CAST Perimeter® 1200W DC Power Supply with Astronomical Clock and 3rd Party Control



The CAST Perimeter® Lighting DC Astronomical Input Transformer is a low voltage perimeter lighting 1200 Watt power supply designed to operate on a set program, or as part of an automated lighting solution to deter threats.

Two zone, dry contact closure (NO/NC) interfaces with third-party intrusion detection solutions to turn on/off lights. User-defined light control to deploy "Flash-Glare"™ feature to deter intruders.

Customized GPS on/off dusk to dawn control, days of the week programming.

Integrate with 3rd party perimeter detection systems using dry contact signals from cameras, motion, radar, laser, etc. to turn on/off lights to automatically activate, surprise, and disorient intruders without the involvement of on-site security guards!

High efficacy DC power, eliminates flicker, and produces crisp images that will reduce VMS storage and save money.
