PEL-5000G Series High Power DC Electronic Load

GW Instek PEL-5000G series single-channel electronic load provides 150V/ 600V/ 1200V models with a power range of 4kW~6kW. PEL-5000G has a total of 9 models featuring different combinations of power, voltage, and current. It can test and verify the specifications of batteries, electric vehicle chargers/charging stations and electric vehicle batteries. PEL-5000G supports parallel connection for same voltage specification and different power models. PEL-5000G can support up to 8 units connected in parallel to provide a maximum power of 48kW.

For the scenario of Battery Charger testing, PEL-5000G specifically provides four battery discharge modes, namely CV+Current Limit test mode, CV+Power Limit test mode,  CC mode and CP mode. Users can choose a suitable test mode according to the test requirements.

For Battery Discharge Function, users can set the discharge cut-off voltage, discharge time, or discharge capacity (Ah) in CC or CP mode to meet the battery testing requirements.

In order to meet the verification requirements of different DUTs, PEL-5000G provides a variety of test functions, Surge current test mode, automated OCP, OPP test functions and 150 sets of parameter storage function. The 1200V model of PEL-5000G not only provides full power output at 1000V, but also provides 60% power output at 1200V output, which is higher than the 50% power output of other manufacturers of similar electronic loads.

High-voltage batteries or chargers directly connected to the electronic load may cause damage to the electronic load. PEL-5000G has a built-in slow starter, which not only protects the DC load, but also saves the user's installation cost and setting time for measurement on 600V/1200V models.

The communication interfaces supported by PEL-5000G include GPIB, RS232, USB, and LAN. The power, voltage and current of each model are shown in the following table:
