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

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
