1500KW Backup Power Supply Testing Load Bank
Introduction
AC480-1500kW composed of measurement & control part and load part, mainly including dry type AC load bank, auxiliary control data acquisition system, auto load/unload control system, cooling system etc.
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.
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.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.
