our online shop. Nixie Tube Power Supply. Welcome to Vintage Nixie Tube Clocks Workshop. Compatible with 5V and 3.3V (IO & VCC). With IN-19 nixie tube. With that in mind, I decided to design my own PSU with one requierement in mind: build it like a tank. Back in the 1950s they were used in computers, calculators, and laboratory equipment. A flexible power supply for Nixie tubes. Module is designed as switching DC/DC step up converter. 5V at up to 1A at ~85% efficiency for older digital logic such as 74141 Nixie drivers (compare to about 40% efficiency if a 7805 is used) 3.3V for modern digital logic (microcontrollers, etc) High-voltage DC-DC converter can be shut down digitally to save power; Can be used with many different power inductors, depending on desired output power: You can use a smaller inductor, but I found the toroidal to have excellent parameters. This is second version of the Nixie Tube Driver project . It uses commercially available transformers How to Control a Nixie Tube With an Arduino: A Nixie Tube is a Neon gas-filled tube, that has a wiremesh anode with various cathodes shaped like numbers or symbols. I wanted to produce a Nixie display using easily obtainable parts (well… except for the Nixies), and at the same time keep the parts count low. NCH6100HV high voltage power supply module is miniature step-up DC-DC converter with high efficiency and low heat operating from 12 to 24VDC input, with an output of 85 to 235VDC set by a precise potentiometer. The work on this device is only allowed to competent authorized persons with the proper electrical qualification! 22 high-voltage outputs for nixie cathodes. Example code available for Arduino. This project is a HVPSU (High-Voltage Power Supply) that generates up to 220V from a 12V input. Multiple drivers can be connected in series. Prepared libraries for use in your own High Voltage Power Supply for Nixie Tube Projects Overview A completed unit. Output up to 200V. It’s astonishing that there are so many nixie tube enthusiasts out there, yet there is no good solution for the most critical part of a nixie circuit: the high voltage supply.
