The Chroma 63700 Series is a state-of-the-art regenerative load specifically designed for testing inverters and off-grid systems. The series is suitable for product reliability testing in various applications including electric vehicle (EV) battery discharge, fuel cell discharge, aging of high power supplies, DC-EV supply equipment (EVSE), unidirectional on-board chargers (OBC), fuel cell systems, energy storage systems (ESS), AC/DC and DC/DC power supply burn-in testing and various power electronics applications.
The 63700 series offers a unique combination of high power density, superior efficiency and precise measurement capability. It can operate in various modes including constant current, constant voltage, constant power and constant resistance to meet a variety of test requirements. With its regenerative technology, it feeds the energy generated during the test process back into the power grid, resulting in significant energy savings.
The regenerative loads feed much of the energy generated during the test process back into the power grid instead of losing it as heat. This results in significant energy savings and reduces the need for expensive and polluting cooling systems.
The 63700 series loads are available in different power classes and can be operated in both single and multi-phase configurations. They offer a variety of operating modes, including constant current, constant voltage, constant power and constant resistance, to meet a wide range of test requirements.
The Chroma 63700 series is equipped with an intuitive user interface and extensive remote control options that allow easy integration into automated test systems. With its robust design and high reliability, the Chroma 63700 series is the ideal choice for demanding power electronics applications.
