The GPP-series multi-channel programmable DC power supply has an output power of up to 385W, and includes six models: a single channel output GPP-1326, a dual channel output GPP-2323, a three channel output GPP-3323, GPP-3060, GPP-6030, and a four channel output GPP-4323. This series not only provides independent output switches for each channel, but also provides 1mV/0.1mA set resolution, low ripple noise characteristics ≤ 350uVrms/≤ 2mArms, and ≤ 50uS output transient recovery capabilities.
Using CH1 and CH2 in series and parallel, GPP's Tracking Function uses internal circuitry to automatically switch the output to series or parallel output, without the need for additional external wiring, providing users with not only convenience in operating procedures, but also more stable output; Other factory's Tracking Function design requires additional external wiring connections for series or parallel outputs. However, excessively long, thin, or inconsistent external wiring may cause inaccurate voltage or current output.
The GPP series provides up to 7 display modes (different models have differences), including single channel or multi-channel set values, measured values, and waveform display. Using the GPP series output monitoring function (Monitor), users can set test conditions based on their needs, generate alarms or stop output during the measurement process, suspend measurement, and protect the customer's objects to be measured; The output recording function can be used to record the output voltage and current of the GPP series into (*. REC) or (*. CSV) files for users to import into PC software for graphical analysis or load into Excel for analysis.
The CH1/CH2 of GPP - is designed with a load function. A single power supply can meet basic battery charging and discharging tests. Channel 1 (Ch1) and Channel 2 (Ch2) can not only provide power output, but also have built-in constant voltage pull (CV), constant current pull (CC), and maximum 1K Ω constant resistance pull (CR) functions. Therefore, users do not need to additionally use electronic loads for discharging tests.
GPP series channels 1 (Ch1) and 2 (Ch2) provide a sequential output function (Sequence). This function not only allows users to edit the power output waveform, but also allows users to set sequential constant voltage (CV) or constant current (CC) pull functions. For example, sequential power output or dynamic load simulation testing. In order to simplify waveform editing, the GPP series sequential output function includes eight common waveforms built into the Template Waveform, including Sine, Pulse, Ramp, Stair Up, Stair Dn, Stair UpDn, Exp Rise, and Exp Fall waveforms for users to directly call and output.
Perfect protection function OVP/OCP/OPP/OTP. The functional protection mechanism of OVP/OCP/OTP is implemented using hardware circuitry, which has the advantage of fast response time compared to competitors that use software to achieve protection. The OVP/OCP function allows users to set protection action points (except CH3 of GPP-3323) based on the conditions of the object to be measured. OPP is only activated when the load function is operating. The Delay Function can control the length of time during which the channel 1 (Ch1) or channel 2 (Ch2) power supply is output or not output.
In addition, the Trigger In/Trigger Out function can synchronize external devices; GPP-3323/3060/6030 channel 3 (Ch3) adds a 3A USB (Type A) output terminal for USB charging testing; Intelligent temperature controlled fans can adjust the rotational speed based on the temperature of power devices to reduce unnecessary noise. The output value setting and Sequence/Delay/Record functions provide 10 sets of memory for use, and can be loaded/stored using a USB flash drive. In addition to the standard RS-232C and USB remote interfaces, the GPP series also has an optional LAN or LAN+GPIB interface, which is convenient for different user needs. The instructions comply with the requirements of SCPI and are compatible with GPD-x303S series DC power supply instructions.
