Application:
IMPORTANT: See “Recommended Load” information below.
Use one AC/DC converter with each VARILIGHT 50W, 70W and 105W low voltage transformer to power either 12V d.c. LED
Strips (or 12V d.c. LED Lamps).
More than one AC/DC converter can also be connected
in parallel
to VARILIGHT transformers with a rating of 150W or
higher as long as there is a uniform load per converter.

LED Strip Installation:
1) To power 12V d.c. LED strips use a VARILIGHT transformer with one or more AC/DC converters (see “Recommended
Load” information above.
2) The number of VARILIGHT transformers and AC/DC converters should be matched to the power of
LED strips you want to connect as shown above.
3) The maximum single length LED strip you can power from each AC/DC converter is 5 metres.
4) It is possible to power several lengths from one AC/DC converter as long as the total load is less than 50W by connecting
the LED strips in parallel (see Fig. 1 and Fig. 2 below for possible configurations)
Dimming LED Strips
Choose VARILIGHT
®
V-Pro dimmers to dim LED strip lighting. Refer to the maximum load information for low voltage
transformers provided with the dimmer to determine the maximum permitted load (measured by the total wattage of
transformers to be connected) and, in any case, do not exceed 250W per dimmer circuit.
