DHC15A/DHC20A: The Next Generation of Programmable Time Switches with Unmatched 3-Year Operational Autonomy
The DHC15A and DHC20A Programmable Time Switches represent a significant leap forward in the design and functionality of industrial and commercial timing control solutions. Engineered for applications demanding long-term reliability, complex scheduling, and minimal maintenance, these devices are built upon a foundation of exceptional energy efficiency and operational longevity. Their core architecture is designed to solve the critical industry pain point of frequent battery replacements and system downtime, establishing a new benchmark for set-and-forget automation components in control panels worldwide.
Revolutionary 3-Year Operational Autonomy and Unwavering Accuracy
The most defining feature of the DHC15A/DHC20A series is its groundbreaking 3-year working reserve time. This is not merely a battery backup but a complete operational autonomy, ensuring all programmed settings and real-time clock accuracy are maintained for three full years without primary power. This feature is invaluable for critical infrastructure, data loggers, and security systems where power interruptions are common, guaranteeing that the device resumes its scheduled operations seamlessly. Complementing this longevity is a remarkable timing accuracy of ≤2 seconds per day at 25°C. This high-precision quartz crystal-driven movement ensures that daily, weekly, or complex multi-year schedules execute with pinpoint reliability, preventing cumulative timing drift that can disrupt automated processes.
Unprecedented Programming Flexibility for Complex Control Logic
Moving beyond simple on/off cycles, this series offers sophisticated programming capabilities to handle intricate automation scenarios. With a time setting range from 1 minute to 168 hours (7 days), and a minimum setting unit of 1 minute, users can create highly granular schedules. The powerful 32 on/32 off program memory allows for the management of complex multi-time-segment operations throughout a week, ideal for applications like multi-stage industrial processes, energy management in commercial buildings, and sophisticated lighting control systems. Furthermore, the inclusion of an 18-times pulse mode opens doors for advanced functions such as testing sequences, periodic alarm triggering, or resetting other equipment at predetermined intervals.
Robust Hardware Designed for Demanding Electrical Environments
The DHC15A and DHC20A are distinguished by their robust switching capabilities, tailored to different load requirements. The DHC15A model offers a substantial resistive load capacity of 16A at 250VAC and a lamp load of 1000W, making it suitable for controlling lighting circuits, heaters, and general-purpose outlets. For more demanding applications, the DHC20A model steps up with an impressive 20A resistive load and 2500W lamp load capacity, enabling direct control of higher-power equipment such as large industrial fans, powerful heating elements, and significant lighting arrays. This robust contact design ensures reliable switching and a long electrical life.
Global Compatibility and Streamlined Integration
Designed for a global market, these time switches support a wide operating voltage of AC 110V/220V at 50/60Hz, making them universally compatible with standard power grids without the need for external adapters. Their compact form factor (81x36x66mm) and industry-standard DIN rail mounting (EN/IEC 60715) ensure effortless integration into any modern electrical enclosure alongside contactors, circuit breakers, and PLCs. With an operating temperature range of -10°C to +50°C and a low power consumption of 4.5VA (DHC15A) / 7.5VA (DHC20A), they are built to perform reliably in the challenging conditions typical of industrial and commercial settings.
In summary, the DHC15A and DHC20A Programmable Time Switches are not just components but comprehensive timing solutions. They empower engineers, facility managers, and system integrators to design highly reliable and intelligent automation systems for manufacturing lines, agricultural controls, public lighting, and building management, all while virtually eliminating maintenance concerns for years to come.
