• 【High 20A Current Capacity】 Handles 20A loads, ideal for heavy-duty devices like industrial HVAC or large irrigation pumps. 16 ON/OFF settings (1min~168h) automate factory machinery or farm lighting with ≤1s/day timing error.
• 【Multi-Voltage Compatibility】 Works with 12/24V DC (RVs, boats) and 110/220V AC (homes, factories). 1NO+1NC contacts control dual circuits, perfect for neon signs or aquaculture systems needing precise on/off cycles.
• 【3-Year Power Backup】 Built-in lithium battery retains settings during outages, critical for uninterrupted operation in commercial freezers or emergency lighting. -10~40℃ tolerance suits garages or warehouses.
• 【Easy DIN Rail Installation】 35mm standard size fits electrical panels. 10⁵ electrical life ensures durability in residential, commercial, or industrial use—no tools needed for setup.
