(Battery is for memory backup only, not for device power control.) 4) Optimized copper trace design for extended lifespan, mode function, real-time switch status monitoring. 5) Compact, lightweight, multifunctional design for easy installation. Programming example: "Turn on at 6:00 AM and off at 7:00 AM; on at 11:00 AM and off at 12:00 PM; on at 6:00 PM and off at 12:00 AM." Up to 16 programmable on/off cycles per day or week. Minimum interval: 1 minute. Maximum interval: 168 hours. Supports daily or weekly repeat cycles. Technical specifications: - Display: LCD - Power consumption: <1W - Net weight: 80g - Operating temperature: -20°C to +55°C - Operating voltage: 220-240VAC, 50-60Hz - Custom voltage options: 12V, 24V, 36V, 48V, 110V, 380V - Time range: 1 minute to 168 hours - Timing accuracy: 1 second per 24 hours at 25°C - Switching capacity: 16 on/off cycles per day or week - Dimensions: 60 x 60 x 32 mm - Installation: Screw or connector type - Complies with standard: GB/T14536.1 Applications: 1) Timer for charging mobile phones, car batteries, and electric vehicles; time-controlled switching. 2) Suitable for electric water heaters, heaters, rice cookers, humidifiers, oil-filled radiators, air purifiers, and other household appliances to enable automatic operation. For example, set the water heater to provide hot water at a desired time each morning. 3) Ideal for use in areas with time-of-use electricity pricing to take advantage of lower off-peak rates. 4) Used for lighting control of street lamps, advertising boards, distribution panels, building facades, and exterior lighting with scheduled on/off times. Enhances visibility while reducing energy costs. 5) Suitable for scheduled garden irrigation, periodic drainage, and aquarium systems. 6) Applicable for synchronized switching of surveillance systems, school public address systems, and similar timing applications. The device supports up to 16 on/off groups per day (16 on and 16 off operations). Direct control wiring required. Controlled appliances must operate on single-phase 220V power. Load capacity: resistive load up to 16A, inductive load up to 8A. Important notes: - The "switch" controls only the live wire and must not be connected to power or current terminals directly. - This timer does not provide voltage conversion. It cannot convert AC220V to DC12V or any other output voltage. Note: All data measured manually. Allow 1–3 cm size variation due to lighting and temperature differences.
