Power supply voltage: 220V/12V Time error: 1 second/24 hours at 25℃ Time cycles: 17 on/off cycles Display unit: LCD Power consumption: <2W Power-off memory: 60 days Internal battery: 1.2V 40mAh rechargeable battery Time interval: 1 minute ~ 168 hours Ambient temperature: -20°C ~ +55°C Dimensions: 60*60*32mm This product can automatically turn on and off the power of various electrical appliances according to the time set by the user. It is widely used in power control products for production equipment, street lights, light boxes, neon lights, warehouse ventilation and dehumidification, agriculture, and broadcasting. It has 17 preset time groups: Preset time switching: e.g., turn on at 8 AM and turn off at 12 PM (set the switching time according to your needs). Once set, you can choose to cycle the switching according to the week, a setting for infinite looping. High-quality and powerful components: Eight-bit microcontroller chip: This packaging technology is fixed on the PCB board, ensuring stable performance and strong resistance to electromagnetic interference. 16A relay, sufficient load capacity for increased safety and stability. Built-in high-quality button cell battery, retains data for 60 days after power failure, no reset required. High load capacity: Resistive load 3500W (220V) for devices that directly consume electrical energy, e.g., electric stoves, rice cookers, induction cookers. Inductive load 850W (20V) for devices with high starting current, e.g., washing machines, air conditioners, refrigerators. Motor load 700W (220V) for lighting loads. Lighting load 1200W (220V) for lighting.
