2. Produktas baigtasview

The Eltako S2U12DDX-UC is a 2-channel programmable clock designed for DIN rail mounting. It features two potential-free contacts (1+1) rated at 16 A/250 V AC. This device supports LED lamps up to 600 W and incandescent bulbs up to 2000 W. It includes an Astro function for automatic switching based on sunrise/sunset, an illuminated display, and a power reserve of approximately 7 days without battery.

Thanks to patented Eltako-Duplex (DX) technology, the normally potential-free contacts can switch 230 V AC 50 Hz, significantly reducing wear. This is achieved by connecting the N conductor to terminal (N) and L to 1 (L) and/or 3 (L), resulting in an additional standby loss of only 0.1 W. The use of bistable relays eliminates coil power loss and heating when switched on.

Up to 60 memory locations are freely assignable across the channels. The device includes automatic date and summer/winter time changes.
