Description
The Nemtek Merlin 4 is a powerful, reliable and user‑friendly electric fence energizer designed for both residential and light commercial perimeter security. Built for durability and convenience, it delivers a strong 3.7 Joule output with up to 8 000 V open‑circuit voltage — enough to secure moderate‑length fence lines while offering stable, consistent performance.
Equipped with a built-in rechargeable battery (plus mains power), the Merlin 4 ensures that your fence remains active even during power outages — offering around 24 hours of standby protection on a fully charged battery.
What sets the Merlin 4 apart is the included keypad control: you can install the unit near the fence while placing the keypad up to 100 m away — making arming, disarming or adjusting settings more convenient. The keypad gives you flexibility: adjust output voltage, toggle gate or siren outputs, switch between high/low voltage modes (e.g. lower output if children or pets are near), and bypass alarm outputs when needed.
