AC480V 45KW RLC Load Bank
Los bancos de carga JUNXY RLC se usan principalmente para experimentos de prueba antiinislamiento con inversor que cumplen con los requisitos de prueba de inversor fotovoltaico y de red para detección de prevención de isla, prueba de eficiencia de trabajo, prueba de protección contra sobrecarga, prueba de protección contra sobrecorriente, prueba de factor de potencia, prueba armónica de corriente de red , prueba de punto de resonancia, y así sucesivamente. Tanto el factor de potencia principal (capacitivo) como el factor de potencia de retraso (inductivo) podrían estar disponibles con los bancos de carga de CA RLC de la serie JUNXY.


Why need load bank testing

It is really critical to ensure that your 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.

 

Such power supply systems could fail without proper preventative maintenance. JUNXY provides a whole range of custom preventative maintenance products solutions for your UPS systems, generators and many more 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.

 

JUNXY AC load banks could help highlight a large range of faults on the power supply systems it test. The first goal achieved when testing with JUNXY AC 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 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 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 JUNXY series RLC AC load banks.
