This PCB module is intended for competent qualified professionals to generate high voltage electrical pulses. Can be used for multiple applications including building or repairing their own electric fence energiser / high voltage pulse generator. This listing is for the (one) module only. However the additional components required are cheap and readily available and can be purchased from your usual components supplier. It's really simple to use. Attach to a coil / transformer and suitable capacitor. Apply power that's it. ALL MODULES ARE TRIED AND TESTED BEFORE THEY ARE SHIPPED.
Why did I make it?
To provide a low cost way to make your own electric fence energiser/ fencer using easily available parts, some you may even have lying around. (there are thousands of unused ignition coils around from old or damaged vehicles). It can also be used to repair a damaged or defective energiser.
What else you will require:
An ignition coil / transformer - you can use any such as those found in mopeds, scooters, cars etc. But for a certified application specific transformer contact me.
A motor run / fan start capacitor recommended 0.5uF to 3uF (5uF maximum) with a rated voltage of 400v to 450VAC.
Depending on the coil or transformer a 3uF or 4uF capacitor will give between 1.6 to 2+ Joules of exit energy respectively and the fence line output voltage will be dictated by the type of coil or transformer being used. This means you can make small low cost compact energisers for strip grazing / small paddock or containment areas to larger energisers covering many Kms of fence line.
A decent size and thickness earth rod / bar (earth rod, metal fence pin, rebar, heavy duty tent peg, etc. etc.)
An enclosure of your choosing.
Optional step down or step up / step down converter (Recommended)*
Optional (Recommended). When operational and powered from a battery it's worth adding a low battery alarm / low voltage disconnect between the battery and energiser so that your battery does not drain too low and become damaged from over discharge.
DO NOT OPERATE or APPLY POWER WITHOUT THE CAPACITOR, COIL / TRANSFORMER or LOAD (ELECTRIC FENCE LINE) BEING CONNECTED.
Features & Functions:
It's really simple to use. Attach to a coil / transformer and suitable capacitor. Apply power that's it.
High voltage pulse generation with minimal pulse frequency adjustment (0.6hz to 1.2hz apprx.). This allows you adjust the frequency of the pulse. This is useful as different size coils / transformers can decrease or increase the pulse frequency. You should aim for an absolute maximum 1Hz (one pulse per second) and typically one pulse every 1.25 seconds. (The module will not allow a continuous spark to be generated.)
DC input for 12v down to 5v depending on the coil (the lower the input voltage the lower the output voltage and energy*). The DC source can be a 12v car battery or power adaptor etc.
LED for pulse indication supplied on flying lead connector for easy mounting into any enclosure.
Logical very easy connection of other required components. All marked on the module.
Easy to connect an on/off switch (not included)
Input voltage reverse polarity protection.
Three Layer varnish for increased moisture resistance.
Dimensions: 100mm x 50mm x 20mm
Supply voltage: Typically 12v DC (5v to 12v depending on coil / transformer)
Current consumption: Varies depending on the coil / transformer, can be as little as 10mA, typically around 50mA to 100mA
Connect a suitable low cost step up/down (buck / boost) or step down / buck converter between the battery and the EDC power input module. These can easily be purchased from Tindie or your usual source.
Using the buck / booster converter will give you some control over the coil exit output voltage. Many ignition coils output 20Kv+ which is too high, but you should test with a load (ideally a fence line load of 500 Ohms. Fence tape / line manufacturers usually state Ohms per metre and there is no substitute for 'real world' testing) as line voltage will drop the greater the length of fence line used. By dropping the input voltage on the EDC module using the buck converter this will decrease the output voltage from the coil. You may need to increase capacitor uF to compensate for a loss of energy output.
The other benefit is that it will provide a constant voltage to the EDC pulse module. This means that as the voltage is relatively stable and constant,the EDC modules' output will be constant, which will make the energiser output always the same. Where as, when connected directly to a battery,the line voltage and energy that is fed to the electrified fence line will decrease as the the battery voltage drops, meaning reduced shock voltage / energy.
The EDC module will work from as little as 5v making it also usable for protecting plant borders / raised beds etc. against slugs and snails when used with a suitable small scooter/moped coil or transformer and appropriate fence line setup (any questions feel free to ask).
