Autoranging Gives Flexibility

EA Elektro-Automatik products have autoranging, which allows the supply or load to operate at max power across a range of voltages and currents, down to 33% of the rated output maximum.

Compare this to traditional power supplies, which can only output their rated power at their max voltage and max current. Applying the maximum voltage to a device under test (DUT) is rare, which means most of the time, that supply is not being used to its full potential.

How does it work? EA sources automatically offer more current at lower voltages (or more voltage at lower currents), allowing the supply to continue outputting the rated power. This allows a single source to address multiple voltage and current combinations that would otherwise require multiple supplies.

Built-In Function Generator Simplifies Setups

Many EA supplies and loads include an integrated function generator that can be used to drive the voltage or current output. All the typical AFG waveforms are available as well as arbitrary capability with sequencing for creating more custom output waveforms. This AFG capability scales with multiple supplies in parallel.
The function generator allows the supply to simulate or test complex behaviors like:

• Simulating a solar cell with accurate open circuit voltage, short circuit current, and maximum power point (MPP) voltage and current.
• Testing inverter efficiency to CSN EN 50530 standards.
• Testing LV123, LV124 and LV148 standards for automotive suppliers.

Industrial Series for Most Demanding Power Needs

For the highest energy density needs and future-oriented applications, the EA-10000 Industrial Series is available. 6U form factors offer up to 60kW of power, and 19” rack solutions mean you can deliver 300kW of power from only 0.6 m2 of floor space. Combine up to 13 racks for 3.84MW of bidirectional power delivery and recovery. The industrial series are available as a unidirectional power supply (PU), bidirectional power supply (PUB), and regenerative electronic load (PUL).
