Product and Applications Description
The switching/dimming actuator N 526E02 is a N-
system DIN-rail mounted device for controlling up
to eight groups (channels) of fluorescent lamps via
the DC 1-10 V control terminal of dimmable elec-
tronic ballasts (e.g. ECG-Dynamic-type from Osram).
In addition there is per channel a switching contact
for direct switching on/off of the connected fluores-
cent lamps. This contact can be operated manually
via a slide switch which also indicates the actual
switching state of the channel (when switching
manually as well as when switching via the bus). A
channel is switched on when the slide is in the
lower position.
Different functions can be configured per channel
such as for switching on/off fluorescent lamps,
dimming up / down or setting a particular dimming
level.
With the ETS (Engineering Tool Software) the appli-
cation program is selected, its parameters and ad-
dresses are assigned appropriately and downloaded
into the switching/dimming actuator.
One channel of the N 526E02 switching/dimming
actuator can control several dimmable electronic
ballasts. Their number is limited by the switching
capacity and by the control power. If the on/off
function is not used via the switching contact of the
switching/dimming actuator, the number of control-
lable ECGs is only dependent on the load of the DC
1-10 V control voltage. This might allow to control a

larger number of ECGs (see Technical Specifications
below).
The power supply of the N 526E02 electronics is
provided via the bus (i.e. it requires no additional
power supply). When projecting an installation it
has to be considered that a N 526E02 represents a
double (and for short times even a triple) bus load
and takes up to 30 mA from the bus.
Application Programs
The switching/dimming actuator N 526E02 works
only together with the application program 25 A8
Switch-/ Dimm Actuator 981301. This new applica-
tion program contains several modifications and
new functions (e.g. an integrated 8-bit scene con-
trol). The application program can be loaded from
ETS2 V1.3 onwards.
