RLC load bank control modes

Two control modes available for RLC load banks: The local panel control mode and the PC software remote control mode.

Local panel control mode available as below listed:

  • By contactor
  • By circuit breakerOr other switches as requested

PC software remote control (optional)

RLC load bank remote control communication protocol would be provided for clients’ integrating the load bank into the ATE system

Resistive, Inductive & Capacitive AC Load Bank (RLC)

RLC load banks are mostly used for inverter anti-islanding test experiments which meets the PV & grid inverter testing requirements for islanding prevention detection, work efficiency test, overload protection test, over-current protection test, power factor test, grid current harmonic test, resonance point test, and so on.

Both Leading power factor (Capacitive) and lagging power factor (Inductive) could be available with RLC AC load banks.
