Supco UET240 Universal Adjustable Electronic Defrost Timer

Product Description

The Supco UET240 is a universal adjustable electronic defrost timer designed for use in refrigeration and freezer systems operating on 120 VAC at 50/60 Hz. Built with a solid-state design, it replaces mechanical defrost timers in a wide range of applications. The timer features an adjustable defrost frequency from 4 to 12 hours and an adjustable defrost time from 10 to 35 minutes, giving service technicians the flexibility to match the timer to the equipment's actual defrost requirements. The dust-proof case and quiet solid-state operation make it a reliable long-term replacement in commercial and residential refrigeration cabinets.

The UET240 is suited for residential refrigerators, reach-in coolers, freezers, and similar refrigeration equipment where a standard-size defrost timer is required. Its standard terminal configuration accommodates most common wiring connections without adaptation. The cycle advance button simplifies setup and testing during installation. No ground wire is required. The unit operates within a humidity range of 10 to 95 percent non-condensing and a temperature range of 32 degrees F to 135 degrees F, covering typical equipment cabinet environments.
