Overview
The Tork 2005 photocontrol is a professional-grade turn-lock mounted photoelectric control designed for automatic lighting management in commercial and industrial environments. With a 1000W tungsten and 1800VA ballast load capacity, this unit provides instant-on response and delayed-off functionality for efficient energy management. The turn-lock receptacle design ensures quick installation without rewiring, making it ideal for retrofit applications and new construction.
Key Features
- Turn-Lock Mounting: Secures directly into standard locking-type receptacles for tool-free installation and removal
- Instant ON / 3-5 Seconds OFF: Rapid response to light changes with programmable delay-off to reduce nuisance cycling
- 360 Joule MOV Surge Protection: High-capacity surge arrestor protects connected loads from voltage spikes
- CdS Light Sensor: 1/2-inch epoxy-coated cadmium sulfide cell with proven sensitivity and durability
- Fail-Safe ON Mode: Defaults to on position if control fails, ensuring continuous lighting for safety
- Standards Compliant: Meets UL773, ANSI C136.10, and EEI NEMA requirements for roadway and area lighting
