This device is capable of harmful or lethal electric shock if handled with negligence. By purchasing, you accept responsibility for the safe handling and operation of high voltage electronics.

What is it?

This device, born by the need for larger and more spectacular arrays of large nixie tubes, is a high voltage DC-DC converter. It is not just any bargain bin nixie power supply however; this boost converter will easily do 200 milliamps of high voltage (continuously adjustable from 170-190 volts) from anywhere between 12 to 24 volts DC in. Without breaking a sweat.

Why?

Long story short, I created this power supply to bridge a niche gap in the nixie tube market. There are several neon enthusiasts out there that have expressed the desire for a single high power, high voltage solution as opposed to using many small power supplies.

Specifications

The rated input-output characteristics are as follows:

Input: anywhere between 12 to 24 volts DC (no jumpers required, auto detecting)

Output: adjustable between 170 to 190 volts DC

Rated continuous high voltage output current: 200 milliamps

Minimum 91% efficiency at 12 volts in (efficiency increases at higher input voltages)

Recommended AC-DC adapter specifications: 50 watts +, UL rated

Each power supply is painstakingly hand assembled using brand new OEM components from Digikey and burn-in tested for 4 hours at rated output.

What am I paying for?

This design is built on high performance, genuine components and boasts several useful features:

• Texas Instruments TPS40211 current mode boost controller, with enable/disable for turning high voltage on/off using an external switch or micro-controller

• High TG (170-180) FR4 boards, 2oz copper weight, ENIG finished with matte green soldermask and gold silkscreen. Boards are fabricated with rigorous quality control standards.

• High voltage, high current HiPerFET™ MOSFET from IXYS (Littlefuse)

• SiC (silicon carbide) automotive grade Schottky diode from STMicroelectronics

• High ripple current, long life 105°C electrolytic capacitors from Panasonic and Rubycon

• High current, parallel torodial inductors with Sendust cores from Bourns

• C0G/NP0 ceramic capacitors for signal, X7R/X7T for decoupling and bulk power

• Input and output wire-to-board terminal blocks, 5 amp rated input barrel jack (2.00mm ID 5.50mm OD)

• Socketed, replaceable 6.3 amp fast-blow fuse

• Trim pot for high voltage (continuously adjustable from 170 to 190 volts)

• Input filtering and surge suppression

Please note that no AC/DC adapters, screws, standoffs, wiring, or additional hardware is included with the sale of this power supply module.
