The Instek PPX-2005 (20V/5A/100W) programmable high-precision DC power supply has the output low noise (0.35mVrms) and fast transient response characteristics (<50μs) of conventional linear power supplies. It also provides constant voltage and constant current priority output modes, and the PPX2005 can also set the voltage and current rising/falling slew rates separately, and the delay time for the output to be turned on and off.

The PPX-2005 has four current levels and two voltage levels to provide users with high-precision measurements, and via the Data Logger function, the measurement records can be stored in the USB for long-term measurement and recording of IoT devices, portable devices, wearable devices, and sensor components.

In order to extend the use time of portable devices and wearable devices, manufacturers are not only committed to improving the operating efficiency of the circuit, but also reducing standby power consumption as much as possible. In order to satisfy users' low-power measurement applications, the PPX-2005 features current measurement resolutions (0.1μA, 1μA, 10μA, 0.1mA) and voltage measurement resolutions (0.1mV, 1mV) to provide power for portable devices and wearable devices. When the device enters the sleep mode or the standby mode, the PPX-2005 can still measure the subtle current changes of the DUT.

The PPX2005 provides the Test Sequence function, which allows users to arbitrarily define output waveforms. The voltage rising or falling time and the voltage maintenance time of each step can be set. For the operation, users can directly edit parameters on the front panel of the unit, or the CSV file can be edited via computer and imported into the unit, and the PPX-2005 can be remotely edited. In addition, the OCP Delay function of the PPX-2005 allows users to flexibly adjust the time to enable the over-current protection according to the characteristics of the DUT to protect the DUT and at the same time to test the current change of the DUT within a certain period of time.

Other than voltage, current, and power measurement, the PPX-2005 also supports temperature measurement. While collocating with a K Type Thermocouple, the temperature range can be measured from -200°C to +1372°C. Supported standard communication interfaces include USB, LAN, RS-232, RS-485 and optional GPIB interface.
