Flex 120 strips are compatible with the two types of dimmer circuits shown below. However,
they are NOT suitable for use with TRIAC-based dimmers, also known as Forward phase-
control or Leading-edge dimmers.
ELV dimming
- (Electronic Low Voltage) - These dimmers use
a transistor type device to cut off the mains output before
the zero point of each half-wave cycle, thus they affect the
trailing edge of the mains sinewave. These dimmers avoid the
voltage spikes associated with TRIAC-switched leading edge
dimmers and are best suited to dimming capacitive loads
such as the electronic transformers used with low voltage
lighting. This style of dimming is also called
Reverse phase-
control
or
Trailing-edge dimming
.
Sinewave dimming
- These dimmers use an IGBT (Insulated
Gate Bipolar Transistor)
to switch the mains output at high
frequencies such that they can recreate a dimmed mains
sinewave with a varying overall amplitude. These dimmers
produce the smoothest output of all types.
DMX OR 0-10V CONTROL
Additionally, Flex 120 strips can be controlled by either DMX or 0-10V (source or sink) inputs by
using the optional Acclaim Lighting UDM (Universal Dimming Module):
DIMMING CONTROL
Each Flex 120 strip can accept dimmed mains power at 120VAC (RMS) originating from
certain types of dimmers, such as domestic (ELV) wall dimmers (connect according to
dimmer specifications):
The UDM runs from a standard mains input (120VAC) and uses a DMX or 0-10V (source or sink)
input to create a dimmed mains output from which the Flex 120 strip(s) can operate.
The UDM is able to provide fully dimmed output power from 0-100%.
