Eurodim Twin Tech Range: Hybrid installation digital dimmer cabinets
 |
|
Eurodim Twin Tech hybrid dimmer cabinet 129x 3kW / 96x 5kW modules Relay, Bypass and Feed-through modules available for non-dim loads (on request) Configurable to total of 600A |
Eurodim Twin Tech provides the best of both dimming worlds by allowing Sine Wave dimmer modules to be freely mixed with cost-efficient Thyristor dimmer modules in a single cabinet.
Mixable in any proportion up to 128 x 3 kW or 96 x 5 kW channels, divided into 32 plug-in modules, each module has a 63A supply protection for optimum safety. ADB’s R&D team made this possible through the development of a unique new Assisted Ventilation system that provides high efficiency cooling and ensures continuous and reliable operation up to the nominal power of 600A per cabinet.
Eurodim Twin Tech also incorporates new remote operation facilities which provide both multi-user remote dimmer channel assignment via wi-fi PDA’s, and remote dimmer diagnostics over an internet connection – e.g. from the ADB customer service centres.
Twin Tech rhymes with High Tech, as a look inside the cabinet will prove. So Eurodim Twin Tech, with its combination of high performance, innovative design and cost effectiveness, is expected to become one of ADB’s best selling products.
Heralding an exciting year of developments, ADB Lighting Technologies previews its new flagship in dimming technology, Eurodim Twin Tech, at Pro Light+Sound 2008 (Hall 9.0, Stand D49).
Eurodim Twin Tech brings the best of both worlds: Transistor Technology for state-of-the-art sine-wave dimming, freely mixed with cost-efficient Thyristor Technology and its proven track record. Eurodim Twin Tech comes with the full remote control features of 21st century systems.
Eurodim Twin Tech is a high-density dimmer rack with all digital, plug-in dimmer modules for professional theatre and television installations. It allows a free mix of sine-wave and thyristor technologies, and dimmer ratings. The ultimate for accurate, stable and reliable performance, combined with comprehensive remote programming and diagnostics functions.
Dimmer modules
- 4 x 3 kW thyristors; up to 128 x 3 kW per rack
- 4 x 2.5 kW sine-wave; up to 128 x 2.5 kW per rack
- 3 x 5 kW thyristors; up to 96 x 5 kW per rack
- 3 x 5 kW sine-wave; up to 96 x 5 kW per rack
- 10 kW on request
- Automatic detection of type of dimmer module
- Full diagnostics is standard in sine-wave modules and optional in thyristor modules
Free mixing of sine-wave and thyristor technology
Eurodim Twin Tech racks are compatible with all modules types and ratings. This hybrid technology offers great flexibility: in a mixed installation with thyristor and sine-wave modules, dimmers can freely be moved to suit the specific requirements of each production. Sine-wave modules can thus be allocated to acoustically critical locations or luminaires. No reprogramming is necessary.
Benefits
ADB Eurodim Twin Tech dimmer racks offer a number of benefits, both to the installer and the user. In addition to the use of sinewave modules, a unique Human Interface is provided. in addition, multi-user wireless remote dimmer control is possible, thanks to PDA-based wireless Remote Dimmer Controllers. These give direct access to the dimmers, independently of the lighting console. Technicians can recall cues, groups of dimmers, or individual dimmers, for focusing or test.
A summary of key features is provided in the following sections:

Remote Cue Control functions such as playing and fading up/down of the cues, starting a Cue Chaser, storing a cue, … can be triggered via the internal clock (date and time) and via standard DMX. Control systems integration is now possible without the need for specialist protocols
System check, dimmer and load check

Benefits of ADB sine-wave technology
ADB sine wave dimmer technology provides a number of key benefits over conventional dimming technologies:
- Noise free: ADB sine-wave dimmers effectively eliminate all filament noise, which makes them the preferred choice for lighting applications where lamp noise is critical.
- Loads: they have successfully been tested with a very wide range of resistive, inductive and capacitive, dimmable and nondimmable loads. These include discharge lamp ballasts (HMI), switched power supplies and 12 V converters, moving lights, electronic equipment, LEDs... No minimum load.
- Power factor: the power factor equals the PF of the load, thereby eliminating the reactive power (kVAr) typical of phasecontrolled dimmers.
- Harmonics: less than 1% harmonic distortion, no pollution sent back to the mains.
- Self-protecting: ADB sine-wave dimmers are self-protecting against short-circuit, overload and over-temperature, without MCB tripping.
- Dynamic response: similar to thyristor modules, to allow free mixing
Dimmer Manager
The Dimmer Manager PC software combines four products in one: a Cue Control system, a Status Reporting system, a Remote Programming tool, and a Commissioning & Service tool.
Dimmer Manager provides a system-wide overview of status of CPU and back-up CPU, error and alarm messages (loss of DMX, fan failure, temperature, missing phase...), and Diagnostics information about individual dimmers.
Dimmer Manager functions include downloading & uploading of dimmer parameters, on-line & off-line editing, graphical editing and library of custom dimmer laws, and creating back-ups of system configurations e.g. per show or per stage.
