TORK

3G Electric supplies TORK timer switches in three main types: digital electronic timers, electromechanical timers, and spring-wound mechanical timers. Digital models, like the EWZ120 and WFTU40, offer 7-day programming with astronomic functionality for automatic daylight adjustment. Electromechanical timers use synchronous motors for precise timing. Spring-wound timers, such as the A512HW and C530M, operate without external power and are suitable for simple on/off cycles. These timers are available in SPST, SPDT, and DPDT configurations, with voltage ratings from 125V AC to 277V AC.

Astronomic functionality in TORK digital timers, such as the EWZ120 and WFTU40, automatically adjusts the on/off times based on the time of year and geographic location. This feature calculates sunrise and sunset times, allowing lighting schedules to follow natural daylight patterns without manual reprogramming. It is useful for outdoor lighting control in parking lots, signage, and building exteriors, reducing energy consumption by ensuring lights operate only when needed.

Yes, TORK photocells like the ZTL480 are designed for high-voltage outdoor applications. The ZTL480 is a turn-locking photocell rated for 347-480V AC with a surge capacity of 510 J at 480V AC. It features a twist-lock mounting for secure installation in outdoor lighting fixtures. These photocells are suitable for controlling streetlights, parking lot lights, and area lighting where reliable dusk-to-dawn operation is required.

TORK spring-wound timers, such as the A512HW and C530M, are mechanical devices that use a spring mechanism to time intervals from minutes to hours. They do not require external power to operate, making them suitable for applications where power is intermittent or for simple countdown tasks. Digital timers, like the EW101B, use electronic circuits for precise programming, offering 7-day schedules and astronomic features. Digital timers require a constant power supply and provide more flexibility for complex scheduling.

TORK pool lighting transformers, such as the TPX300S, are designed primarily for pool, spa, and landscape lighting. They convert 120V AC input to 12-14V AC output with a maximum power rating of 300 W. While they can be used for other low-voltage lighting applications within the same voltage and power range, their stainless steel enclosure and specific output voltages are optimized for outdoor wet locations. Always verify that the transformer's specifications match the load requirements of the lighting system.

TORK timer switches are available in surface-mount and wall-switch styles. Surface-mount models, like the EWZ120 and EW101B, are designed for installation on junction boxes or panels, suitable for industrial or outdoor environments. Wall-switch models, such as the SS703ZA, fit standard electrical boxes and include options with or without wall plates. Some models offer indoor or outdoor ratings, with enclosures made from plastic, polycarbonate, or stainless steel for durability.
