Functions & Advantages

Bidirectional current, seamless switch between source and load
N35100 series DC source can not only provide external power, but also absorb power, and return electric energy to the grid cleanly. N35100 series bidirectional power supply can be converted continuously seamlessly between the outpt and absorbed current, effectively avoiding voltage or current overshoot .It is widely used in li-ion battery, UPS, battery protection board and other energy storage equipment testing.

source and load seamless switch

Wide range of output design
N35100 series bidirectional DC power supply adopts a wide range design. A single power supply can output a wider range of voltage and current under the rated output power, satisfying engineers' test application scenarios for products of various voltage/current levels, and greatly reducing purchase cost and space occupancy in laboratory or automated test systems.The output power of the N35125-80-55 is 2500W. Maximum output voltage and output current reach 80V and 55A respectively,and a power supply can cover more applications for saving cost.

CC&CV priority function
N35100 series has the function of setting voltage loop feedback circuit priority or current loop feedback circuit priority, it can adopt 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 overshoot during testing, the voltage priority mode should be used in order to obtain a fast and smooth rising voltage.As shown in Figure 2, when need to reduce current overshoot during testing, the current priority mode should be used to obtain a fast and smooth rising current.
