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 series AC load bank testing offers you whole 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. Our solutions includes (click to view more):

About JUNXY load banks resistor
Highly reliable and durable new alloy resistor is used for the JUNXY's AC & DC load bank. It is thermal shrinkable and seal installed in the stainless steel pipe, whose surface with insulated heat sink. The resistor is moisture-proof, anti-corrosion, good heat dissipation, high insulation resistance, safe and reliable.
JUNXY load bank control modes
Two control modes available for JUNXY AC load banks: The local panel control mode and the remote control mode by PLC through PC software. Local control mode will be locked once load bank is switched to remote control mode. By applying the PLC, we could make load bank an intelligent test system, load power curve could be preset through PC software and all electrical parameters of EUT(equipment under test) including current, voltage, apparent power, active power, reactive power, power factor, frequency and warning info could be achieved automatically by the PC software and displayed by load bank digital meter. Up to 15 load banks at most could be parallel controlled by PC software which generating the test tables, curves and standard test report.

Note:
? Remote control function is optional
? AC & DC load voltage could be made compatible in ONLY one unit with several different load voltages.
? In some countries, 220V 1P will be replaced by 120V/230V/240V/277V 1P, 380V 3P will be replaced by 208V/400V/415V/480V 3P. Resistive AC load bank for load voltage 208V 3P and 120V 1P, 415V 3P and 240V 1P, 480V 3P and 277V 1P with higher load power are also available as per your need.
