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.
