Nemtek Energizer - Merlin Stealth M18S 8J 1Z

The Nemtek Merlin M28S is a powerful dual-zone electric fence energizer designed for medium to large residential estates, small commercial sites, or light agricultural perimeters. It delivers up to 8 Joules total output energy (approximately 4 Joules per zone at typical loads) with independent monitoring and control of two zones—ideal for segmented fencing or separate areas requiring precise fault detection.

Key Features:

• Dual Independent Zones — Two separately monitored zones; each can be independently set to high/low voltage or on/off modes
• 8 Joule Total Output — Strong performance for longer or more demanding fences; maintains high voltage even with moderate vegetation or load
• LCD Keypad Included — Plug-in LCD keypad for easy on-site programming (voltage, pulse rate, day/night modes, alarm settings) and viewing real-time fence/battery status, faults, and events
• Mains with Battery Backup — 220–240V AC mains operation; supports 12V 7Ah battery (space included) for reliable runtime during power outages
• Alarm & Monitoring — Detects fence faults (short/open), earth tamper, low battery, AC fail; includes siren/strobe outputs, gate/tamper inputs, internal beeper
• Adaptive Power Technology — Optimizes voltage output to reduce arcing and false alarms while maximizing fence performance
• Durable & Protected — IPx4 weather-resistant enclosure; lightning/surge protection; overload/short-circuit safeguards
• Safety & Compliance — IEC 60335-2-76 compliant; walk-test mode; retained settings during power loss
• Expandability — Optional remote/tag compatibility for advanced control; solar upgrade possible
