Why need load bank testing ? Once your standby power supply systems say UPS(uninterrupted power supply), battery bank, generator, transformers, inverter etc are switched to be loaded when the main power supply in maintenance procedure or stop abnormally, it is really critical to ensure that they MUST be working in good condition when you need them most, especially for those located in harsh, dusty or corrosive environment.
Such stand by & inactive power supply systems could fail without proper preventative maintenance. JUNXY provides a whole range of custom preventative maintenance products solutions to ENSURE constant uptime for your power systems and make you prepared for anything. Downtime could also be reduced by regular preventative maintenance and thorough inspections which are the key to power supply systems maintenance.
What could be achieved by JUNXY AC load banks ? JUNXY AC load banks could help highlight the potential hidden faults of the power supply systems before they could cause a power disruption. The FIRST goal achieved when testing with JUNXY AC load bank is to ensure if your power supply system is reliable or not by validating the power systems’ outputs to its technical specifications, which is the MOST IMPORTANT question that JUNXY series AC load bank could answer you. A wide range of conditions that could threaten a power system could be detected by JUNXY load banks, say defective equipment, design errors, flawed construction, emissions, natural aging, improper settings on system control components and the negative effects of underutilization.
What products solutions does JUNXY provide ? 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): (1)Pure Resistive AC Load Bank(R) & (2)Rack Mounted AC/DC Load Bank
How is 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.
What are the JUNXY load bank control modes ? Two control modes available for JUNXY AC load banks: The local panel control mode by push buttons, mini circuit breakers and etc 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.
