N6112 Series Multi-channel Programmable DC Electronic Load
■ Power range: 150W×12CH
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 is higher than end voltage, N6112 will increase the loading current until the DUT voltage is lower than end voltage or it reaches 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 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
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 theslew is set to the maximum value, the transition time between the main value and the transient value is minimal.
Settable Von/Voff
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
Remote sense to improve measurement accuracy
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
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.
