ELTAKO Impulse Switch UC. 1 NO contact potential-free 10A/250V AC – 61100501

1 NO contact, potential-free 10A/250V AC, 230V LED lamps up to 200W, incandescent lamps 2000W. No standby loss. For flush mounting. 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 12..230V UC at control input +A1/-A2 or 230V with up to 5mA glow lamp current at control input (L)/-A2(N). The simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No permanent power supply required, therefore no standby loss. Due to the use of a bistable relay, there is no coil power loss and no heating in the switched-on state. The relay contact can be open or closed during commissioning and synchronizes itself at the first operation. If this impulse switch is in a circuit that is monitored by a field disconnector FR12-230V, no additional basic load is required, but the monitoring voltage of the FR12-230V must be set to max. The electronics have no own power supply and therefore no power consumption in either contact position. Only during the short control pulse of only 0.2 seconds does the control current flow, which activates the microcontroller. It reads the last switching state from its non-volatile memory, switches the bistable relay accordingly in the opposite direction and writes the new switching state back to the memory.
