Laboratory power supplies of the DP-P series are particularly multifunctional and have a large number of digital connections. These devices are highly accurate and stable and thus particularly suitable for laboratory use.
Maximum values of the series:
600V / 300A / 9kW / ØPL = 0.76€/W
DP-PH series high voltage power supplies are a modification of the DP-P series laboratory power supplies for high-voltage applications at low currents. These power supplies offer all the advantages of the DP-P series optimised for voltages up to 12kV.
Maximum values of the series:
12kV / 5A / 5kW / ØPL = 2.12€/W
Laboratory power supplies of the DP-S series combine reliability and performance in a compact unit with a carrying handle.

800V / 200A / 6kW / ØPL = 0.96€/W
DP-H series programmable precision laboratory power supplies offer excellent stability and accuracy values and a wide range of analog and digital inputs and outputs. Ideal for high-precision measurements in the laboratory.
Maximum values of the series:
150V / 60A / 900W / ØPL = 0.85€/W
Auto-ranging high-precision laboratory power supplies of the DP-HA series offer almost the same accuracy values as the DP-H series as well as a remarkably wide V / A range with auto-ranging functionality. DP-HA Series laboratory power supplies are a perfect addition to any laboratory or training facility.
Maximum values of the series:
605V / 111A / 1.5kW / ØPL = 1.30€/W
