Nemtek Energizer - Merlin M28S 8J 2Z | E-M28SV1

The Nemtek Merlin M28S (E‑M28SV1) is a powerful dual‑zone electric fence energizer delivering up to 8‑Joule class output (7.6 J at 500 Ω combined), designed for advanced residential, commercial, and high‑security perimeter installations. Its dual‑zone architecture allows the perimeter to be divided into two independently monitored fence zones, enabling rapid identification of fence faults or tampering while intelligently distributing energy without exceeding legal output limits. The energizer supports tag and optional keypad control, allowing flexible remote arming, disarming, and programming with support for up to four keypads, making it ideal for multi‑access sites. Built‑in fence and earth monitoring, two independent gate alarm inputs, alarm outputs, and compatibility with armed response radios or GSM modules, combined with lightning and surge protection, ensure reliable operation in demanding environments. Powered by 240 V mains with an integrated battery backup, and providing an open‑circuit voltage of up to 9.3 kV, the Merlin M28S is ideally suited for large estates, campuses, industrial facilities, and critical‑infrastructure perimeters requiring flexible, high‑power, dual‑zone electric fence control.
