Monitors individual cell voltages of an operating fuel cell stack. This compact module may be operated stand-alone, or with a host PC. The 896 is also useful for other series-connected voltage sources or energy consuming devices such as batteries. Includes StackMon software for Windows.
The Series 896 may be used as a standalone component of the stack or may be host-controlled by a supervisory computer. Connector interface boards can be customized for the mechanical details of the stack used to allow the Series 896 to interface to a wide variety of stack designs.
A WindowsTM 32-bit host software package is included to optionally perform reporting, control, and data logging functions.
The 896 is an intelligent, digital, electronic monitor designed specifically for monitoring fuel cell stack performance and operating parameters. Completely self-contained, the 896 may be built right into the stack, resulting in a lower per-cell cost.
