The GPP-1000 series is a high-precision programmable DC power supply, featuring voltage resolution of up to 1 mV / 0.1 mV and offering three levels of current resolution, with a maximum resolution of 1 μA / 0.1 μA to ensure accuracy in precision testing. The device supports both Constant Voltage (CV) and Constant Current (CC) modes, and includes a switchable power supply and electronic load function, making it suitable for a wide range of testing environments. The series includes two models: the GPP-1205 (20 V / 5 A / 100 W) and the GPP-1323 (32 V / 3 A / 96 W), offering flexible output power options.
 
GPP-1205: 100 W Single Channel Programming LinearDC Power Supply (USB, LAN)
GPP-1205 (GPIB): 100 W Single Channel Programming LinearDC Power Supply (USB, LAN, GPIB)
GPP-13239: 6 W Single Channel Programming LinearDC Power Supply (USB, LAN)
GPP-1323 (GPIB): 96 W Single Channel Programming LinearDC Power Supply (USB, LAN, GPIB)
 
 
The GPP-1000 series is equipped with built-in Remote Sense functionality, which compensates for voltage drops caused by lead resistance, ensuring accurate output. Additionally, the series offers data collection and logging capabilities, allowing users to track test data for further analysis. To enhance flexibility, the GPP-1000 series supports external series or parallel connections of up to four units, making it suitable for higher power testing requirements.
 
In terms of safety, the GPP-1000 series is equipped with built-in protections including OVP (Over Voltage Protection), OCP (Over Current Protection), OTP (Over Temperature Protection), and reverse polarity protection to ensure stable operation of both the device and the connected load. A front panel lock function is also provided to prevent accidental operation, enhancing operational safety. The communication interface supports USB-TMC/CDC and LAN, with optional GPIB available to meet remote control requirements. The series features a 2.4-inch TFT-LCD for clear data visualization, and is equipped with an intelligent temperature-controlled fan to effectively reduce noise and improve cooling efficiency.
 
Overall, the GPP-1000 series stands out as one of the most powerful programmable DC power supplies on the market, thanks to its high resolution, versatile communication interfaces, comprehensive safety protections, and flexible application modes. Whether used in R&D, testing, or production environments, it delivers stable and efficient power solutions to meet a wide range of user needs. This power supply not only enhances the technical capabilities of conventional equipment but also exemplifies the direction of modern test equipment development—making testing processes more accurate, convenient, and efficient.
