Overview
The Intermatic K1122 is a relay-type photocontrol designed for outdoor lighting applications requiring 210-240V AC operation. Part of the K1100 series, this unit provides instant on/off switching with a 1800W tungsten and 1800VA ballast capacity. The adjustable stem and swivel mounting make it suitable for pole-mounted and wall-mounted fixtures in street, parking lot, pedestrian, and landscape lighting systems.
