The energiser is reliable and has versatile applications: It can be powered by a 230 V connection, a 12 V battery or a solar panel.

Why choose an electric fence energiser from VOSS.farming?

We have 35 years experience in the electric fence business and know how important it is to use a reliable energiser. That's why we sell exclusively high-quality branded devices made in Germany – by VOSS.farming. Naturally all our energisers fulfil the stringent European safety standard EN60335. Because we're convinced of the quality, reliability and safety or our devices, we're happy to offer you a 3-year warranty on all our energisers. And if you should still have any problems or questions, our professional workshop and our advice team will be happy to help you.

Here's where the VOSS.farming "Helos 4" scores points:

The 9.600 Volt shock strength and the 3.2 Joule shock power ensure that the fencing is reliable and secure. The device can be powered by mains power, battery or solar panel, and is suitable for a wide range of purposes. A mains adapter is included, so that the fence energiser is ready for immediate use. Deep discharge protection protects the battery. The "Helos 4" is equipped with a modern power saver system, ensuring that the power consumption adjusts automatically to the condition of the fence. It has a modern LED fence and battery monitor, which allows immediate recognition and remedying of problems with the supply or the fence.

The "Helos 4" is suitable for  fence lengths up to 24 km without vegetation. Even with moderate vegetation, this device ensures high security for your animals. Our all-round star is suitable for many different types of animals. It protects chickens, cows, and horses, and also reliably deters wild animals like deer and stags.

The "Helos 4" is notable for having 3 different power supply options, for its long life, and its excellent value for money.
