The GPP- series of multi-channel programmable DC power supplies, with output power up to 385W, consists of six models: the single-channel output GPP-1326, the dual-channel output GPP-2323, the three-channel output GPP-3323, GPP-3060, GPP-6030, GPP-3650, and the four-channel output GPP-4323. This series not only provides independent output switching for each channel, but also offers 1mV/0.1mA setting resolution, low ripple noise characteristics ≦350uVrms/≦2mArms, and ≦50uS output transient recovery capability.
CH1 and CH2 are used in series and parallel, GPP-'s Tracking Function uses internal wiring to automatically switch the outputs into series or parallel outputs without the need for additional external wiring, providing the user with not only the convenience of the operating procedure, but also more stable outputs; it is the factory Tracking Function design, the outputs of the series or parallel outputs also The Tracking Function design requires additional external wiring, however, excessively long, thin, or inconsistent external wiring may result in inaccurate voltage or current output.
The GPP series provides up to 7 display modes (varying by model), including single-channel or multi-channel display of setpoints, measured values, and waveforms. The output monitor function of the GPP series allows users to set the test conditions according to their needs, generate alarms or stop the output during the measurement process to abort the measurement and protect the customer's object to be measured; the output recording function can 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 to load into Excel for analysis by themselves. The output record can be saved as (*.REC) or (*.CSV) files for users to import into PC software for graphical analysis or load into Excel for analysis.
GPP-CH1/CH2 is designed with Load function, a single power supply can meet the basic battery charge/discharge test, Channel 1 (Ch1) and Channel 2 (Ch2) not only provide power output, but also built-in constant voltage pull load (CV), constant current pull load (CC) and maximum 1KΩ constant resistance pull load (CR) function, so the user does not need to use an electronic load for the additional discharge test.
Channel 1 (Ch1) and Channel 2 (Ch2) of the GPP series provide a sequence output function, which not only allows the user to edit the power output waveforms, but also allows the user to set up a sequence of Constant Voltage (CV) or Constant Current (CC) pull functions. For example, sequential power output or dynamic load simulation test. In order to simplify waveform editing, the GPP series serial output function has built-in 8 common waveforms in the Templet waveform, including Sine, Pulse, Ramp, Stair Up, Stair Dn, Stair UpDn, Exp Rise, Exp Fall waveforms for users to directly call up the output.
Comprehensive protection functions OVP/OCP/OPP/OTP, of which the functional protection mechanism of OVP/OCP/OTP is realized by hard wiring, which has the advantage of fast response time compared with the competitors that use soft to realize the protection.The OVP/OCP function allows the user to set the protection action point (except CH3 of GPP-3323) according to the condition of the object to be measured.The OPP is only activated when the Load The Delay Function controls the length of time during which the power supply of Channel 1 (Ch1) or Channel 2 (Ch2) is or is not output.
In addition, Trigger In/ Trigger Out function can synchronize external devices; GPP-3323/3060/6030 channel 3 (Ch3) to add 3A USB (Type A) output terminal, can do USB charging test; Intelligent temperature control fan can be based on the temperature of the power device, adjusting the speed to reduce unnecessary noise. Output value setting and Sequence/Delay/Recorder functions provide 10 groups of memory for use, and can be loaded/stored using a USB flash drive.The GPP series comes standard with RS-232C and USB remote interfaces as well as optional LAN or LAN+GPIB interfaces, making it convenient for different user needs. The commands meet the requirements of SCPI and are compatible with the commands of the GPD-x303S series of DC power supplies.
