dimMA compact module, 12 x 3kVA, 280µs, 4HE

Compact dimmer for permant installations

The easy way of dimming

Art.No.: 140161-1

Discontinued

With the new and innovative digital dimming system dimMA compact, the well-known reliability of the MA touring dimmers in combination with the outstanding fea­tures of the dimMA system is now available for permanent in­stal­lations. All features of the dimMA system are the same as for the dimMA compact. It is just called compact due to the fact that it is only 4 units high and offers a 12 channel fitting.

This allows 108 channels in a dimMA cabinet, which is a Rittal rack. It has a foot print of only 0.36m² so it can be packed tightly. All connections and outgoing lines are located inside the cabinet. The modular connection system on the back side of the modules makes it easy to change modules and makes any additional load terminals or patch fields unnecessary. Power feed and outgoing cables can either be routed from the top or from the bottom of the cabinet.

Rugged cabinet construction
The cabinet can be fitted with 9 modules of 12 channels (a maximum of 108 x 3,000VA) or 9 modules of 6 channels (a maximum of 54 x 5,700VA). Each cabinet can be populated with modules of different types.
In addition switch modules (with relay) are available that are compatible with phase-cut modules. Thus the digital dimming system for installations is ready for the future and based on proven and rugged technology.
For power input (TN-S net), there is an integrated three-phase bus-bar system with a load capacity of 400A per phase.
Upon request, the cabinets can be equipped with special components such as main circuit-breakers, additional parallel output terminals and RCD per channel.

Dimmer modules
The plug-in modules for the dimMA digital dimming system are available with load ratings of 12 x 3,000VA or 6 x 5,700VA with a rise time of 280µs. Each dimmer circuit has high quality thyristors and filter suppression.
This allows us to offer the optimal solution for every kind of application while also taking economic aspects into consideration. Each dimmer module features a separate single-PCB computer with power supply and communicates with the MA NDP (Network Dimmer Processor) of the cabinet via a CAN-bus interface. Dimmer modules of the same rating may be freely exchanged; any assigned settings such as dimmer number, dimming curve, non-dimming operation, and special and/or panic functions remain linked to the plug-in slot location and apply to any new module inserted.
Each module is cooled with two temperature-controlled fans activated only if the module is actually in use. This reduces drastically the amount of noise produced by the dimming system because only those components are cooled that need it. Via the MA NDP, each dimmer circuit provides the lighting control system with detailed information about current and voltage, the status of the load connected, and about any faults occurring.
