Programmable High-Precision DC Power Supply

GW Instek PPX Series: Precise DC power for development, test, and measurement

The programmable high-precision DC power supplies of the GW Instek PPX Series include six models for demanding applications in development, testing, and quality assurance. Compared to conventional linear power supplies, they offer extremely low output noise of only 0.35 mVeff and very fast settling times of less than 50 microseconds.

Flexible output modes and dynamic control

The PPX Series supports priority output modes with constant voltage (CV) and constant current (CC). Voltage and current rise and fall rates can be configured independently. In addition, the delay time for output on and off can be set individually. This allows precise adaptation to dynamic load profiles and sensitive devices under test.

High-resolution measurement functions and data logging

For high-precision measurements, the power supplies provide four selectable current ranges and two voltage ranges. This multi-range design improves resolution and measurement accuracy across a wide operating range. The integrated data logger function enables output of measurement data via the USB interface. This makes the PPX Series ideal for long-term measurements and continuous recording, for example with IoT devices, portable electronic systems, and sensor components.

Alternative Products

Do you need two channels and precise measurement of fast pulse currents? Then we recommend the PPH-15xxD Series, offering high measurement resolution and pulse-current measurements down to 33 µs. If you require significantly higher voltage or power, we recommend the PSW Series with up to 800 V and 1,080 W, while the PPX Series remains the better choice for high-resolution, low-noise measurements.
