Save costs through efficient energy conservation
Automatic range achieves flexibility
The EA Elektro Automation product has an automatic range function, which allows the power supply or load to operate at power within a certain voltage and current range, achieving 33% of the rated output.
In contrast, traditional power sources can only output rated power at voltage and current. However, it is rare to apply voltage to the device under test (DUT), which means that in most cases, the power supply has not fully realized its potential.
What is the working principle? EA power supply can automatically provide higher current at lower voltage (or higher voltage at lower current), allowing the power supply to continuously output rated power. Therefore, only one power source is needed to provide multiple voltage and current combinations, otherwise multiple power sources would be required.
Feedback converts energy dissipation into energy savings
The EA feedback electronic load and bidirectional power supply can recover 96% of the consumed electrical energy, which means that the AC power connection can also be used as a feedback output for the supplied DC electrical energy.
Traditional electronic loads or resistor groups dissipate power by converting the consumed electrical energy into heat. This may require large-scale cooling/HVAC solutions, and the energy consumed will be permanently lost as waste, thereby reducing the efficiency of testing and facilities.
The energy recovered by the EA load is fed back to the local facility grid through an inverter synchronized with the main power supply, for use by other devices within the facility. If the recovered energy exceeds the energy used by the facility (as may occur during testing of fuel cell output), the energy can be fed back to the public grid.
