Energized conduction is not delayed, meaning the switch does not operate on power-up delay; instead, power failure is delayed at energization so the switch function to keep loads active for the preset time. This makes it ideal for controlled shutdown, fan overrun, or safety buffer operations. Knob-adjustable time delays from 0.03 to 10 minutes allow flexible timing control without special tools. Users can fine-tune delay settings directly on the unit for different scenarios, such as gradual power-down, staged equipment stopping, or timed lighting, improving operational convenience. Model Name: QD-072 delay on break timer is designed for precise control in automation, lighting, and industrial circuits. Compact and easy to integrate, it serves as a reliable replacement module for existing systems, offering stable performance and long service life in demanding applications. Wide input voltage 18-240 VAC or DC with 50/60 Hz frequency compatibility supports use in many regions and systems. The maximum 1.5A output current is suitable for low-power motors, lamps, relays, and control circuits, ensuring stable switching performance while protecting connected components.
