THC15A Microcomputer Time Control Switch

Product Overview

Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, THC15A Microcomputer Time Control Switch is designed for automatic time-based control in distribution boards, control cabinets and electrical panels. It allows users to set daily or weekly operating schedules, helping connected equipment start and stop automatically according to preset time periods.​

Compared with mechanical time switches, THC15A provides more flexible programming, clearer digital display and easier schedule management. It supports 28 groups of ON/OFF settings, making it suitable for electrical systems that require multiple switching periods within one day or one week.​

With compact rail-mounted structure, manual switch function and power reserve design, THC15A is suitable for lighting control, pump control, ventilation systems, commercial facilities, public buildings and industrial automation applications where stable automatic timing control is required.​

Main Features

1. Microcomputer control: Digital timing control enables accurate automatic switching according to preset time programs.​

2. 24-hour and 7-day timing range: Supports both daily cycle control and weekly schedule control for different electrical operation requirements.​

3. 28 groups ON/OFF settings: Multiple switching programs can be configured to control equipment during different working periods.​

4. Keypad and digital display: Clear display and button operation make time setting, program checking and adjustment more convenient.​

5. Multiple rated current options: Available in 16A, 25A and 30A specifications to match different lighting and equipment load requirements.​

6. Manual switch function: The manual control mode allows temporary ON/OFF operation when on-site adjustment is needed.​

7. Power reserve design: The built-in reserve function helps maintain timing data when the power supply is interrupted.​

8. Rail-mounted installation: Compact DIN rail design is suitable for distribution boxes, control panels and electrical cabinets with limited space.​

Application Scenarios

1. Lighting control systems: Used for automatic switching of street lights, shop signs, factory lighting, corridor lighting, warehouse lighting and public area lighting.​

2. Pump and water supply control: Suitable for timed operation of water pumps, circulation pumps, drainage pumps and irrigation systems.​

3. Ventilation and HVAC systems: Applied in exhaust fans, cooling fans, air circulation equipment and ventilation systems requiring scheduled operation.​

4. Commercial building management: Used in offices, shopping malls, hotels, schools and public facilities to reduce manual operation and improve energy-saving control.​

5. Industrial automation equipment: Suitable for auxiliary machines, small production equipment, conveyor systems and control cabinet applications.​

6. Agricultural and garden systems: Applied in greenhouse ventilation, garden irrigation, breeding equipment and outdoor electrical control systems.​

7. Energy-saving electrical projects: Helps electrical loads operate only during required time periods, reducing unnecessary standby operation and improving management efficiency.
