Nemtek Merlin Stealth M28S-X Energizer

Th two-zone Merlin Stealth energizer is a powerful range of energizers for the residential to high-end residential market and is a cost-effective solution, where you need more than one zone.

Separation of the fence into zones allows for easy identification of the zone affected by fence faults or tampering. Nemtek’s smart design allows the maximum amount of energy to be transferred to the zone that needs it. However, the combined energy of the two zones will not exceed the legal maximum permitted. These energizers can be controlled by a tag and/or a keypad.
