AC415V-600KW-SOFTWARE-Copy.jpg Load bank applications:

JUNXY series pure resistive load bank is a safe and simple way to provide loading test, commissioning test, aging test, acceptance test for UPS, generator, AC voltage regulator, transformer, PV inverter, EV charger, AC & DC converter, battery bank, rectifier, energy storage system, PDU & many more AC & DC source. Such AC & DC source must be load bank commissioning verified before they could be used for the entire backup power system, make sure the backup power system runs perfectly in case of any downtime.

Load bank types:

The pure resistive load bank includes 2 load types regarding its load voltage types: pure resistive 1phase & 3phase AC load bank & pure resistive DC load bank. Vertical cooling load bank or horizontal cooling load bank, outdoor type load bank and indoor type load bank designed according to the test site condition.

Load bank functions & protections:

The pure resistive AC load bank outputs active load power only without the reactive power, The pure resistive AC load bank is capable to go by 3phase balance & unbalance loading test which meets clients’ different testing purpose. Load bank full power on/off is also a key function to test the power source on/off heavy load capability.

The pure resistive AC load bank digital meter testing each phase voltage, current, active power, power factor, reactive power & apparent power. The load bank load voltage & load current detected by the digital meter, and if the voltage & current exceed the preset value, the load bank digital meter will convert its NO contact to NC contact, activate the protection diagram, indicate over voltage/current alarm & protection with load removed automatically. A temperature sensor is also needed in case of load bank over temperature loading, to make sure the control system contactor, PLC, relay and its conducting wires always working in a good temperature condition.

It is very important to make sure fan always work normally to cool huge heat during loading test, so a digital meter to detect fan working voltage & current is needed. Alarm & load removed protection activated as soon as load bank fan low current and over voltage running.

Load bank fuse and circuit breaker protection is also essential for each load step, could provide the over current protection if any short circuit happens

Load bank control modes

The load bank has 2 control modes: either by local panel control or PC software remote control, 2 modes interlocked. The load bank communication by RS232, RS485, LAN, CAN. JUNXY series AC/DC load bank remote control communication protocol would be provided for clients’ integrating the load bank into the ATE system.
