REP-F feedback electronic load
REP-F feedback electronic load
▲REP-F Series DC Feedback Electronic Load
The REP-F series DC feedback electronic load is a power supply developed for fuel cell stack and engine system testing. The power supply is based on the power frequency isolated IBGT two-pole conversion architecture power electronic converter. DC electronic load for high reliability, programmable, and automatic operation. With high precision and high dynamic response, the input DC energy full power segment can be fed back to the grid. It satisfies the low voltage and high current test and is used in test fields such as fuel cell stacks and fuel cell engine systems.
