Функције и предности
OCP (over current protection) test
During OCP test, N6112 will load under CC mode and check whether the DUT voltage is lower than end voltage. If lower,N6112 will record the present loading current as the test result and shut the input to stop the test. If the DUT voltage ishigher than end voltage, N6112 will increase the loading current until the DUT voltage is lower than end voltage or itreaches the Max. loading current.
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 scenes 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 ofeach parameter is determined by the sweep frequency and duty ratio. It increases from the initial sweep frequency to thecut-off frequency. The frequency increment and frequency point sweep duration are settable. During the sweep, the inputvoltage is accompanied by a current transient, which causes overshoot and drop. With the functions of voltage ripple andpeak-to-peak measurement, various dynamic parameters and corresponding frequencies can be obtained.
Programmable slew rate
Rise and fall slew rates are settable to prevent overshoot and meet the complex test demands.
The conversion slew limits the current or voltage transition rate when the on-load main value of N6112 changes. When the slew is set to the maximum value, the transition time between the main value and the transient value is minimal.
The Von latch function has two modes to meet your various test needs: enabled and disabled.
Ултра-висока интеграција, један уређај са до 12 канала
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 a competitive selection for multi-channel batch test applications.
Remote sense to improve measurement accuracy
Remote sense is also known as four-wire sense. When N6112 is working, it will cause a voltage drop in the leads betweenthe 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
● Sampling rate 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 performance
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.
