Why load bank testing is important?

JUNXY series AC/DC load banks are for many power supplies load bank testing, to ensure that the standby power supply system say UPS(uninterrupted power supply), battery bank, generator, transformers, inverter etc which especially located in harsh, dusty or corrosive environment working in good condition, when you need them most, if switched to be loaded when the main power supply in maintenance procedure or stop abnormally.

The AC/DC load bank loading test preventative maintenance of such power supply systems could free you from power supply failure, to ensure constant uptime for your power systems and make you prepared for anything. Downtime could also be reduced by regular maintenance and thorough inspections which are the key to power supply systems maintenance.

Load bank testing could help highlight a large range of faults on the power supply systems it test. The first goal achieved when testing with JUNXY AC/DC load bank is to ensure your power supply system is reliable or not by validating the power systems’ outputs to its technical specifications. The underlying question that JUNXY series AC/DC load bank could answer you is--“how is my power supply systems constant uptime(technical performance) ?” The load bank also tests that the power supply system is not faulty, no faults in construction and components reliable, that the aging of the power supply system is in line with expectations and that there are no pending breakdowns or early signs of wear and tear.

JUNXY offers you whole AC/DC 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.

JUNXY series 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
  • Lack of air volume protection: alarm & remove load
  • Short circuit protection by fuse(over current protection)
  • Phase sequence protection(for fans with 3phase voltage)
  • Air inlet & outlet temperature monitoring
  • Or other functions as requested
JUNXY series load bank control modes

Two control modes available for JUNXY series AC/DC load banks: The local panel control mode and the PC software remote control mode.

Local panel control mode available as below listed:

  • By contactor
