3.) For interested professional users, we can help in implementing access to the Chromoflex from
own „embedded controls". Our development team has considerable experience in all kind of
embedded developments.
Random Effects
Each Chromoflex module can generate individual random effects. Because the random coincidence is
based on a mathematical calculation, only modules with different serial numbers appear truly
different. Depending on production output this might require that the user once initialises each module
with an individual serial number (or else all modules run the same „random sequence"). Generating
an individual serial number is described in the manual for the PC-software „Chromoflex Editor".
Technical Data
Technical Data
Operating Voltage: 7 - 24 Volt (+ 5%), stabilised.
Important: The power supply used must be able to bear pulsed loads. Unstabilised or too weak power
supplies can cause unwanted flickering effects, especially during colour changes!
Module current (without LED lamps): ca. 20 mA
Operating temperature: 0°C - max. +50°C (recommended: <= 30°C) (Use only in dry places with
sufficient air ventilation)
Modulation system: The Chromoflex modules are based on a digital System, called „Vector-Fractal-
Modulation" or „VFM". This modulation system was optimised for minimising load on power supplies
and has considerable advantages compared to traditional systems. The modulation frequency is in
the range from 120 Hz up to (max.) 240 Hz. Patent pending.
Maximum cable inductance can be calculated as L_max = 40µH (maximum current). Note: Standard
control cable normally has an inductance of around 0.4-0.8 µH/m.
Model „I350"
Pulsed constant current abt. 350 mA (+ 5%, -20%) per channel (3 channels).
Model „Stripe"
Pulsed constant voltage, maximum current 2.5 Ampere per channel (3 channels) at 12 Volts, and 1.25
Ampere per channel at 24 Volts.
