Wide range for saving purchase cost

N38300 series’ maximum power is not the result of Max. voltage multiplied by Max. current. Let’s take model N38306-300-75 for example. The Max. power is 6kW while Max. voltage 300V and Max. current 75A. Compared with traditional power supply, this feature offers N38300 wider application range, which significantly reduces the purchase cost and space occupation.

CC&CV priority function

N38300 has the function of selecting priority of voltage-control loop or current-control loop, which enables N38300 to adopt the optimal test mode for different DUTs, and thus protect the DUT.

As shown in figure one, when the DUT requires reducing voltage overshoot during test, such as supplying power to a low-voltage processor or FPGA core, voltage priority mode should be selected to obtain fast and smooth rise voltage.

As shown in figure two, when the DUT requires reducing current overshoot during test, or when the DUT is with low impedance, such as battery charging scenario, current priority mode should be selected to obtain fast and smooth rise current.

Internal resistance simulation

N38300 series allows settings of voltage and internal resistance value. According to the corresponding output current, the output voltage is decreased with the set resistance. In this case, the internal resistance of secondary battery, fuel cell and supercapacitor can be simply simulated.

Master/slave design, convenient for power expansion

N38300 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 load equally and ensure the consistency of product use.
