Max. temperature of housing: 75°C
Dimensions: 195mm x 50mm x 23mm
Wire length: Min: 30 cm from lighting unit to transformer

• Preheat function: protects against current surge.
• Secondary side short circuit protection: short circuit protection.
• Detect overload design: over load protection.
• Dimmable with most standard dimmers.
Electronic transformers must not be used in the same circuit as inductive loads
(fluorescent lamps, discharge lamps, ventilating fans etc.) When switching Inductive
loads, spikes of several thousand volts may result, causing damage to the transformer.
Separate load circuits must always be provided.
Under load on output may lead to lamp flickering, especially on dimmer circuits.
Conventional and electronic transformers cannot be used with the same dimmer.
The length of the secondary wire (12V side) must not exceed 2 meters.
The transformer is designed to be used exclusively with 12V halogen lamps. Soft start
protects filaments and prolongs lamp life. In case of short circuit and overload, the unit
shall automatically reset when fault is removed.
1. Please note the requirement to dispose of Waste Electrical & Electronic Equipment separately from household waste (WEEE
marked with crossed out wheelie bin symbol).
2. Please consider your role in contributing to re-use and recycling by returning this product at end of life to a collection centre
for waste electrical equipment or a Civic Amenity site, or to a retail outlet from which you are purchasing a replacement.
3. This equipment may contain substances that are hazardous to health and the environment if disposed of carelessly. It is
important that it is separated from normal household waste and recycled in the WEEE chain
4. The “crossed out wheelie bin symbol” on a product indicates this equipment must not be disposed of in normal household
waste, but should be disposed of according to local WEEE regulations

Warning:
It must be ensured at the installation that a protection against electric shock is
provided.
Cross over must be avoided with the primary and secondary lines to prevent
introduction of radio interference to mains.
Secondary cable size: 4.2A output per lampway: use 1.0mm2or larger cables to
avoid overheating.
Caution!
Do not lead the primary line
along the transformer.
Do not link the output of multiple transformers.
Avoid overheating due to being too close
to the lamp
Long 12V wires may radiate radio
interference
Warning to Electrical installers!
Do Not load the transformer over its maximum wattage as indicated.
Do Not test-Meggar Electronic Transformers.
Mains & 12V Junctions in ceiling void must be enclosed to ensure adequate
shock protection!
Installing Extra Low Voltage
Lighting in ceiling space:
Avoid excessive heat build-up by clearing insulation around both luminaire
and Electronic Transformer
No thermal insulation may be used above the fittings or transformer.
