The Instek PEL-504-500-15 Single-Channel Programmable DC Electronic Load provides a power rating of 350W, maximum output voltage of 500V and maximum output current of 15A. It 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-504-500-15 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-504-500-15 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-504-500-15 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-504-500-15 will automatically generate the judgment results according to the set judgment conditions during the test.

Under the safety test requirements of the power supply, it 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-504-500-15 also provides overvoltage, overcurrent, overpower and over temperature protection, and reverse polarity detection. When any one of them generates a trigger action, the PEL-504-500-15 will have protective or reminding measures to protect it from damage due to abnormal operating ranges.
