W hy load bank testing is important?
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 wh ich 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.

he AC/DC load bank loading test preventa tive
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 whic h are the key to power supply
systems maintenance.

oad bank testing could help highlight a large range of faults on the power supply systems
it test. The first goal achieved when testing with FORESIGHT AC/DC load bank is to
ensure your power supply syst em is reliable or not by validating the power systems’
outputs to its technical specifications. The underlying question that FORESIGHT 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.
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 comprehens ively.
Integrated AC/DC load bank could be made in one unit or separately with different load

voltages as per your need for different applications.
