Designed for intermittent use with precise arc discharge control (10-20mm), this set of five compact modules features 100mm wiring for easy integration. Perfect for advanced electronics experimentation, it balances raw power with essential safety features to protect your investment. ## Description description please notice: the high-voltage module should avoid the use of electricity in high voltage no-load . (Power must be adjusted to a suitable distance to the high-voltage output line , battery capacity is proportional to the distance and the use of the high-pressure arc ( not a voltage as high as possible , you must provide enough current ) . Experimental test of the arc distance from short to long , Do not exceed the maximum arc distance electricity, energy can not be released due to high pressure , can easily damage the module. ) Work: intermittent , continuous work does not allow more than 1 minute and the output side does not allow shorting . Improper voltage and long working hours easily damaged module Package included: 5pcs ## Features - ★input voltage: DC 3 V to 6 V.

I need them to be longer than they currently are.** A: Strip the outer end of the wire about 5mm and solder on longer wires. Then heatshrink the joined part for insulation. **Q: is the output a ground and a high positive or high negative, or is the output a high negative and positive?** A: i beleive it is 3 volts dc to an inverter with high volts AC out not DC out **Q: Is the output voltage ac or dc?** A: AC. Probably around 40 000V peak to peak. Low amps. **Q: How can it be 400kv if the output leads are only 1 inch apart and use ordinary 250v insulation? if it was more than 25kv it would just arc the leads** A: Well, first of all, that's not ordinary insulation. I didn't test it, but it looks like kynar. The maker used good output wiring. I'm not going to back his claim of 400KV, because I personally have not taken one of the units into my lab and measured it, but I know a good bit about HV. Don't assume that the breakdown characteristics of air are linear. They're not. Under normal kitchen table conditions, you can draw 4 inch sparks from a 20kv source. Once a plasma conduction path is established, it is self-sustaining as long as the current keeps it hot. ## Frequently Bought Together - DEVMO 5PCS DC 3v-6v to 400kV 400000V Boost Step-up Power Module High-Voltage Generator - 9V Battery Connector,10 PCS T-Type 9 Volt Buckle Connector Hard Plastic Shell Used in Student Experiment,or Other Equipment with Battery - AEDIKO 5pcs High Voltage Generator DC 6-12V to 1000kV Boost Step-Up Inverter Arc Pulse Generator Power Module High Voltage Transformer --- ## 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.co.uk/products/255350161-devmo-5pcs-dc-3v-6v-to-400kv-400000v-boost-step](https://www.desertcart.co.uk/products/255350161-devmo-5pcs-dc-3v-6v-to-400kv-400000v-boost-step) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-26*
