20-120KVA Three Phase High Frequency Modular Online UPS

UM20-120kVA series modular UPS is different from traditional UPS in external structure. It can install all modules in standard cabinets, saving floor space and space, and facilitating installation, use and maintenance. In terms of design principles, the module UPS itself is a UPS, including rectifier, static bypass switch and attached control circuit. All power modules in the modular UPS system array bear the same system load, and each parallel module is an intelligent independent individual with built-in redundancy.  There is no need for the system controller to centrally control the parallel series. After any module fails (including the system control module), its redundancy design will give full play to its effectiveness, fully guarantee the normal operation of the equipment, achieve the greatest degree of fault redundancy, and the user can also choose redundancy with more than one fault tolerance rate as needed.  The availability of the N + X modular arr…
