Description
The Intermatic DTAV40Q-M is a heavy-duty defrost timer engineered for refrigeration systems, walk-in coolers, freezers, and HVACR environments — designed to automate defrost cycles for electric heat, hot gas, or compressor shutdown systems. Rugged, versatile, and built for reliability, this timer brings precise, programmable control to refrigeration defrost operations.
Key Features
-
Auto-voltage 120-240 VAC compatibility: Automatically adapts to 120 V or 240 V AC supply, making it suitable for a wide range of refrigeration and HVAC charging systems.
-
High load capacity — 40 A / 2 HP rating: Handles heavy resistive or motor loads, ideal for compressors, defrost heaters, or refrigeration equipment requiring powerful switching capacity.
-
Programmable defrost cycles: Programmable in 15-minute increments up to a maximum of 23 hours 45 minutes. Minimum ON/OFF time is 15 minutes, making it flexible for short or extended defrost cycles.
-
Quartz-driven real-time clock with self-recharging battery backup: Keeps accurate time and retains programming for up to 72 hours during power outages — ensures reliable defrost scheduling even during power loss.
-
Fail-safe termination options: While defrost cycles primarily rely on timer-based scheduling, the system allows for optional termination via temperature or pressure switches — the timer acts as a safety backup if automatic termination fails.
-
LED indicators & moisture-resistant board: Built with a conformal-coated circuit board for moisture resistance, and LED indicators for defrost and refrigeration cycles for easy status monitoring.
-
Easy installation & flexible mounting: Designed for bracket or wall mounting, fits into existing enclosures without the need for special tools. Wiring supports #8 AWG conductors via box-lug terminals.
