Electronic load offers increased power for testing fuel cells

As well as setting a new benchmark for power, the RBL 6000 also sets new standards for programmability, speed, frequency response and accuracy.

In the constant-current or constant-voltage mode, the Dynaload RBL 6000 is ideal for characterising the variations in power output with hydrogen flow rate in fuel cells. The pulse mode may be used to determine the effects of instantaneous current change, thus assisting in establishing stability under real-world conditions. With its high-speed response characteristics, the unit may be used to determine the output impedance of the fuel cell.

The new 6 kW series of loads are available in 100, 400 and 600 V ratings and are offered with IEEE488, RS232 and Ethernet communications. All RBL units are benchtop or standard 19-inch rack mountable and can be operated in parallel to achieve even higher power levels.
