Controllable switching power supplies from the SPS series

Standard laboratory power supplies

Switch-mode power supplies with PFC (Power Factor Correction) are significantly lighter and cheaper than linear regulated laboratory power supplies. Of course, residual ripple and control behavior at 100% load change cannot compete with linear devices, but stable values are still achieved for most applications.

Adjustable switching power supplies from the HPS series

Laboratory power supply units with adjustable current limiter and remote control

The HPS series can be controlled with digital potentiometers on the front or analog via the remote control connection (rear). If required, one of 3 fixed voltages can be selected at the rear using a slide switch.

The power supply units also have overvoltage protection, which switches off the output immediately if a higher external voltage than set is detected at the power supply unit output.

Controllable and programmable switching power supplies from the PPS series

Laboratory power supplies with USB control or analog remote control

The PPS series can be controlled with software via the USB connection or, like the HPS series, with digital potentiometers on the front or analog via the remote control connection. If required, one of 3 fixed voltages can be selected on the rear using a slide switch.

The power supply units also have overvoltage protection, which switches off the output immediately if a higher external voltage than set is detected at the power supply unit output.

Controllable and programmable switching power supplies from the DPPS series

Laboratory power supplies with USB control or analog remote control

The DPPS series is the more powerful version of the PPS series. The features are otherwise identical. The 60 A version has an additional sense input.
