Installation and design requirements of large UPS power supply

1. Requirements for large-scale UPS power supply on site and environment (1) The equipment installation site should be an “industrial type” hard cement-type horizontal floor. If an anti-static raised floor is used, it needs to be designed according to the weight of the UPS on the basis of considering the average load of the floor. Make

What is the difference between MPPT input and string input?

At present, different manufacturers have different technical routes for string inverters. There are unipolar and two-level inverters. The usual practice is to use a two-level electrical structure. The front stage is a boost booster, and the rear stage is a DC-AC inverter. Variable, the maximum power tracking MPPT is generally placed in the front stage.

Why is the active ingredient of the battery “lithium” What is the purpose of different formulations of positive electrode materials?

At present, most of the batteries of passenger pure electric vehicles have abandoned lithium iron phosphate, a cathode material, and switched to ternary lithium materials. The main reason is because of higher requirements for battery performance, that is, higher cruising range. Require. It has been more than two hundred years since the development of chemical batteries, and

What is ups used for?

Uninterruptible power supply is a system equipment that connects batteries (mostly lead-acid maintenance-free batteries) with the host, and converts DC power into city power through module circuits such as host inverters. There are large and mini UPS. Large ups are used in mining, aerospace, industry, communications, national defense, hospitals, computer business terminals, network servers, network equipment, data storage equipment,
