7. Eltako ER12-001-UC
Wechsler potential-free 16A 250V AC, 230V LED lamps up to 200W, incandescent lamps 2000W. No standby loss. Rail-mounted device for installation on DIN-EN60715 TH35 mounting rails. Division unit 18mm wide, 58mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. Universal control voltage 8..230V UC. Low switching noise. Control indication with LED. Integrated freewheeling suppression diode A1=, A2= -. Safe isolation according to VDE 0106, part 101, therefore also usable as a coupling relay. By using a bistable relay, there is no coil loss and no heating even when switched on. The relay contact can be open or closed during commissioning and will synchronize on the first actuation. This relay is not suitable for feedback with the switching voltage of a dimmer switch. For this purpose, only the relays ESR12DDX-UC, ESR12NP-230VUC, or ESR61NP-230VUC should be used. The electronics have no independent power supply and therefore no standby loss. Only when the control contact is closed is the microcontroller activated, which switches the bistable relay in the correct direction. When the control contact is opened or the control voltage drops, it switches back. ER12-001-UC.
