Bidirectional current, seamless switch between source and load
N35200 series DC source can not only provide external power, but also absorb power, and return electric energy to the grid cleanly. N35200 series bidirectional power supply can be converted continuously seamlessly between the output and absorbed current, effectively avoiding voltage or current overshoot. It is widely used in power battery, UPS, battery protection board and other 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 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.

CC&CV priority function
N35200 series has the function of setting voltage-control priority or current-control loop 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 it needs to reduce voltage overshoot during testing, the voltage priority mode should be used to obtain a fast and smooth rising voltage. As shown in Figure 2, when it needs to reduce current overshoot during testing, the current priority mode should be used to obtain a fast and smooth rising current.

Fast dynamic response
N35200 series can achieve seamless switch between current output and current sink. Take N35218-500-120 for example. The switch time from source 120A to sink 120A is less than 2ms as below figure.
