PowerRack, air-cooled

Application:

Plating Processes,Electrolytic Special Applications, Water Treatment, Automated Processes, PulseApplications

Product Description:

The switch-modePowerRack is a complete modular rectifier designed as a ready to go system forgenerating a high DC quality, available in air or water cooling.
PowerRackrectifiers are best characterized by their full control, their range capabilityand incorporated redundancy as well as robustness. The capsulated 19"power modules of the PowerRack are by themselves complete rectifier circuitsfeaturing their own EMC filters, accurate control circuit and cooling circuit.Power Management of the PowerRack is taken over by the digital MasterController, operated by a micro-processor. Both DC and pulseed DC operationmodes are supported. By means of the availalbe interface card, PowerRacksystems can be easily integrated in the plant control system. PowerRack is therobust and lasting power supply solution for the plating industry.

PowerRack rectifiersare also available in water-cooling.

Block Diagram:

The switch-moderectifier is featured with the following five functions: 
High-frequentdisturbances are reduced in the mains filter (1). On the other hand the mainsfilter is used to dampen the interference voltages. The mains rectifierconverts the voltage into DC voltage (2). The power electronics (3) thenconvert the DC voltage pulse width modulated into a staircase-shaped alternatingvoltage. The internal transformer (4) stands for a galvanic potentialseparation and voltage adjustment on the secondary side. On the output siderectification is achieved by fast power diodes (5). On the output side aconstantly smoothed and fully controllable DC voltage is generated.

Customer Benefits:

Especially tailoredto the needs of the modern plating industry, PowerRack combines our long-termexperience in manufacturing rectifiers for the plating industry with the latestdevelopments available in power electronics and digital control technology. Itis the ideal solution for those looking for an affordable solution for today'srequirements, while also enabling future capacity upgrades and keepingoperating costs low.
