Single-Channel Programmable DC Power Supply

GWI GPP 3610H16 January 2024 - The GPP programmable DC power supply series of GW Instek incorporates two new 360W models, namely the 36V/10A GPP-3610H and the 72V/5A GPP-7250. GPP-3610H. The GPP-3610H provides high programming resolution (1mV/0.2mA) and readback resolution (0.1 mV/0.2 mA); GPP-7250 provides high programming resolution (2mV/0.2mA) and readback resolution (0.1 mV/0.1 mA), and the best low ripple noise characteristics 1 mVrms ( 5 Hz, 1MHz) / 2 mArms and output transient recovery capability of 100 us.

The GPP-3610H and GPP-7250 provide 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.

GPP-3610H and GPP-7250 are designed with a load function of up to 100 W. The GPP-3610H provides 36 V/10 A power output, and has built-in maximum 36.5 V constant voltage load (CV), maximum 10.2 A constant current load (CC) and maximum 1 kΩ constant resistance load (CR) functions. GPP -7250 provides 72 V/5 A power output, and has built-in maximum 72.5 V constant voltage load (CV), maximum 5.2 A constant current load (CC) and maximum 1 kΩ constant resistance load (CR) functions.

The output of GPP-3610H and 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, GPP-3610H and GPP-7250 also have optional GPIB interface to meet different user needs.
