Chroma's 63218A series high power DC electronic loads with digital signal microprocessor built in have the optimal speed and control performance designed for testing a wide range of power conversion products. The 300% peak overpower capability provides extra headroom for fault condition simulations in automotive batteries, fuel cells, and more. The dynamic auto-frequency sweep function of the Chroma 63218A-150-1800 DC load enables detecting a UUTs worst case output deviation across a wide range of current frequencies. The Chroma 63218A-150-1800 electronic DC load offers high speed, programmable dynamic loading and sweep simulation for testing. Its super high voltage (0.015%+0.015%F.S.) and current (0.04%+0.04%F.S.) measurement accuracy ensures the fidelity of results. A 255-set of data storage function has been built in for recall of the stored settings at any time. For automated testing, the save and recall functions can save a great deal of time. The Chroma 63218A-150-1800 DC electronic load has 3 power ranges that can precisely measure the voltage and current in real time. These Chroma 63218A-150-1800 DC loads are reliable products for engineering testing and automated test system's integration.
