Chroma 62000D Programmable DC Power Supply and Load

The DC power supplies from the Chroma 62000D series are so-called bi-directional DC power supplies which function in 2 quadrants. With a positive output voltage, both a positive and a negative current can be programmed. (Source & Sink mode) This means that this 62000D series can be used as DC power supply, as DC load but also in the automatic, bi-directional mode. The regenerative concept ensures that in the event of a negative current (as a DC load), the absorbed energy is fed back into the AC grid with a conversion efficiency of up to 93%.

The Chroma 62000D bi-directional power supply is available in a 0 to 100V/0-600V/0-1200V/0-1800V version and can function as a cash voltage, current and power source (CV, CC, CP mode). Compared to a traditional power supply and load, the 62000D bi-directional DC power supply saves space, reduces energy loss and heat dissipation and is easy to configure. Powers up to 180kW are made possible by connecting multiple units in parallel in a master-slave configuration. The bi-directional power supply is ideally suited as a battery simulator. This makes it relatively easy to program conditions for the state of charge (SOC) or to load specific battery characteristic V-I curves. The intuitive touch screen and the intelligent front user interface reduce testing time and simplify complex test processes.

APPLICATIONS

The 62000D series bi-directional DC power supplies meet the increasing demand for suitable test and measurement set-ups for renewable energy sources such as PV, EV, fuel cells and batteries. After all, these are in the spotlight as replacements for traditional energy sources as well as the necessary, often bi-directional, energy conversion equipment. Bi-directional power supplies are therefore very suitable as battery emulators, for charge/discharge tests and life cycle tests, including BOBC, DC-DC conversion. PCS Motor driver testing for DC-AC power supplies in accordance with LV123 and LV148 standards for automotive components. But also I-V energy simulation testing of energy storage, battery and fuel cell in microgrid labs are part of the 62000D series.
