The EL4900 provides simultaneous voltage and current measurement capabilities. Measurements can be made using two main modes: averaged or digitized. In average mode, the EL4900 delivers accurate voltage and current measurements. The digitizing capability allows you to capture dynamic current or voltage profiles.

In addition to voltage and current measurement capabilities, the EL4900 Series regenerative electronic load offers built-in power, amp-hour, and watt-hour calculations. These measurements help simplify your power efficiency and storage calculations.

The EL4900 returns 95% of the energy it absorbs to the grid cleanly, saving costs on energy consumption and cooling while not interfering with the grid. When sinking current, the EL4900 automatically returns excess power to the grid, with no programming required. To safeguard your Device Under Test (DUT), the EL4900 automatically senses that the grid is live, detects phase voltage and frequency in real time, and synchronizes safely before regenerating power to the grid.

With efficiency of more than 85%, the EL4900 lowers energy use and heat dissipation when sinking, cutting air conditioning requirements. Additionally, it helps reduce carbon emissions and their impact on the environment.
