Operation control software
Stable software being used in various industrial applications
Automatic forwarding of testing items
Excellent performance to noise
Reduction of CPU load
Exclusive software part for fuel cell
The software changes process conditions by sequencing numbers of sheets writing test. After judgment of stability, it automatically collect data.
(Electronic load unit control)
(1) Initial activation automatic operation
(2) Load current sweep test=Tafel test
Electronic load (several hundred W to several hundred kW)
As a bias power supply corresponding to 0V, it can be used in a single cell.
