JUNXY-AC208V-100KW-R Resistive AC Load Bank
Regular AC load bank testing of generators provides an essential health check service to prevent diesel engine failure due to wet stacking. Wet stacking occurs due to under loading of the genset which results in wet un-burned fuel building up in the engine. Junxy Energy offers the AC load bank which could meet your demands.

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):

JUNXY load bank 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.

(1)Resistor material heat-resisting (max at 1300℃), performance stable, low temperature drift (5*10-5/℃) nickel-cadmium metal alloy (NiCr6023), advanced resistor technology.

(2)Tube is extensibility and antioxidant SS321 (1Cr18Ni9Ti), fill material is crystal magnesia powder(Sg-9), magnesia density at 3.0g/cm3±0.2, screw and fixed pillar are SS304 (0Cr18Ni9) . 

(3)Cooling fin height is7mm±2, thickness is 0.4mm±0.2 SS321 material, cooling fin interval ≤3mm±0.2.

(4)Single resistor voltage at DC3000V or AC1500V 50Hz, 1 minute will not be breakdown at 50Hz. Series resistors, withstand voltage will reach 20kV.

(5)At normal condition, cooling fin average temperature ≤300℃, maximum at 320℃, 5 times margin range to maximum1300℃, keep the resistor continue work.

(6)The resistor reach at 300℃ to 400℃, temperature drift≤±2%,resistive value will not much fluctuation under high temperature condition.

(7)Precision ≤ ±3%.

(8)Air outlet ≤ 80℃(1M).


JUNXY load bank control modes(remote control optional)

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.
