Surge switching relay 230V+UC. 1 normally open contact not potential-free 10A/250V AC, incandescent lamps 2000W, delay on release with switch-off warning and permanent light can be switched on with a push button. Standby loss only 0.7 watts. For built-in installation. 45mm long, 45mm wide, 18mm deep. Contact switching at zero crossing to protect the contacts and lamps, in particular this extends the service life of energy-saving lamps. The latest hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. By using a bistable relay, there is no coil power loss and no heating as a result, even when switched on. After installation, wait for the automatic short synchronization before connecting the switched consumer to the mains. Control voltage 230V, additionally with galvanically isolated universal control voltage 8..230V UC. Supply and switching voltage 230V. Very low switching noise. Time setting up to 120 minutes in the ESV function. Buttons with a glow lamp current of up to 50mA can be connected to the control input with the glow lamp symbol. If the supply voltage fails, the device is switched off in a defined manner. If the delay time is set to minimum in the ESV function, the release delay is switched off and the normal impulse switch function ES results. Can be switched to the ER switching relay function. No glow lamp current is permitted in the ER function and only control inputs A1-A2 should be used. The ER function is also suitable for feedback with the switching voltage of a dimmer switch. If the switch-off pre-warning is switched on, the lighting flickers starting around 30 seconds before the time expires and a total of 3 times at increasingly shorter intervals. If the button permanent light is switched on, it can be set to permanent light by pressing the button for longer than 1 second, which switches off automatically after 2 hours, or can be switched off by pressing the button for longer than 2 seconds. If the switch-off warning and the button permanent light are switched on, the switch-off warning only occurs after the permanent light is switched off.
