Eltako 61100501 ES61-UC surge switch 8–230 V UC, 1 S potential-free 10 A/250 V content_copy

1 normally open contact potential-free 10A/250V AC, 230V LED lamps up to 200W, incandescent lamps 2000W. No standby loss. For built-in installation. 45mm long, 45mm wide, 18mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. Either universal control voltage 8..230V UC at the control input +A1/-A2 or 230V with up to 5mA glow lamp current at the control input (L)/-A2(N). The simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No constant power supply required, therefore no standby loss. 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. If this impulse switch is in a circuit that is monitored with a FR12-230V field isolator, no additional base load is required, but the monitoring voltage of the FR12-230V must be set to max. The electronics do not have their own power supply and therefore do not consume any power in either contact position. The control current, which activates the microcontroller, only flows during the short control pulse of just 0.2 seconds. It reads the last switching state from its non-volatile memory, switches the bistable relay in the opposite direction accordingly and writes the new switching state back into the memory.
