TDK Lambda Z+ Programmable Power Supplies
|TDK Lambda highlights the unique arbitrary waveform generation capabilities of the TDK-Lambda Z+ Series of high-density, 2U format benchtop and rack mounted 200W and 400W power supplies. The ability to create and store up to 4 application specific test waveforms removes the need for an external controller in basic simulation tasks.
Up to 12 values can be programmed via the front panel or supplied software CD and 4 waveforms can be stored in the Z+ unit?s memory, while longer, more complex strings can be controlled using the LabView? GUI. These waveforms can be either repetitive or single-shot and injected into the system under test and analysed confirming the proper operation of the powered system or pinpointing a fault.
A typical test environment would be to simulate the characteristics of another power source, for example to simulate car battery voltage transients occurring under all conditions including starting according to DIN 40839 for testing automotive electronics. The DIN 40839 standard ensures electromagnetic compatibility in road vehicles and defines several types of tests, including the injection of supply line transients (test pulses) in 12 and 24V onboard systems.
Another typical application is to simulate the output profile of a solar cell array under all conditions in order to test connected equipment.
Z+ Power Supplies also have a fast command processing time, output sequencing and, uniquely, two programmable output pins that can be used to control the isolation relays for example without the need of a separate PLC. This simple control circuit enables the test engineer to connect and disconnect the load remotely for certain fault conditions, as well as for applications requiring reverse polarity.
