JUNXY Series Rack Mounted Load Banks 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. So validating the condition and output of such power systems must be conducted comprehensively. 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. Following on from construction and testing, Data Centre Commissioning is essential to ensure that the completed facility is configured for maximum efficiency. Missing out the essential Data Centre Commissioning can lead to an inefficient facility and higher than expected operational costs. By simply identifying where equipment manufacturers standard specifications are not appropriate for the IT load, the supporting infrastructure, in particular the cooling plant, can be configured to meet the requirements of the facility and lead to much higher levels of efficiency. Data centre commissioning can lead to significant energy savings when implemented correctly by a specialist commissioning team. By engaging JUNXY power solutions to ensure that systems are running correctly, clients have saved up to 67% on facility operational costs. The Junxy rack mounted AC & DC load banks are designed especially for internet data center (IDC) test and commissioning. Load bank integrated system test (IST) could precisely simulate the data center s electricity consumption, heat dissipation, air flow, hot & cold aisle testing, thus to ensure the effective operation of power supply & distribution system (generator, UPS, EPS included), air conditioning system, lightning protection and earthing system, monitoring system, data center integrated environments, cabinet IT environment, providing

independent verification of integrated system testing. Successful IST(integrated system test) should have installation of server load banks in data center and server room etc, Junxy provides resistive, reactive and capacitive load banks in low or medium voltage to cover the entire scope of your commission and testing requirements.

JUNXY Series Resistive AC Load Banks Purely resistive load bank is the most common type of load bank, and it proves equivalent loading of both generator and prime mover. That is, for each kilowatt of load applied to the generator by the load bank, an equal amount of electrical energy converts to heat by power resistors, in a general way, this heat must be dissipated from the load bank by air forced means or other convection. The Junxy's resistors are made by high quality finned tubular heating elements, they are of the type where the surface area is enlarged by a strip in order to heat gases. At high power the surface temperature is small and the heating element is short. Meanwhile, Load elements are cooled usually via Fan Forced Air, blower power is typically provided by an outside source. Selected load banks are available with blower power derived from the power source under test. Junxy's AC resistive load banks can be further divided into these categories: AC Small Portable: A resistive load bank easily carried or pushed on strong robust swivel wheels for testing and maintaining AC power equipment such as UPS systems and generators up to 150 KW. AC Large Portable: A resistive load bank on strong robust swivel wheels for testing and maintaining larger AC power equipment such as UPS systems and generators up to 1000 KW. AC Stationary: A resistive load bank for testing and maintaining AC power equipment such as UPS systems and generators at one location up to 4600 KW. Many models can be used as modular building blocks for applications requiring capacity of tens or hundreds of megawatts. Also the load banks can be loaded on a trailer for more flexibility. AC Medium/High Voltage: A resistive load bank for testing and maintaining larger generators and other AC power equipment up to 7000 KW and up to 15,000 volts

JUNXY resistive & reactive AC load banks are used to simulate the motor loads or other electromagnetic devices working at their rated power factor. For different testing purposes and applications, JUNXY mainly manufactures three kinds of resistive & reactive AC load banks: RL AC load bank, RLC AC load bank & RCD AC load bank. JUNXY Series Resistive & Inductive AC Load Banks JUNXY resistive & inductive AC load banks are used to simulate the motor loads or other Picture For Reference Only electromagnetic devices working at their rated power factor. Many backup generators and turbines are rated at 0.7, 0.8 or 0.85 power factor and need to be commissioned at nameplate capacity using a combination of resistive and reactive load to fully qualify their operating capability.

JUNXY Series Resistive, Capacitive & Diode AC Load Banks JUNXY series RCD load banks are similar to a reactive load bank in rating and purpose, except that leading power factor loads are created. JUNXY RCD AC load banks are used to simulate the no-linear or electronic loads typically for the industires: telecommunication, computer, UPS, generator & invertor. To test the real load capacity & crest factor. JUNXY series RCD AC load banks are used to test the REAL working condition of UPS, rectifier, inverter and etc who are loaded by non-linear or electronic load with non-constant resistance such as computer, networking equipments and etc. Through the accurate detection of its output and power quality, users could avoid the inadequate loading capacity or cause pollution to power grid, so as to guarantee supply security. JUNXY RCD load banks leading power factor loads are created to debug power supply system parameters such as its crest factor test. Development of digitization and networking with today's society, Rectifier loads such as computers, network equipment is widely used. These load with nonlinear characteristics of rectifier-filter circuits, its value is not constant, power output range, stability is even more demanding. UPS power supply, inverter power supply for network devices, you must use the simulated load is nonlinear, to debug parameters such as its crest factor test. But traditional RLC simulated load based on linear load, unable to change characteristics of nonlinear load simulation, also makes it difficult to test the UPS power supply, inverter power supply, such as in a data center, network tension power performance in your environment. Only RCD nonlinear loads, power supply output power and power quality make the most accurate judgment.
