Dimmer technique

1. Slot dimmer
2. Mobile dimmerpacks / hat-rail-dimmer


The flightcase with 24 digital slide-in dimmers has been constructed for mobile application. Every dimmer module is self-sufficient and can be adressed individually.
Phase section dimmer in modular construction for 19", system 3 HE.
Dimemr per 19": 8 pieces (50 A: 4 pieces)
Available installation sizes 13 A = 2,5 kVA, 16 A = 3 kVA, 25 A = 5 kVA and 50 A = 10 kVA (double slot width)

This Lightcontrolsystem is featured
 -  with LED-displays at the frontshield: DMX-signal, phase section (brightness) and
NON-DIM active display
 -  with a filter for round control signal, i. e. there are no influences on brightness
through power system annoyance
 -  with over-dimensioned thyristor for absolute short-circuit stability
 -  with high redundance through divided intelligence (independent processore for each
Supports all popular spot light types (excapt capacitiv loads)

The assambly groups (power supply and DMX-interface, power outlet and safeguard) are chosen individual for every customer requirement. The grade of interferrence surpressing will be adapted on the requirements.

AND 1,3 Verteilerschrankdimmer
AND 1,3 distribution box dimmer

The digital hat-rail dimmer AND 1,3 µC works with the phase section principle. At every half-wave of the sinusoidal input voltage depending on the dimmer setup an accordant piece gets cutted off. Because of over-dimensioned semiconductor compenents the dimmer is in accordance with a pre-fusing short-circuit proof. A filtercircuit, which effectivly holds away any disturbances from the zero-recognition, is included, thereby jittering of the light is prevented. There are multiple application areas.

The dimmer is suited to used:
 ·  NV-halogen lamps with conventional transformers
 ·  HV-halogen lamps
 ·  filament lamps (AGL)

This light control unit is featured
 ·  with thyristors instead of a triac, in order to minimize the direct current proportion and maximize the short-circuit power
 ·  with a micro-processor controlled ignition, in order to reach a most symetric triggering
 ·  the control electronic is power system seperated with 4 KV
 ·  with arbitrary light curve

 ·  Low power usage (1 - 10 V)
 ·  Tactilefunction with single- or double button
 ·  Manual potentiometer (P10G/K)
 ·  Triggering over tactile pad
