expense. Smaller transformers and backup generators can be purchased, offering
great savings.
Environmentally friendly: Providing a pure sinewave, iSine technology avoids the
peak currents which stress filaments and also eliminates harmonic currents which
can affect other equipment and cause transformers to overheat. Cables and
generators also benefit - with a pure sinewave supply, the infrastructure does not
have to be overrated (usually 40% excess for normal dimming systems).
Versatile: The sine wave control is the most versatile dimming technology for
resistive and inductive loads. Almost any load which can be dimmed is dimmed
effortlessly with sinewave.
Non-Dim Switches
Relay switch modules are available for regular loads of either 16A or 32A with
options of MCB, RCD and RCBO. HMI switch modules are also available in 4kW and
10kW capacities with cosine measurement to monitor correct lamp ignition.
Distributed processing
Each plug-in dimmer module has integral processing to maintain basic operation
even if a processors fails in the Matrix Rack Processor unit.
New to Matrix Mk.II
Higher density
The original Matrix offered a maximum of 162 x 2.5kW, 108 x 5kW or 27 x 10kW (or
mixtures of all three dimmer ratings). The new Matrix Mk.II is designed around a 4U
high module (44mm taller than previous modules) with space for up to 6 dimming
channels per module.
Increased economy
By increasing the dimmer count in each module to a maximum of 6, the per dimmer
cost can reduce for high-density installations.
Greater choice of channel ratings
The enlarged module size now allows for a rating upgrade from 2.5kW per channel to
3kW for SCR and sine wave. Sine wave dimmers are also available in 1250W,
2.3kW, 5kW and 12kW ratings.
Improved efficiency
Even though the previous Matrix sine wave dimmers were very efficient for their type
(typically 97%), the new design includes a frequency boost to improve efficiency to
98%, better than many traditional SCR dimmers.
