Can I operate the transformer with a standard dimmer switch?

No, not with a leading edge or trailing edge phase dimmer. You can use our 1-10V dimmer switch which adjusts only the level of brightness. The transformer must be switched on and off via the supply cable with Euro plug. Any other 1-10V dimmer switch may be used to perform both functions, but in this case the control cables and the supply cable of the transformer must be connected to the dimmer switch by an electrician.

Can I operate the transformer without a dimmer switch?

Yes, without a dimmer switch the transformer will run on max. brightness.

How can I connect multiple transformers to a single dimmer switch?

Additional transformers can be connected using the Mini Y-distributor (216 020 300 06 with one plug and two couplings) or the Mini 6-way distributor (215 080 604 02).

The luminaires switch on by themselves.

The sensor cable should not be coiled up, should not be laid parallel to other cables or electrical appliances, and should be shortened, if possible.

When there is a power failure, does the switch automatically return to its last setting before the interruption?

No, the EBS does not remember its last setting if for instance the main switch is also operated (central switch on the display). In this case it is always off.

How much power does it consume in standby mode?

approx. 0.7W

Can I connect multiple sensor cables?

Yes, if you simply connect the sensor cables using a luster terminal. However, this can cause functional problems (see above).

Why does the XL DC 2 dim control have two control cables?

Two strip lights with a maximum of 10 luminaires can be connected to different dimmer switches. If only one dimmer switch is required, both control cables can be connected parallel to the dimmer switch. You can then take the Mini Y-distributor (21602030006) for the dimmer switch with Mini-AMP beech.

How many luminaires can be operated on one dimmer switch?

Two light strips of a maximum of 10 luminaires can be connected to one XL DC 2 dim control. Then you need a dim-amplifier XL DV 1 with additional Euro plug supply cable. Here too, two strip lights of max. 10 luminaires can be connected. By using a maximum of 10 amplifiers per control it is possible to connect a total of 220 luminaires.

Can I operate the transformer with a standard dimmer switch?

No, not with a leading edge or trailing edge phase dimmer. You can use our 1-10V dimmer switch which adjusts only the level of brightness. The transformer must be switched on and off via the supply cable with Euro plug. Any other 1-10V dimmer switch may be used to perform both functions, but in this case the control cables and the supply cable of the transformer must be connected to the dimmer switch by an electrician.

Can I operate the transformer without a dimmer switch?

Yes, without a dimmer switch the transformer will run on max. brightness.

Does the control automatically return to its last setting when a power failure occurs?

Yes, the last dimmer setting is restored, if there is an additional primary connection (e.g.central switch on the display).

Can I connect more than the nominal load to the transformers?

Yes, however this depends on the ambient temperature (Ta): This is 10% (16.5W / 33 W / 66W) at Ta 25°C. This is still 5% (15.8W / 31.5W /63W) at maximum Ta (15W = 40°C / 30W = 45°C / 60W = 40°C).
