18 Series | Elevator 3-Phase Monitors with Trip & Restart Delays

The 18 Series monitors continuously track three-phase power lines to detect phase loss, phase reversal, and under-voltage conditions—even under regenerated voltage scenarios. Featuring adjustable trip and restart delays, these devices prevent nuisance tripping and short cycling in elevator traction, control, and safety circuits. :contentReference[oaicite:0]{index=0}

Powered by a microcontroller-based sensing circuit driving an electromechanical SPDT relay, these monitors automatically reset when faults clear. They require no neutral connection and support both Wye and Delta systems, mounting flexibly on DIN rails or surface panels. UL-recognized in the U.S. and Canada with optional gold-flashed silver contacts for low-current applications. :contentReference[oaicite:1]{index=1}
