Product Description


The RL Series Resistive Reactive Load Bank can simulate motor loads and electromagnetic devices within a power system as well as purely resistive loads by offering the ability to set a specific power factor (pf). Resistive Reactive Load Bank is the perfect solution for regularly scheduled maintenance testing and commissioning of mission-critical standby emergency power systems where rated kVA, rated power factor and rated current testing is required. Usually, it offers a 0.80 power factor load and is designed for testing large generators, switchgear, transformers and UPS systems.
Resistive Reactive Load Bank can be designed to install the resistive components and reactive components in one enclosure or two separate enclosure. Same as the Resistive Load Bank, it is available in stationary type for permanent installation or portable type with lifting rings, castors. Larger load banks, typically above 1250KVA, are based on an ISO container construction. Special finishes including custom paint colors and stainless steel casings can be supplied.
Main Features
1. Control mode: (1)local manual control panel (2)remote manual control box (3) remote console (include manual panel and PC control)(4)laptop control
2. Protection function: overvoltage, overcurrent, overheat, over low blowing rate, blower overheat, blower phase sequence reverse protection, smoke alarm etc.
3. Cooling: industrial heavy duty blower, horizon air intake, upwards outlet, low noise.
4. Power consumption components: made by special alloy resistance, high temperature resisting, high heat dissipation capability, high heat stability, no naked light, safety and reliability. Running temperature is 1/3 of rating.
5. Material and coating: the body adopt cold-rolled steel plate that processed by galvanizing corrosion protection, powder coated and spray paint.
6. Integrated & modularization design: easy to installation, maintenance and transportation.

Main 10 Technology Advantages

Kaixiang company is in leading position in generator set testing and maintenance industry, besides general functions, its load bank has following unique advantages:
1. Standard Testing Function: System can do stable test, transient test, and realize functions, such as setting, fluctuation, instant load, and instant unload.
2. Super Power Load: high load power density, large capacity of single set, parallel running to finish super power testing, and realize tens of megawatts of power loading.
3. Accurate Data: with high precision data collection module and measuring meter, related equipment has passed the certification by CMA (China Metrology Accreditation) qualification testing institution, and ensure the reliability of data.
4. Flexible Control Mode: based on different using habit, several control mode as following can be choosed, local panel operation, remote box controlling, and intelligent software. 
5. Intelligent Load: after setting generator rated power in software, system realize rapid loading through preset proportion, automatically and continuously load multiple power value and common tests, like stepping, full load, and over load, so that improve working efficiency.
6. High Efficiency Data Management: display real-time testing data, generate form, curve graph or report automatically, also can put data into storage. According to generator set No. set up testing file, support to query at any time, and improve data management efficiency.
7. Comprehensive Protection Function: multiple protection, like over temperature, smoke. When in danger, automatically terminate the test and give alarm to protect safety of personnel and equipment.
8. Stable Running: with the latest generation control module as the core, a sharp rise in system response speed and anti-interference performance, avoid function failure in complex electrical environment, and ensure system running stably and reliably. 
9. New Load Bank Technology: using the international advanced AC load bank technology, overcome the old water bank defects, such as bear bumpy, unable to use when go to sea, realize Mooring Trial and Sea Trail, and simulate the real working condition of generator running.  
10. Mature Manufacturing Technology: load element using excellent anti-corrosion materials, waterproof insulation container packaging, suitable for adverse environment such as ocean. Internal layout is reasonable, air channel is clear, rapid heat emission, and satisfy continuous working need.
