The Instek GPP-7250G Single-Channel Programmable DC Power Supply with GPIB provides high programming resolution (2mV/0.2mA) and readback resolution (0.1mV/0.1mA), and the best low ripple noise characteristics ≦1mVrms ( 5Hz~ 1MHz) / ≦2mArms and output transient recovery capability≦100us.

It provides a variety of display modes, including channel setting values, measurement values, and waveform display. Using the output monitoring function of the GPP series, users can set monitoring conditions according to their needs, generate an alarm or stop output during the measurement process, stop the measurement and protect the customer's DUT. The GPP series provides an output recorder function, the voltage/current of the output process can be recorded in the internal memory, and the results can be saved as (*.REC) or (*.CSV) file and transferred to a USB. The saved *.CSV can be later exported into Excel for analysis.

The GPP-7250G is designed with a load function of up to 100W. The GPP-7250G provides 72V/5A power output, and has built-in maximum 72.5V constant voltage load (CV), maximum 5.2A constant current load (CC) and maximum 1kΩ constant resistance load (CR) functions.

The output of the GPP-7250 provides the sequence output function, which not only allows users to edit the power output waveform, but also allows users to set a sequence of constant voltage (CV) or constant current (CC) load waveform. For example, sequential power output or dynamic load simulation testing. In order to simplify the settings of waveform editing, the GPP series has 8 built-in waveforms in the templet waveform from the sequence output function, including Sine, Pulse, Ramp, Stair Up, Stair Dn, Stair UpDn, Exp Rise, Exp Fall waveforms, providing users to apply for output directly.

The complete protection functions comprise OVP, OCP, OPP, and OTP. The protection mechanism of OVP, OCP, and OTP is implemented by hardware circuits. Compared with competitors that use software to implement protection, it has the advantage of fast response time. The OVP and OCP functions allow users to set the protection action point based on the conditions of the DUT. OPP only protects the operation of the load function. The delay function can set the length of time during which the power output is on or off.

In addition, the Trigger In/Trigger Out function can synchronize external devices. The intelligent temperature-controlled fan can adjust the speed according to the temperature of the power transistor to reduce unnecessary noise. The output value setting and Sequence/Delay/Recorder functions respectively provide 10 sets of internal storage memory, and can be exported/stored using a USB. In addition to standard LAN, RS-232 and USB remote interfaces, the GPP-7250G also has GPIB interface to meet different user needs.
