This dimmer can switch and dim both dimmable LED luminaires, ohmic (e.g. incandescent lamps, HV-halogen)
and inductive (e.g. LV-halogen with transformer or fans) loads with corresponding power. Low-voltage halogen
lamps may only be operated in conjunction with a wound transformer.
For the living room touch dimmer function, it is sufficient to supply the dual dimmer 1 with the 1-wire bus voltage
(12V). This enables a "Smart Home Ready" installation in your building or apartment. This also ensures extremely
high reliability, as the lighting functions when the Smart Home control is not yet programmed or has failed.
3 Auto-E-Connect® Support
The ESERA Auto-E-Connect® 1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
The Auto-E-Connect function automatically recognizes ESERA chips, sensors and actuators, starts suitable
libraries and outputs fully formatted data.
The Auto-E-Connect functionality will be available from mid 2020 via 1-Wire Controllers, 1-Wire Gateways and
1-Wire ECO from ESERA available.
Further information on ESERA Auto-E-Connect can be found on the ESERA website, ESERA Config-Tool 3, or in
the download area for this article in the ESERA Webshop.

Dimmer channels 2, Phase section Technology
Output: max. 460W / 460VA
When installed in distribution cabinets with low heat dissipation, e.g. installed in wooden
or (RI) plaster walls, the connected load must be reduced by 25%, also when the
ambient temperature rises above 25°C..
Nominal voltage: 230VAC +/-5% 50Hz
Consumers: - Dimmable LED luminaires
- ohmic loads, e.g. incandescent lamps, HV-halogens
- inductive loads, e.g. LV halogen only with wound transformer
or fans up to max. 300W / 300VA
Unsuitable - Fluorescent lamps and energy saving lamps
consumers - Low-voltage halogen lamps with electronic transformers
- PL, SL, DULUX or Biax light sources

Note on the detection of suitable and unsuitable transformers
For wound transformers, a commercially available resistance meter (multimeter) can be used to measure the
Transformer resistance (power 20-250W) with less than 50 Ohm between L and N can be measured.
With electronic transformers of comparable power, you can usually achieve resistance values of greater than
Measure 100,000 Ohm between L and N.
These electronic transformers are not suitable for the dual dimmer 1 (phase angle control).
An already wired electronic transformer must always be disconnected from the mains on the 230 V and
low-voltage side. The circuit must be disconnected (see safety instructions).
Make the connection according to one of the following circuit diagrams. The cables to be connected
should be stripped approx. 12 mm.
