JUNXY-AC690V-1000KW-R Resistive AC Load Bank

New JUNXY-AC690V-1000KW-R Resistive AC Load Bank

Why need load bank testing

It is really critical that your standby power system say UPS(uninterrupted power supply), battery bank, generator, transformers, inverter etc working in good condition if switched to be loaded when the main power supply in maintenance procedure or stop abnormally. Downtime could be reduced by regular maintenance and thorough inspections which are the key to power supply systems maintenance.

 

Critical power backup equipment like UPS System and generator which especially located in harsh, dusty or corrosive environment will fail without proper preventative maintenance. JUNXY provides a whole range of custom preventative maintenance products solutions for UPS systems and generators and many more to ensure constant uptime for your power systems and make you prepared for anything.

 

Load banks help highlight a large range of faults on the equipment it tests. The first objective when testing with an electric bank is to ensure your equipment’s power supply is reliable. The underlying question that needs answering is whether your equipment will have sufficient power supply to ensure uninterrupted operational performance. The load bank also tests that the equipment is not faulty, that there are no faults in construction, that the aging of the equipment is in line with expectations, that the components are reliable and that there are no pending breakdowns or early signs of wear and tear. The load bank also ensures that the product delivers power conform to its specification.

 

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, which 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.Integrated AC & DC load bank could be made in one unit or separately with different load voltages as per your need for different applications.

 

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.
