Your message has been sent! We will contact you as soon as possible Monday - Friday 9 am to 5 pm (PST). In the meantime, we invite you to read our blog news.

REXGEAR RLC load bank testing solutions of predictive failure analysis for UPS(uninterrupted power supply), generator, transformers, PV system, inverter etc, to validate the condition and output of such power systems comprehensively. Integrated AC/DC load bank could be made in one unit or separately with different load voltages as per your need for different applications.

RLC load banks applications

  • Battery bank system
  • Energy storage system
  • Energy meter loop load test
  • Datacenter rack heat simulating
  • PV system Inverter anti-islanding test
  • Voltage regulator, rectifier aging load test
  • Genset, UPS load bank commission testing

RLC load banks loading elements (load bank types)

Alloy resistors, inductors & capacitors loading elements are combined used in RLC load bank as per clients’ need in different applications:

  • 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 (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.
