Featuring a wide input range (8-32V), precision voltage adjustment, and comprehensive protection mechanisms, it delivers efficient, reliable high-voltage power for advanced electronic projects and experimental setups. ## Description Description: High Voltage Boost Module Module Properties: Non-isolated step-up module Input Voltage: 8~32V input(the default is 10~32V input.) Input Current: 5A (Max) Quiescent current: 15mA (12V liter 50V, the output voltage, the higher the current will increase too quiet) Output Voltage: +45~390V continuously adjustable (default output ±50V) Output Current: 0.2A Max(with input, output pressure related,the higher the output voltage, output current is smaller) Output Power: 40W (Peak 70W) Working Temperature: -40 ~ + 85 degrees (ambient temperature is too high, please enhance heat dissipation) Operating frequency: 75 KHz Conversion efficiency: up to 88% (efficiency and input and output voltage, current, pressure-related) Short circuit protection: Yes. Over current protection: Yes. (Input current exceeds 4.5A, reducing the output voltage) Over voltage protection: Yes. (Output voltage exceeds 410V, lowering the output voltage) Input reverse polarity protection: Yes (non-self-healing, reverse burning fuse, try not reversed.) Installation: Four 3 mm screws Wiring: free welding output terminals Size(L*W*H):60 x 50 x 20 mm Package Included: 1 x Booster Module Review: Though this power supply says it is 45-390 Volts, it actually delivers two equal outputs: +45 to +390VDC and -45 to -390VDC at the same time, a max differential of 780 volts. The two outputs track, more or less. A precision 25-turn pot sets the output voltage. Output is not floated, but is tied to the common input ground. The two 10-uF aluminum electrolytic caps on the two outputs are rated 400V, so it is probably best to operate this thing at 300V or less. If you are using only the positive (+) output, it might be a good idea to lightly load the minus (-) output to keep it from floating up too high and popping the cap on the negative rail - may be unnecessary - just good HV practice. The unit does have bleeder resistors on the output, so that when you turn it off, the output voltages drain off within 10 seconds or so to safe levels. This is a regulated switching power supply. Output voltage does not track input voltage, but rather is independent of input voltage so long as supply voltage is sufficient. One reviewer stated that he wanted high voltage and 700 mA for plating; assuming 300 VDC or so, that would be 210 watts, well above the rated and fairly respectable 40W. Another (3-star) stated that it took him a while to figure out that output voltage is adjusted by a tiny screw. Please, people. This product is for folks who have a basic familiarity with electronics or aren't afraid to do a little googling to figure out what they may not know. Yes, documentation could be a little better, but then they'd have to charge more. The trimpot on this unit is a look-alike of the 25-turn Bourns unit; just the trimpot here in the US runs $14.66. Go figure. I recommend this unit, plan to use it to supply +200V to power an old 6E5 fluorescent "tuning eye," bought on eBay, if you remember those from old AM radios. I think it will do just fine. Just don't lick the output when it's set to 300V to test if it's on. Ouch! Use a voltmeter instead. If you don't have a voltmeter, buy a voltmeter first. If you aren't sure what a volt is, maybe you should start with lower voltages. 1.5 volts, for instance. Buy a AA battery and measure that. Electricity and electronics isn't that hard. But learn a little before you start fiddling with hundreds of volts. Learn, live long and prosper. In that order. Review: Works well with good regulation at 250v under 100mA. The transformer gets hot after 30 minutes.

See the gm measurement for a 6L6 below ### ⭐⭐⭐⭐⭐ Review *by N***E on 4 October 2023* I'm not sure if this is standard but my board has an extra capacitor and output for a negative rail! I measured a maximum 815VDC between them! That's a lot of voltage from such a tiny package :) ## Frequently Bought Together - DEVMO 8-32V to 45-390V DC-DC High Voltage Boost Converter ZVS Step-up Booster Module - High Voltage DC-DC Boost Power Supply Converter Module for Vintage Vacuum Nixie Tube, Magic Eye 6E2 Level Indicator 9V-12V DC Input, 80V-380V DC Output (Green) - 6 PCS/LOT NOS Vintage NEON Nixie Tube IN-12B (Analog B5991) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/256018763-8-32v-to-45-390v-dc-dc-high-voltage-boost](https://www.desertcart.sg/products/256018763-8-32v-to-45-390v-dc-dc-high-voltage-boost) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-04-23*
