~I.Brief Introductions

EKM is a new type of the three-incoming and three-outgoing modular UPS, which adopts the all-digital control technology, concentrates the most advanced technological results in the fields of the today's power electronics and the automatic control, thus making it the benchmark product in the UPS industry. The birth of the EKM has brought a new concept for the power supply scheme of the electrical equipment, which has further made a breakthrough improvement in the availability of electrical equipment. As a drawer structure and a highly intelligent modular design are adopted, it is provided with a function of easy pl ing in and pulling out, it meets the power needs and the reliability requirement through increasing or decreasing the modules in the cabinet and it allows online maintenance, when there is a module redundancy, so as to achieve zero downtime time for check and maintenance.
