Functions & Advantages
Channel parallelism and multi-power combinations
The N61200 series supports parallel connections between channels. By paralleling channels (e.g., CH1+CH2, CH3+CH4), users canachieve the desired current and power levels. Parallel settings and operations can be easily performed via master computer software or the device interface.
Multiple operation modes
N61200 series not only supports four basic modes of CC, CV, CP, and CR, but also supports four combined working modes of CV+CC,CR+CC, CV+CR, CP+CC, CR+CC mode is suitable for power-on test of source, preventing over current protection during power-on.CV+CR mode can replace Von function. CV+CC mode can simulate the working mode conversion process of battery charging. Userscan select different operation modes according to their test application.
LED light simulation to test LED driving power
The electronic load has LED light simulation function.As shownin the figure, the LED equivalent circuit is to connect theresistance Rd with the voltage source Vf in series. Its I-V curveis equivalent to tangent of the real LED nonlinear I-V curve atthe operating point (Vo, Io).As the I-V curve of LEDs is non-linear,conventional electronic loads with CR or CV modes do not matchthe testing needs of LED power supplies, so more sophisticatedload models are needed to simulate the behaviour of LEDs.Under LED mode, users need to set three parameters to simulatereal LED light loading condition, including the rated output currentof LED driving power, LED operating voltage, and resistancecoefficient.
OCP (over current protection) test
During OCP test, N61200 will load under CC mode and check whether the DUT voltage is lower than end voltage. If lower, N61200 willrecord the present loading current as the test result and shut the input to stop the test. If the DUT voltage is higher than end voltage,N61100 will increase the loading current until the DUT voltage is lower than end voltage or it reaches the Max. loading current.
