Functions & Advantages

Bidirectional Current, Combines Power and Feedback Load Features

N35200 series combines power and feedback load features. DC Sourcecan not only provide external power, but also absorb power, and returnelectric energy to the grid cleanly. N35200 series bidirectional powersupply can be converted continuously seamlessly between the outputand absorbed current, effectively avoiding voltage or current overshoot.It is widely used in power battery, UPS, battery protection board andother energy storage equipment testing.

Wide range of output design

N35200 series bidirectional DC power supply adopts a wide range design.A single power supply can output a wider range of voltage and current underthe rated output power, satisfying engineers' test application scenarios forproducts of various voltage/current levels, and greatly reducing power costand space occupancy in laboratory or automated test systems.

CC&CV priority function

N35200 series has the function of setting voltage loop feedback circuit priority or current loop feedback circuit priority, it canadopt the optimal working mode for testing according to the characteristics of DUT, so as to better protect DUT.As shown in Figure 1, when need to reduce voltage overshootduring testing, the voltage priority mode should be used inorder to obtain a fast and smooth rising voltage.As shown in Figure 2, when need to reduce current overshootduring testing, the current priority mode should be used toobtain a fast and smooth rising current.

Master/slave design, convenient for power expansion

N35200 can be used independently or in master/slave parallel operation. It has built-in master/slave mode, and the Max.power can be expanded to 1.8MW. It adopts a unique current sharing design to ensure each module shares the loadequally and ensure the consistency of product use.
