1 normally open contact, not potential-free, 600VA and 1-10V control output 40mA. Standby loss only 0.5 watts. Minimum brightness and dimming speed adjustable. With children's room and snooze function. Series-mounted device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. Zero-crossing switching to protect contacts. Also for controlling LED converters with passive 1-10V interface without auxiliary voltage up to 0.6mA. Above that with auxiliary voltage. Universal control voltage 8..230V UC, local and central on/off with the same potential. Supply voltage 230V galvanically isolated. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with high performance from special relays. The set brightness level is saved when switched off (memory). In the event of a power failure, the switching position and brightness level are saved and it will be switched on when the supply voltage returns, if necessary. The minimum brightness (fully dimmed) can be set using the upper % lamp rotary switch. At the same time, it is determined whether the children's room circuit and the snooze circuit are active (+KI +SL). The dimming speed can be set using the lower dim speed rotary switch. The load is switched on and off using a bistable relay at the EVG output. Switching capacity fluorescent lamps or low-voltage halogen lamps with EVG 600VA. 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. Direction buttons can either be connected to arrow up/arrow down, or these connection terminals can be bridged and a button connected as a universal button. The direction buttons can then be arrow up to switch on and dim up, and arrow down to switch off and dim down. Double-clicking the top arrow triggers automatic dimming to full brightness at dim-speed. Double-clicking the bottom arrow triggers the snooze function. The children's room switch is operated using the button at the top arrow. As a universal button, the direction is reversed by briefly releasing the button. Children's room switch KI (universal button or direction button arrow up): When switched on by pressing the button for a long time, the light switches on at the lowest brightness after approx. 1 second and, as long as the button is continued, it slowly dims up without changing the last saved brightness level. Snooze function SL (universal button or direction button arrow down): A double pulse dims the lighting from the current dimming position to the minimum brightness and then switches it off. The max.The dimming time of 60 minutes depends on the current dimming setting and the set minimum brightness and can be shortened accordingly. The light can be switched off at any time by briefly pressing the button during the dimming process. A long press during the dimming process dims the light up and ends the snooze function.
