IT6400 Series Bi-Polar DC Power Supply

Click2Contact

The bipolar voltage/current power supply IT6400 series can be used as both a power source and an electronic load which is suitable for battery charge/discharge tests.

The IT6412 is a dual-channel power source which can output up to ±15 V at up to ±3 A or ±9 V at up to ±5 A. The IT6411 and IT6432 are the single-channel type and the IT6432 extends the output voltage to ±30 V with power up to 150 W. The IT6411S is an updated version of the IT6411 that can monitor load currents to 10 nA, which is more suitable for testing atomic scale current or dark current. The IT6431 extends its output current to ±10 A to meet the latest quick-charger test requirement or to simulate the latest USB-C output.

The series can not only charge/discharge a battery by setting shut-off conditions including voltage, current, capacity and time, but also simulate a battery with settable internal resistance. The user can import a list of the battery’s parameters, including voltage, remaining capacity and resistance, to simulate a battery’s charge/discharge procedure while monitoring the SoC, remaining capacity, resistance, open-circuit voltage, voltage and current.

To monitor fast changing and pulse-like load currents properly, the series offer the speed necessary to capture load changes that occur at intervals as short as 50 µs when 50–100% loaded. This allows designers and manufacturers of portable, battery-operated devices to monitor load currents easily in all of a device’s operating modes. Speed shift mode achieves voltage/current high-speed rising waveform without overshoot, supports stable power supply and ensures security, especially for LED testing.

Abundant electrical basic measuring functions are available. High-precision DVM is built into each channel, with readback resolution up to 1 mV and the measured data visible on each channel screen. The waveform of voltage/current display function lets the test be visible and simple.
