N6112 Series Multi-channel Programmable DC Electronic Load
N6112 series is developed based on NGI's years of experience in testing for power supply and battery. It is with high accuracy, high reliability, high integration, high cost-effective and full features in CC, CV, CP, and CR. N6112 series is tailored for integrated applications, featuring fast communication speed and high stability. In most integrated applications, N6112 series can replace low-power standalone electronic loads and save much cost for users.
N6112 series is specifically designed for embedded integrated applications, with 19-inch 3U size and LAN port, and providing drive program. It supports secondary development of most software, such as Visual C ++, C #, Delphi, Visual Basic, Labview, etc. Users can customize the application software as needed.

OCP (over current protection) test
OCP test function increases the load current gradually until the current limit protection occurs to the DUT. The maximum actual current value before the measured current (voltage) drops is the current limit protection value.
Readback speed up to 10ms , multi-channel centralized control
N6112's multi-channel readback interval is up to 10ms. When applying N6112 to test the dynamic performance of the DUT, it can capture the transient process of the DUT and make test of such as fuse short-circuit or blowout.
Dynamic frequency sweep
Dynamic frequency sweep is similar to transient mode, repeatedly switching between two parameters. The duration of each parameter is determined by the sweep frequency and duty ratio. It increases from the initial sweep frequency to the cut-off frequency. The frequency increment and frequency point sweep duration are settable. During the sweep, the input voltage is accompanied by a current transient, which causes overshoot and drop. With the functions of voltage ripple and peak-to-peak measurement, various dynamic parameters and corresponding frequencies can be obtained.
Programmable slew rate
Rising and falling slew rates are settable to prevent overshoot and meet the complex test demands.
The Von latch function has two modes to meet your various test needs : enabled and disabled.
Ultra-high integration, single device with up to 12 channels
N6112 series supports up to 12 channels in a single device. Each channel is isolated, available for independent application or integration in a cabinet. The ultra-high integration makes N6112 an optimal selection for multi-channel batch test applications.
Remote sense to improve measurement accuracy
Remote sense is also four-wire sense. When N6112 is working, it will cause a voltage drop in the leads between the DUT and terminals of N6112, which will affect the voltage measurement accuracy of the load. When working under CV, CR and CP mode, to ensure accurate measurement, it is recommended to use remote sense. During remote sensing, terminals S + and S- are directly connected to the output of the DUT, eliminating the voltage drop in the leads.

Typical application-Automotive fuse blowout test
Automotive fuse test is regarding the safety of automotive control circuits. There are mainly two test items : fuse short circuit test and fuse over current test. Both tests need to record the time, current and voltage of the fuse blowout and the waveform of the blowout process.
Advantages of N6112 in fuse test
■ Stable and reliable operation without failure for long time over-current test
■ Readback speed up to ms-level, short-circuit test waveform without distortion
■ Convenient control via LAN port; Single device with up to 12 channels, reducing communication wiring
■ High cost-effective
Multi-functional application software
N6112 provides application software, which can monitor the operating state of all channels in real time, including voltage, current, and power. Users can view the configuration information by selecting a specific channel. Meanwhile, all data will be saved into a database for future review.
