The PEL-500 series single channel electronic load has 5 models, each providing a voltage operating range of 0-80V/O-500V and a power operating range of 250-700W. It can be applied to research and development, quality control, ATE systems, and production testing, including voltage/current source testing, instantaneous response of switching power supplies, constant voltage mode supply and current limiting testing, and simulated battery and battery discharge testing. The PEL-500 series provides a display of 5-digit voltage, current, and power, allowing users to simultaneously monitor the measurement data of the test object. For the convenience of users in evaluating the test substance Can it withstand unbalanced current? The PEL-500 series provides Surge testing, which can simulate startup overshoot current and instantaneous current during hot insertion. The built-in battery discharge testing function can determine the conditions for stopping discharge according to the testing requirements of the test object, 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 according to the characteristics of the test object for testing. When the output voltage of the test object rises to the loading voltage value, loading begins. When the output voltage drops to the unloading voltage, unloading begins. Users can use the GO/NG function to pre-set judgment conditions based on the functions and specifications of the test object. The PEL 500 series will automatically generate judgment results during the testing process according to the set judgment conditions. Under the safety testing requirements of the power supply, the PEL-500 series not only provides Short testing function, but also automatic testing function for overcurrent protection/overpower protection, simplifying the tedious manual operation for users to verify the OCP/OPP action point of the tested object. The measurement results generated help users confirm whether the actual action point of the test object in OCP/OPP is within the measurement specifications. The PEL-500 series can provide load current waveform to the oscilloscope through Imonitor's BNC output terminal; It also provides overvoltage, overcurrent, overpower, and overtemperature protection, as well as reverse polarity detection. When any of these trigger actions, the PEL-500 series will have protective or reminder measures to protect the PEL-500 from damage due to abnormal operating range.
