Eltako ER61-UC

No standby loss. Suitable for flush 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 of 8 to 230 V UC. Very low switching noise. The use of a bistable relay means there is no coil loss and no heating even when switched on. The relay contact can be open or closed at startup and will synchronize upon the first activation. This relay is not suitable for feedback with the switching voltage of a dimmer switch. Only use relays ESR12DDX-UC, ESR12NP-230V+UC, or ESR61NP-230V+UC for this purpose. 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.
