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 slot)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.

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