FST-380V/400V 1000KW Resistive AC Load Bank

Why load bank testing is important?

FST 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.


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 FST 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 FST 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.


FST 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
