This adjustable and programmable laboratory power supply series PSI9000 in the 19 "- 3U slot format has an extremely powerful FPGA (Field Programmable Gate Array) control unit with a resolution of 16 bit. The output stage is flexible (auto-ranging output), which means operation with high output voltage or optionally high output current within the nominal power.
The multifunctional control unit of the PSI9000 power supply is equipped with an intuitive touch panel and has a function generator, U, IP display resolution up to 5 digits, memory and various other helpful functions. For remote control, the devices have a galvanically isolated analog (0-10V) and USB interface as well as a plug-n-play slot, in which further optionally available interfaces can be retrofitted (CANopen, Profibus, Profinet, Modbus, RS232 uw).
The built-in function generator is able to generate different waveforms and apply them to one of the setpoints voltage (U) or current (I). The following functions can be called up, configured and controlled manually: sine, square, trapezoid, DIN 40839 emulated car engine start curve, arbitrary, ramp and PV curves. The function generator is connected upstream of the power supply and thus controls the amplitude and the period of the output voltage up to a certain frequency (depending on the rise and fall time) in order to supply test objects with real voltages and current profiles.
The devices provide extremely stable output values with very little ripple and are very dynamic in their control. They are ideal for highly demanding laboratory and industrial applications, especially for automatic test benches in 19 "rack technology with outputs of several 100kW.
