![]() The other benefit is that it will provide a constant voltage to the EDC pulse module. You may need to increase capacitor uF to compensate for a loss of energy output. By dropping the input voltage on the EDC module using the buck converter this will decrease the output voltage from the coil. 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. Many ignition coils output 20Kv+ which is too high, but you should test with a load (ideally a fence line load of 500 Ohms. Using the buck / booster converter will give you some control over the coil exit output voltage. These can easily be purchased from Tindie or your usual source. Supply voltage: Typically 12v DC (5v to 12v depending on coil / transformer)Ĭurrent consumption: Varies depending on the coil / transformer, can be as little as 10mA, typically around 50mA to 100mAĬonnect a suitable low cost step up/down (buck / boost) or step down / buck converter between the battery and the EDC power input module. Three Layer varnish for increased moisture resistance. Input voltage reverse polarity protection. All marked on the module.Įasy to connect an on/off switch (not included) Logical very easy connection of other required components. LED for pulse indication supplied on flying lead connector for easy mounting into any enclosure. The DC source can be a 12v car battery or power adaptor etc. (The module will not allow a continuous spark to be generated.)ĭC input for 12v down to 5v depending on the coil (the lower the input voltage the lower the output voltage and energy*). You should aim for an absolute maximum 1Hz (one pulse per second) and typically one pulse every 1.25 seconds. This is useful as different size coils / transformers can decrease or increase the pulse frequency. This allows you adjust the frequency of the pulse. High voltage pulse generation with minimal pulse frequency adjustment (0.6hz to 1.2hz apprx.). Attach to a coil / transformer and suitable capacitor. 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.ĭO NOT OPERATE or APPLY POWER WITHOUT THE CAPACITOR, COIL / TRANSFORMER or LOAD (ELECTRIC FENCE LINE) BEING CONNECTED. Optional step down or step up / step down converter (Recommended)* 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.Ī decent size and thickness earth rod / bar (earth rod, metal fence pin, rebar, heavy duty tent peg, etc. But for a certified application specific transformer contact me.Ī motor run / fan start capacitor recommended 0.5uF to 3uF (5uF maximum) with a rated voltage of 400v to 450VAC.ĭepending 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. It can also be used to repair a damaged or defective energiser.Īn ignition coil / transformer - you can use any such as those found in mopeds, scooters, cars etc. (there are thousands of unused ignition coils around from old or damaged vehicles). 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. ALL MODULES ARE TRIED AND TESTED BEFORE THEY ARE SHIPPED. However the additional components required are cheap and readily available and can be purchased from your usual components supplier. This listing is for the (one) module only. Can be used for multiple applications including building or repairing their own electric fence energiser / high voltage pulse generator. This PCB module is intended for competent qualified professionals to generate high voltage electrical pulses. ![]() ![]() If you do use it to make your own energiser, you must observe and obey the laws in your country relating to the use of such equipment.
