Impulse changeover switch Flush mount Eltako ES61-UC 1 maker 230 V 4 A 2000 W 1 pc(s)

Impulse switch UC. 1 normally open contact potential-free 10A/250V AC, incandescent lamps 2000W. No standby loss. For panel mounting. 45mm long, 45mm wide, 18mm deep. The latest hybrid technology combines the advantages of wear-free electronic control with the high power of special relays. Either universal control voltage 8..230V UC at control input +A1/-A2 or 230V with up to 5mA glow lamp current at the control input with glow lamp symbol (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 thereby even when the relay is switched on. The relay contact can be open or closed during commissioning and synchronizes itself during the first operation. If this surge current switch is in a circuit that is monitored with a field isolator FR12-230V, it does not require an additional base load, 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 both contact settings. Only during the short control pulse of only 0.2 seconds the control current, which activates the microcontroller, allows it to read 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.
