VoltMaster ‘Intelligent Transformer’
Intelligent transformer for low voltage lighting
VoltMaster is the only true voltage stabilised power supply
for 12V and 24V AC low voltage light sources.
VoltMaster can be positioned at great distance from the lamps,
and thanks to its unique voltage sensing circuitry delivers the
optimum stabilised voltage at the actual lampholder (overvoltage
greatly reduces lamp life, and undervoltage reduces light output).
It gives brighter and sharper illumination than alternative high
frequency electronic transformers.
VoltMaster gives extraordinary lamp life. Using good quality
lamps it can extend lamp life four times more than claimed by
lamp manufacturers and this at the optimum voltage. This
voltage shows the true colour and sparkle which makes this
light source so popular. Dimming further increases lamp life.
VoltMaster has also been proven to be especially effective at
controlling and dimming the replacement LED MR16 lamps as
well as other AC LED sources.
It gives exceptionally smooth dimming using an industry
standard 0-10V signal, stabilising the brightness at all levels
down to effectively zero output.

Installation, technical specification and wiring design information is available at www.multiload.co.uk/technicalinformation.php
Pluggable Distribution Box
PDB greatly simplifies VoltMaster installation. It allows
a single feed cable to be run most of the way to the lamps
and then locally distributed to each individual light fitting.
Benefits and features
•
Fits through standard 75mm cut-out, ensuring easy
maintenance by removing the need for access hatches.
•
Reduces number of connections made by electrician.
•
Allows connection of lamps of different wattage.
•
Single feed cable from remote VoltMaster, local to lamps.
