功能与优势
Flippable Front Panel and Color Touch Screen
This series High Power DC Load is equipped with flippable front panel for 4U, 7U, 10U and 13U height models. Together with a large color touch screen provides simple and fast operation for customer. Real-time update of display input data, status and graphical display makes it more intuitive.
Multiple Operating Mode
Basic Operating Mode
This series High Power DC Load provides four kinds of basic operating mode including CV (constant voltage), CC (constant current), CR (constant resistance), CP (constant power), to satisfy a wide range of test requirements.
Adjustable CV Loop Speed
This series electronic load supports CV loop response speed setting to FAST, NORMAL or SLOW to satisfy different test requirements.This function may avoid the inaccurate measurement or testing fail caused by the response speed mismatch between the load and the power supply, which is possible to improve test efficiency and reduce costs on the equipments, time and expenses.
Dynamic Load
This series electronic load can be switched quickly between different values in the same operating mode, including CC dynamic mode, CV dynamic mode, CR dynamic mode and CP dynamic mode, CC/CR high speed dynamic mode up to 50kHz. This function is suitable for transient test of power supply, test of battery protection characteristic and battery pulse charging etc. Dynamic mode test has continuous mode, pulse mode and toggle mode.
Maximum power point tracking (MPPT)
It can be applied to track the maximum power point of solar panels. Through the maximum power point tracking method, the maximum power point of the solar panel can be dynamically searched all the time, which can maximize the effectiveness of solar panels.
RLC
Simulating capacitive loads makes the current draw closer to the real situation. It is mainly applied for simulating capacitive loads turn on and turn off test. It can prevent the power supply from charging the capacitors on the motherboard when the power is turned on suddenly, which will cause the inrush current to trigger the power supply over-current protection and make the power supply fail to start smoothly.
Battery Discharge Test
This series electronic load has battery discharge function, and can perform discharge test under CC, CR or CP mode. The DC load can set end volatge or time to stop loading correctly and make sure the battery is not damaged due to over discharge. The user can set stop conditions, whenever met any condition, the load will stop loading and counting automatically. During the test, users can observe battery's voltage, discharging time and already-discharged-capacity.
