The PEL-500 series single-channel electronic load has a total of 5 models and provides 0~80V/ 0~500V voltage operating ranges
and 250~700W power operating range. The series can be applied to R&D, quality control, ATE system and production test,
including voltage source/current source test; switching power supply transient response; constant voltage mode for current limiting
test; battery simulation; and battery discharge test.
The PEL-500 series provides a 5-digit digital display of voltage, current and power. Users can monitor the measurement data of the
DUT at the same time. In order to facilitate users to evaluate whether the DUT can withstand the overshoot current, the PEL-500
series provides Surge test, which can simulate the boot overshoot current and the transient current from hot plugging. The built-in
battery discharge test function can determine the conditions for stopping the discharge according to the test requirements of the
DUT, including setting the discharge stop voltage (Vbatt), discharge capacity (AH, WH) and stop discharge time.
Users can set the loading voltage/unloading voltage of the PEL-500 series for testing according to the characteristics of the DUT.
When the output voltage of the DUT rises to the loading voltage value, the loading starts. When the output voltage drops to the
unloading voltage, the loading ends. Users can use the GO/NG function to pre-set the judgment conditions according to the
function and specifications of the DUT. The PEL-500 series will automatically generate the judgment results according to the set
judgment conditions during the test.
Under the safety test requirements of the power supply, the PEL-500 series not only provides the Short test function, but also
provides the automatic test function of overcurrent protection/overpower protection to simplify users’ complicated manual
operation and verify the OCP/OPP of the DUT’s action points. The generated measurement results help users confirm whether
the actual operating action points of the DUT for OCP/OPP are within the measurement regulations.
In addition to the function of providing load current waveforms to the oscilloscope via the BNC output terminal of Imonitor, the
PEL-500 series also provides overvoltage, overcurrent, overpower and over temperature protection, and reverse polarity detection.
When any one of them generates a trigger action, The PEL-500 series will have protective or reminding measures to protect the
PEL-500 series from damage due to abnormal operating ranges.
