Description Electronic Dimmer, 15.10 Control of up to 32 slave dimmers or direct control of a 0-10 V load (e.g. electronic ballast). Selectable memory. Staircase lighting function with shut-off warning. Dimming speed is adjustable. Output contact 6 A for switching the load. Connection voltage 110-230 V AC. The Master Dimmer type 15.10 from Finder provides a warning before it switches off. Equipped with a pre-warning function, it allows, for example, staircase or corridor lighting to dim to 50% after a set time before completely turning off after another 10 seconds within 30 seconds. This pre-warning function according to DIN 18015-2 significantly reduces the risk of accidents, especially in staircases, as people are not suddenly left in the dark. Finder has combined all the functions required in modern building automation into the compact Master Dimmer 15.10, including dimming for all common light sources with and without memory functions.
