dimMA compact RCBO module, 12 x 3kVA, 280µs
Compact digital dimming system with single RCBO per channel
The easy way of dimming
With the new and innovative digital dimming systems dimMA and dimMA compact MA Lighting combined the well-known reliability of their touring dimmers with both the MA-Net2/MA-Net network architecture and outstanding features for permanent installations.
With the dimMA compact RCBO, every channel is protected with single RCBO (a combination of RCD and MCB), to reach a new level of safety and to ensure the operation of the remaining channels even if a single channel causes an earth leakage or over-current.
Every dimMA compact RCBO module comes in a solid 4 units housing and single RCBO per channel. This allows up to 96 channels in a cabinet, which is a Rittal rack. It has a foot print of only 0.36 m² so it can be packed tightly. dimMA compact RCBO offers the same features as the well known dimMA/dimMA compact system and provides the same easy accessibility of all load terminals and connections from the front side of the cabinet. Due to this it is easy to install. 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. All connections and outgoing lines are located inside the cabinet. Power feed and outgoing cables can either be routed from the top or fom the bottom of the cabinet.
Rugged cabinet construction
The cabinet can be fitted with 8 modules of 12 channels (a maximum of 96 x 3,000VA) or 8 modules of 6 channels (a maximum of 48 x 5,700VA). Each module is equipped with single RCBO (C13/30mA) per channel. Every cabinet is equipped with one centralised power distribution module, which contains the main circuit-breakers for each dimmer module. In addition switch modules 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 Power Supply Unit. Upon request, the cabinets can be equipped with special components such as main circuit-breaker or additional parallel output terminals.
The plug-in modules for the dimMA compact RCBO 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 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.
