The PPX-Series programmable high-precision DC power supplies include six models, as shown in the chart below. This series has the output low noise (0.35mVrms) and fast transient response characteristics (<50µs) of conventional linear power supplies, and also provides constant voltage and constant current priority output modes. It 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.

Via the Data Logger function, 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, GW Instek has launched the PPX-Series with current measurement resolutions (0.1µA, 1µA, 10µA, 0.1mA) and voltage measurement resolutions (0.1mV, 1mV) to provide power for portable and wearable devices. When the device enters the sleep mode or the standby mode, the PPX series can still measure the subtle current changes of the DUT. The PPX-Series provides a Test Sequence function, which allows users to arbitrarily define output waveforms. The voltage rise or fall 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 PPX-Series, or a CSV file can be edited via computer and imported. The PPX-Series can also be remotely edited. In addition, the OCP Delay function allows users to flexibly adjust the time to enable the over-current protection according to the characteristics of the DUT. This helps 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-Series also supports temperature measurement. While collocating with a K Type Thermocouple, the temperature range can be measured from -200°C ~ +1372°C. Supported standard communication interfaces include USB, LAN, RS-232, RS-485 and optional GPIB interface. Display mode The PPX-Series has four display modes, namely 1) voltage and current 2) voltage, current and wattage 3) voltage, current and Sequence Test 4) voltage, current and temperature measurement, which are convenient for users to switch to different display modes according to test requirements. Voltage and Current Voltage, Current and Wattage Voltage, Current and Sequence Test Voltage, Current and Temperature Measurement Remote sensing The Remote Sensing function can be used to compensate for the voltage drop caused by the resistance on the test connection lead from the power output to the load. PPX-1005/2002/2005/3601/3603 compensates for voltages up to 1 volt, and PPX-10H01 compensates for voltages up to 3 volts. When testing, choose a test connection lead with a voltage drop less than the compensation voltage of the PPX series as much as possible. Temperature measurement The PPX series can measure DUT temperature while outputting power. Before measuring the temperature, please use the optional accessory GTL-205A (temperature probe adapter with K-type thermocouple) to connect the DUT and TC input terminals on the front panel of the PPX-Series respectively. During the measurement process, users can set the monitoring temperature for the DUT. Once the measurement temperature reaches the monitoring temperature value, the PPX-Series will stop the output. The PPX-Series can measure the temperature range of -200.0°C ~1372.0°C (-328.0°F ~2501.6°F). Users can choose the display unit as Celsius or Fahrenheit according to the requirement. Blue: Temperature Control on with no GTL-205A Connected Green: Output Safe is Activated and Output is on with GTL-205A Connected White: Temperature Control on with GTL-205A Connected Red: The Alarm of Short Circuit Occurs From Temperature Measurement Data logging The PPX series can record the measured voltage, current and temperature data to a USB flash drive or it can be remotely controlled to read the data. The data sampling interval is 0.1~999.9 seconds. Data Logger Function Save Data Log Into USB Disk Sequence testing The Sequence Test function allows users to plan the PPX-Series to execute a sequential power output. The PPX-Series will automatically execute the planned power output to the DUT to realize automated measurement. The PPX-Series can store 10 sets of edited Test Scripts in the internal memory and can also be connected to a USB flash drive to store Test Scripts in the USB flash drive. SEQ Run in Cycle Mode SEQ Stop in Cycle Mode Multiple unit connection The PPX series can connect up to 31 units. The PC is connected to the first unit of PPX through GTL-260, and the remaining PPX units are connected in a daisy-chained method via GTL-262. When using PPX series Multiple Unit Connection for remote program control and slave expansion, there is no need to use other remote control equipment (E.g. switch/Hub), which can help users save equipment purchase costs.
