The PSU 10 is a single-phase, computer controlled voltage source designed for use in meter test systems and in the laboratory. It is offered in three performance steps with 1000 VA, 2000 VA and 4000 VA output power available. The modules are housed in a 19 inch plug-in unit, 6 height modules, depending on output power.
The PSU 10 voltage source generates an isolated, variable alternating voltage decoupled by a transformer. The output voltage is stabilized by an internal feedback loop and overlaid digital control loop for amplitude, phase angle and distortion factor. Harmonics and ripple control can be added to the fundamental wave.
Internal circuits protect the source against overload, short circuit, mains breaks and energy recovery. The use of a voltage stabiliser at the entry point is not necessary.
Control of the source is achieved via an optical serial interface. A ring bus system and a synchronizing signal interface, both with optical terminals, allow the connection of several sources to a poly-phase system.
For safety reasons adding the STE 10 control unit to the PSU 10 is strongly recommended. The STE 10 has the following functions:
• On-off switch
• Emergency stop switch
• Protection against short circuits between U and I in the output circuits
