400V 550kW Automatic Portable Load Bank In High Performance and Grey Colour
Introduction
AC400-550kW Automatic Load Bank combine the dry type load module and automatic measurement and control module, it can accurately test output power and load capacity of all kinds of generators, offer scientific and high efficiency testing method for large power generator set.
The system is composed of measurement & control part and load part, mainly including dry type AC load bank, data acquisition system, auto load/unload control system, cooling system, auxiliary control etc.
Applications
Kaixiang load banks operate at the actual output voltage of medium voltage generators and therefore do not require large step-down transformers, which reduces the overall package size and installation costs. Kaixiang’s quality system is certified to meet ISO9001:2015 standards. Kaixiang AC load banks certified by CE certificate.
Kaixiang has more than 20 years of professional experience in testing and commissioning of generators, batteries and UPS. Our high capacity load banks are exported to more than 20 countries around the globe in a wide variety of applications such as military ships, offshore platforms, data centre, power stations, generator manufacturers and research institutes.Its customers widely distributed in America, Mexico, Netherlands, Australia, Singapore, Israel, Poland, Saudi Arabia, UAE, Egypt, Indonesia, Malaysia,Vietnam, The Philippines, Cambodia, Sudan etc.

Main features
(1) Load Testing: load power that not beyond the rated power, testing the output capacity of the generator set.
(2) Control Pattern: There is local control panel with several power steps; user can load/unload by button.
(3) Display Data: The local measurement meter can display voltage and current.
(4) Emergency Stop: user can load or unload with one key easy to control.
(5) Over Voltage Protection: When the load input voltage is over the safety threshold, it will auto unload and give a alarm.
(6) Short-circuit Protection: The load circuit equip with fuse, can avoid the risk of load short circuit or the current is over large.
(7) Overheat Protection: When the load temperature is over the safety threshold, it will unload automatically and give a alarm.
(8) Fan interlock protection: load bank cannot add any load when working power of fan is off.
(9) Protection Buttons: There are buttons for some protection, when misinformation occurs or user has special needs, user can temporarily turn off the corresponding protection function.
