Digital Timer THC15A 220V

Description

Product Description: THC15A Digital Weekly Programmable Timer Switch The THC15A is a microcomputer-controlled, 7-day digital programmable time switch designed for automated control of electrical circuits. Built into a compact, 35mm DIN-rail mountable housing, it features an LCD digital display that allows users to pre-set up to 16 distinct “ON” and 16 “OFF” configurations per day or week. It runs on standard 220V–240V AC power and includes a built-in backup battery, ensuring its internal clock keeps perfect time and retains your custom programs even during a total mains power outage. Key Features Time Management: 7 days / 24 hours weekly programmable schedules. Capacity: Up to 16 ON and 16 OFF programs repeating daily or weekly. Load Rating: Typically equipped with a high-capacity internal relay (rated for 16A resistive loads). Power Reserve: Built-in rechargeable lithium battery protects memory settings during power cuts. Compatible Mechanisms & Machinery The THC15A operates as an automated electronic switch. While it can directly switch lower-power equipment up to its rated amperage (usually 16A resistive / 8A inductive), it is commonly paired with magnetic contactors to safely run larger industrial machinery. It is highly compatible with the following systems and mechanisms: 1. Lighting and Illumination Mechanisms Compatible Systems: Streetlights, neon advertising signs, warehouse high-bay lights, parking lot illumination, and security floodlights. Application: Automatically turns large lighting arrays on at sunset and off at sunrise, or on a fixed daily routine to cut down electricity waste. 2. Agricultural & Irrigation Equipment Compatible Mechanisms: Submersible water pumps, automated garden sprinklers, greenhouse misting systems, and hydroponic nutrient pumps. Application: Runs watering cycles at exact times of day (e.g., 30 minutes every morning and evening) without requiring manual intervention. 3. HVAC & Ventilation Systems Compatible Mechanisms: Exhaust fans, industrial ceiling fans, ventilation blowers, and air conditioning units. Application: Schedules ventilation systems in factories or commercial buildings to run only during working hours or specific intervals to maintain air quality. 4. Commercial & Domestic Water Heaters Compatible Mechanisms: Industrial geysers, boilers, and large domestic water heating tanks. Application: Prevents heavy heating elements from running 24/7 by restricting operation to peak usage windows (e.g., turning on an hour before a factory shift starts). 5. High-Power Machinery (Via AC Contactors) Compatible Mechanisms: Industrial air compressors, battery charging stations, conveyor belts, and heavy production machinery. Application: If a machine draws more than 16 Amps or uses a heavy-duty inductive motor, the THC15A is wired into the control circuit of an external AC Contactor. The timer safely tells the contactor when to flip the heavy physical switch.
