Type Description

UP 255/11

AP 255/12

UP 255/11 and AP 255/12 brightness controllers

• For measuring the brightness on an illuminated work area

through measurement of the reflected light

• Measuring range 0 ... 2000 lux (with a reflectance of the

illuminated area of approx. 30 %)

• Including two rigid optical fiber rods:

- Parallel light-sensitive surface for mounting surface

- Inclined (45°) light-sensitive surface for mounting surface

• Integrated infrared receiver for calibration of the brightness

measurement over an infrared remote control

• Transmission of the brightness measured value, either in the

event of change and/or cyclically

• Optional two-step dimmer control for lamps that can only be

switched, or constant light level control for lamps that can be

switched and dimmed

• Setpoint can be adjusted either over a parameter or a

communication object

• Starting value of the lighting can be selected when the constant

light level control starts up

• Optionally with dimming of up to 4 further lamp groups

• To the dimming value of the constant light level control or to a

dimming value that differs from the dimming value of the

constant light level control by an offset value, which can be

set per group

• Automatic deactivation of the constant light level control by

manual BRIGHTER/DARKER dimming or dimming to a preset

dimming value

• Configurable behavior in the event of a bus power recovery

UP 255/11

• For mounting in a hollow-wall or flush-mounting box with

∅

58 mm and min. 40 mm mounting depth

• Cover made of white plastic (polystyrene)

• Dimensions (H x W x D): 30 x 52 x 33 mm

AP 255/12

• For ceiling or wall mounting

• Includes surface-mounting enclosure made of white plastic

(polypropylene) with

∅

70 mm and 24 mm in height

• Dimensions (H x W x D): 30 x 72 x 33 mm
