• Dimming range 1 %…100 % (the lower limit depends on the lamp

and manufacturer). The progression of the characteristic is stan-

dardized and adapted to the sensitivity of the eye (logarithmic

characteristic). Because of the standardization, a similar sense of

brightness is achieved when using control units from different man-

ufacturers

• Programmable dimming times – special settings such as light

change speeds (e.g. from 1 % to 100 % dimmer setting) are pos-

sible

• Disconnection of the data line – the specified light values are ad-

opted automatically

• Storage of light scenes (different group-dependent dimming states)

– up to 16 scenes can be stored

• Connection via converter to building management systems – the

interface is primarily conceived for room applications; it can be in-

tegrated into building management systems via gateways

• Simple system reconfiguration – once the system is set up and

configured, changes of the system function, the light scene and

light functions are only a matter of configuration and do not require

any changes to the hardware. Example: Regrouping of luminaires

in a large office building

• Simple integration of new components – if an existing illumination

system is to be extended, new components can be added any-

where within the system. Attention must be paid here to adequate

dimensioning of the system supply

• Polarity freedom of the interface

2.9 Characteristics of the 1…10 V interface

Note:

This chapter is based on OSRAM ECGs types QTi DIM and HF DIM,

abbreviated to OSRAM DIM ECGs in the following

• Control is carried out via a fail-safe DC signal of 10 V (maximum

brightness; control line open) to 1 V (minimum brightness; control

line shorted)

• The control power is generated by the ECG (max. current: 0.6 mA

per ECG)

• The voltage on the control line is voltage-insulated from the mains

line (basic insulation), but there is no safety extra-low voltage

(SELV)

• ECGs in different phases can be dimmed by the same controller
