Digital dimmer cabinet

Eurodim 3 is an intelligent dimming system with individual plug-in modules.

ADB's Eurodim 3 is a high-density 270kW cabinet with all digital plug-in dimmer modules for professional theatre and television installations.
The Eurodim 3 dimming system provides accurate, stable and reliable performance, combined with comprehensive remote programming and diagnostic functions. Efficiency is better than 98% at rated load.

Plug-in Digital Dimmer Modules

Eurodim 3 utilises individual digital dimmer modules with proven design and reliability. The modules are inserted into 'Crates' within the Eurodim 3 cabinet, each of which can house 9 dimmer modules.
Hot Patching of modules is allowed, thanks to a power connector with sequenced mating of the contacts.

Dimmer modules are available in a number of configurations:
Eurodim Dimmer Modules

Dual 3kW;
Single 3kW Fluorescent;
Single 5kW;
Duaul 5kW;
Single 10kW;
Relay module;
Bypass module;
Feed-through module.

The dimmer modules contain hard-fired thyristors for control of 220/240V tungsten halogen lamps, resistive and inductive loads, transformer-fed low voltage lamps, and fluorescent lighting with suitable ballasts. Cold tungsten lamps are allowed without damage to the thyristors.
Relay, bypass and feed-through modules are available for non-dimmable loads.

All dimmer modules are rated for continuous duty at 35°C ambient temperature. The generously sized heatsink provides efficient cooling, and its large thermal inertia has a stabalising effect on the temperature.
Three indicators provide a quick overview of the dimmer status: Fuse OK/MCB On, Output voltage, Output Current.

Filtering

Dimmer modules are designed to TV broadcast quality filtering (BBC, TDF) with large toroidal filter chokes, 450µs rise-time (10% to 90%). Professional quality filtering (200 µs) is available as an alternative.

Cabinet Sizes & Protection

Two cabinet sizes are available: DD3 180/270 divided into a maximum of 5 crates - for up to 90x 3 or 5 kW dimmers, and DD3 225/270 divided into a maximum of 6 crates - for up to 108x 3 or 5 kW dimmers.
Eurodim 3 is available with optional individual crate protection (45 kW) for maximum safety and operating comfort.

Each Eurodim 3 cabinet has assisted ventilation by means of 6 low-noise fans, providing regulated airflow and automatic stop. The performance of each fan is monitored individually.

Standard Configurations

Without crate protection:

45 or 54 dual 3 kW modules;
45 or 54 single 5 kW modules;
45 or 54 dual 5 kW modules.

With crate protection:

36 or 45 dual 3 kW modules;
36 or 45 single 5 kW modules;
36 or 45 dual 5 kW modules depending on cabinet size.

Combinations of 3 kW, 5 kW and 10 kW dimmers are possible.

Control Inputs

Eurodim 3 accepts two DMX 512/1990 digital control inputs, each with it's own individual soft-patch, combined with ADB's ADN Dimmer Netwok on pins 4 and 5 of the DMX cabling. An optional multi-protocol input (DMX 512, ADB S20, AVAB, D54 or AMX 192) is available. Both the DMX and ADN data inputs are opto-isolated.

Dimmer Functions

Control of all Eurodim 3 functions is made through the on-board 5-key keypad and 12-character LED display, using an identical menu system found on the Eurorack 60, Memorack & Memopack dimmers. All dimmer functions can be controlled remotely by using ADB's ADN Dimmer Network System.
As an option, double control electronics provide instant back-up in the event of a failure.

10 user-selectable dimmer laws: linear r.m.s. voltage, linear r.m.s. to 120V, TV laws (BBC, TV1, TV2), non-dim with hysteresis, fluorescent, linear r.m.s. voltage with preheating, square law, user-programmable custom law.
Voltage reduction factor for extended lamp life or variable load cable length compensation.
4000-step fade resolution, for noticeably smoother fades.
Global or individual programming of dimmer law, patching, voltage reduction factor and smoothing.
Restore House Patch function recalls a preferred DMX patch.
Creation and storage of 20 lighting cues (19 + Priority) each with fade and wait times, for back-up cues, working lights, or standalone operation.
After loss of DMX data: maintain last levels, or wait and fade to one of the internal cues, or wait and fade to black.
All programmed data saved for unlimited time.

Electrical Protection

Eurodim 3 can provide an exceptional level of electrical protection and reporting, allowing the cabinet to be tailored to specific system requirements.

Each dimmer is protected by a HRC fuse (100 kA), with 'fuse OK' indicator; optional dimmer protection by MCB;
Dimmer protection is available in three versions: single-pole, single-pole + N disconnect, true double-pole;
Main isolating switch with or without HRC fuses (option);
Optional crate protection, located on the front panel for direct access: 3P or 4P; HRC fuses (100 kA), MCB or MCB+RCD;
RCD protection available per dimmer module (30mA 6kA);
RCD protection per group of modules (6x 3kW or 3x 5kW) available;
Residual current monitoring and alarm module available (does not switch off any dimmer);
A three-phase power supply for control electronics and fans guarantees continuity of control and full ventilation in the event of the loss of one supply phase.

System check, dimmer and load check

Eurodim 3 reports on the status of a large number of components in real-time; all events and parameters are available on the ADN network. Important problems generate a flashing error message on the Eurodim's red alphanumerical LED display.

Up to 300 indicators and text messages for seeing at a glance the status of individual dimmers, DMX signals and CPU's, and also fan failures, over-temperature, missing supply phase...
All error messages also available on the ADN network;
Local test of a dimmer: steady, flash or chaser;
Dimmer fuse/MCB indicator, output voltage and load current indicators;
Load Scan test detects load changes, short circuits, ...
Automatic self-test of control electronics.

Extended diagnostics functions allows the load of each dimmer channel to be tested, allowing additional information about the status of each dimmer to be obtained:

Value of the load (kW);
Load deviation from reference load;
No load, overload;
Short-circuit;
Thyristor failure.

The routine is applied to one dimmer or to the whole cabinet. When the test detects a dimmer with a short circuit (e.g. in the luminaire or cable), then it will report this Short condition but it won't trip the dimmer protection.
