Eltako Coupling relay KRW12DX-UC

1 potential-free switch 16A/250V AC with tungsten pre-contact. The pre-contact closes before the main contact, thereby handling an inrush current of LED lamps that occurs over a few milliseconds. Max. inrush current 500A/2ms. 230V LED lamps up to 600W, incandescent lamps 3300W. No standby loss. Rail-mounted device for installation on DIN-EN 60715 TH35 mounting rails. 1 modular 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. With the patented Eltako duplex technology (DX), the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50 Hz, thus drastically reducing wear. Simply connect the neutral conductor to terminal (N) and live to terminal 1(L). This results in a standby loss of only 0.1 watts. If the contact is used to control switching devices that do not switch at zero crossing, (N) should not be connected, as the additional closing delay would have the opposite effect. Universal control voltage 12..230V UC. Low switching noise. Control indication with LED. By using a bistable relay, there is no coil loss and no heating even in the switched-on state. The relay contact can be open or closed at startup and synchronizes on the first operation. This relay is not suitable for feedback with the switching voltage of a dimmer switch. Only use the relays ESR12DDX-UC, ESR12NP-230V+UC, or ESR61NP-230V+UC for this purpose. The electronics have no own 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.
