RLC load banks protections

Standard protections:

  • Emergency pause operation: one-key stop loading
  • Over temperature alarm/protection: alarm & remove load
  • Fan interlock protection: loading available after fan activated
  • Over voltage protection: alarm & remove load

Optional protections

  • Blower thermal overload protection: alarm & remove load
  • Short circuit protection by fuse (over current protection)
  • Phase sequence protection (for fans with 3phase voltage)
  • Or other functions as requested

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 

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.
