2. สินค้าหมดview

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.

3.1. การติดตั้ง

The Eltako S2U12DDX-UC is designed for DIN EN 60715 TH35 support rail mounting. It occupies 1 division unit (18 mm wide, 58 mm deep).

1. Ensure power is disconnected at the main circuit breaker before installation.
2. Mount the device onto a standard DIN rail.
3. Connect the N conductor to the (N) terminal.
4. Connect the L conductor to 1 (L) and/or 3 (L) for the respective channels.
5. For centralized control, connect the control input (+A1) for central ON or OFF with priority. The supply and control voltage for central control is 8 to 230 V UC.
6. ตรวจสอบให้แน่ใจว่าการเชื่อมต่อทั้งหมดแน่นหนาและถูกต้องก่อนที่จะเปิดกระแสไฟฟ้าอีกครั้ง

3.2. Initial Configuration - Language Setting

After applying power for the first time, the language selection menu will appear.
