Functions & Advantages
Ultra-high integration, single device with up to 4 channels

N39400 series adopts the standard 19-inch 2U design, with Max.4 channels in a single device. Each channel is isolated.One device can support 4-station test simultaneously, which greatly reduces the test equipment quantity and improves test efficiency.

Remote control

N39400 series supports remote control, providing RS232 and LAN port to communicate with the computer, and realizing all functions on the panel via computer application software.

Remote sense

NN39400 series provides remote sense function, which can transfer the actual voltage of the load back to N39400 so that N39400 can compensate for the output voltage and eliminate lead wire errors.

UI flat icons offer convenient and quick operation.

CC&CV priority function

N39400 has the function of selecting priority of voltage-control loop or current-control loop, which enables N39400 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.

Dual LAN ports for multiple devices control
N39400 is equipped with two LAN ports, which can support multiple devices control for quick adjustment and test.
