ELECTRONIC LOAD


ELS-304 Electronic Load
ELS-304 Electronic Load is an electronic load capable of creating ultra high-speed slew rate for applications requiring high-speed dynamic load effect.
Our newly developed electronic load circuits implemented in the ELS-304 enables the internal parasite impedance to decrease and the bandwidth and the slew rate to be remarkably improved, realizing as fast as 200A/us (four times faster than our conventional products) even in a low voltage presented.
In addition, since ringing of load effect is minimized and it is possible to start operating just near zero volt., you can use the ELS-304 electronic load for evaluating the dynamic load effect of VRM and POL power supplies. And because the slew rate of rising and falling waveforms can be finely setup, you can use the ELS-304 for the current interrupt testing for fuel cells, etc.
