Essential Info

Intermatic offers a wide variety of power packs in various wattages and control options. The Intermatic ML121RT 12-Volt Low Voltage Mechanical Timer Power Pack allows you to connect up to 121 Watts of low voltage lighting, typically for hardwired outdoor low voltage lighting systems. The power pack features keyhole cutouts that provide a surface mount installation for ease of operation. The power pack plugs into a GFCI rated outdoor outlet and low voltage lighting connects to the Power Pack via a hardwired, screw-down terminal connection; use 16 AWG wiring (at a minimum) for low voltage outdoor cable. A convenient dial with adjustable trippers makes setting the on/off times a breeze. All power packs are certified for safe operation and long life
