High Voltage Pulse
Arc Pulse Ignition
Ignition Coil Module

Features:

Made of quality material, which is durable and for long time use.

When it operate in the air, no crackling sound, but the temperature is very high, can easily ignite paper, plastic, even very fine wire.

For middle school science experiments, electronic instruments, negative ion generator, science and small production.

The transformer primary has two windings, one main winding and one feedback winding.

The two thick and fine coiled copper wires are the positive poles, which are respectively the main winding tail and the feedback winding head, connected to the positive poles of the power supply.

Note:

The transformer's high-voltage winding is wound on the inner layer, which is a segmented framework and encapsulated by resin. The low-voltage winding is on the outer layer. Please do not mistake the winding way of the high-voltage winding and low-voltage winding of this transformer.

High voltage ac transformers are very hard to find. I drove this using a 20v square wave from an h-bridge driver and it did just fine lighting a 5' neon tube. It worked well from 20KHz to about 40KHz with no resonance. Perfect for small plasma displays and neon drivers. Wish there were bigger versions available, but for what it is, it definitely a real find.

Very Special Applications only, high voltage application.

Unfortunately, I had been busy and didn't get around to messing with until it was too late to return it. I researched everything I could think of to get it working, but I'd guess it's fragile appearance is more than appearance. My fault for waiting so long to check it out.

Poorly made. Not a solid build. When being use it shakes and after a few days fall apart.

I think it was DOA, but it's definitely D now.

It was smaller than I thought but seams to do the job!
