Nemtek Merlin Stealth M25s Electric Fence Energizer, is a powerful range that can be used for residential to high-end security needs and is a cost-effective solution where more than one zone is required. Separation of the fence into zones allows easy identification of the zone affected by fence faults or tampering. Smart design allows the maximum amount of energy to be transferred to the zone that needs it, yet 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. The energizers can be programmed to offer customised solutions.
