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

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.

The 120/240V 50KW load bank is for split phase inverter load test, easy to use and over current/voltage protection

The load bank is designed for the AC120V & AC240V 2phase 3wires split phase inverter load test. Include the pure resistive, pure inductive and pure capacitive loading or combination loading. Power factor adjustable. 2 control modes: local panel by push buttons & PC software remote control

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.
