Switching relay UC. 1 changeover contact, potential-free 10A/250V AC, incandescent lamps 2000W. No standby loss. For installation and surface mounting. 45 mm long, 45 mm wide, 18 mm 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. Very low switching noise. By using a bistable relay, there is no coil power loss and no heating as a result, even when switched on. The relay contact can be open or closed when commissioned and synchronizes when first activated. This relay is not suitable for feedback with the switching voltage of a dimmer switch. Only use the ESR12DDX-UC, ESR12NP-230V+UC or ESR61NP-230V+UC relays for this purpose. The electronics have no power supply of their own and therefore no standby loss. The microcontroller is only activated when the control contact is closed, which switches the bistable relay in the correct direction. When the control contact is opened or the control voltage drops, it switches back.
