PSP Family Modules and Plug-in Units
Individual use for processes where controlled DC power supplies are needed. Electrolytic Special Applications and Plating Processes, Pulse Applications.
Modular, high-frequent ½-19"- or 19" switch-mode Technology including a standardized analog interface. EMC-compliant and rounded-up with a high-tech finish the PSP Family modules and plug-in units are intended for the installation in an industrial control cabinet. One of the outstanding features of this compact power supply is the constant low ripple which provides excellent DC quality.
Beyond galvanically isolated setpoint and actual values (0-10 VDC), optional
4-20 mA or Profibus DP the devices are short-circuit proof and resistant against over temperatures.
The air-cooled PSP Family rectifiers are available as PSP Boxes also.
The switch-mode rectifier is featured with the following five functions:
High-frequent disturbances are reduced in the mains filter (1). On the other hand the mains filter is used to dampen the interference voltages. The mains rectifier converts the voltage into DC voltage (2). The power electronics (3) then convert the DC voltage pulse width modulated into a staircase-shaped alternating voltage. The internal transformer (4) stands for a galvanic potential separation and voltage adjustment on the secondary side. On the output side rectification is achieved by fast power diodes (5). On the output side a constantly smoothed and fully controllable DC voltage is generated.
Especially adapted for Multi Circuit Rectifier Cabinets the psp family Modules and Plug-in Units offer a high packaging density. Furthermore they are featured with a central feed-in as well as a central interface for communication and cooling.
Due to the customer-specific design the Multi Circuit Rectifier Cabintes are particularly efficient.
