PSU Board
Programmable power supply

Potential-free output voltage ± 25 V
Current limit 0.01 to 2.5 A
Integrated measurement of voltage and current
AC mode 10 to 100 Hz
Suitable for use as an electronic load

Description

The PSU board features a four-quadrant amplifier and can generate voltages in the range of ± 25 V. The integrated A/D converters can be used to measure the output current and voltage. As the output is potential-free, two boards can be connected in series without any issues in order to double the output voltage to ± 50 V. Sense inputs are provided to compensate for the voltage drop in the connecting cables to ensure a precise power supply for the assemblies under test.

Applications

Power supply for PCBS or devices under test
Testing reserve polarity protection switches with negative voltages
Use as a constant current source
Loading outputs with a programmable current (electronic load)
Generating a single-phase supply voltage with variable amplitude and frequency up to 200 W with the use of a transformer (AC source)
Generating a three-phase supply voltage with 3 synchronised PSU boards with variable phase angles
