What is the difference between ups power supply and modular ups power supply?

rack-mounted UPS power supply inherits the achievements of traditional UPS technology in power device technology and manufacturing technology, but in system architecture, based on multi-module parallel connection, it not only realizes the hot plug of system modules, but also better handles the relationship of independent operation, mutual cooperation and smooth conversion of system modules. Compared with the traditional vertical (tower) UPS, rack-mounted UPS can be installed in standard cabinets, saving floor space, facilitating installation, use and maintenance, and using shorter power connection cables. Modular UPS can improve the availability of the whole system by reducing the failure points between key equipment and load. Renda energy rack UPS power supply has considerable advantages compared with tower UPS power supply. Its advantages mainly include the following three aspects: 1. Simple installation, convenient expansion and investment saving. 2. Rack UPS power supply enables the power supply system to respond to demand, so that the capacity can realize "dynamic growth" with the development of business, which not only meets the expansion needs of later business, but also reduces the initial purchase cost of users. 3 parallel redundancy, stable operation and high reliability.
