telecom ups as a protective power equipment

UPS as a protective power equipment, computer ups power supply  it is important performance parameters should be considered when purchasing our focus. Mains wide input voltage range, it indicates that the ability to use mains strong (to reduce battery discharge). Output voltage, low frequency range, it indicates that the adjustment ability of the mains, the output is stable. Waveform distortion rate used to measure the stability of the output voltage waveform, and voltage stability is illustrated by zero when the UPS load is applied suddenly full load, emergency power ups output voltage stability.
Telecom ups as a protective power equipment from the basic application in principle, UPS is a storage device containing, as the main component in the inverter, power protection devices output voltage constant frequency. Mainly consists of several parts rectifiers, batteries, inverter and static switch and other components.

The practical application of telecom UPS

Telecom UPS is connected to one of each PV module inverter, telecom UPS and each component has a single maximum peak power tracking, so that the components fit better with the inverter. Telecom UPS typically used photovoltaic power stations, the overall efficiency of less than string inverters. Outdoor cabinet it is in the exchange at the parallel, which increases the complexity of the AC side of the connection, maintenance difficulties. Telecom UPS need to be resolved is how the other more effective and power grid, the simplest way is directly carried by an ordinary AC outlet and network, so that you can reduce installation costs and equipment, but often safety standards around the grid may allowed to do so, Telecom UPS may oppose power plant and the Pure sine wave ups is directly connected to an ordinary socket. Another relevant factor is whether you need to use and safety isolating transformer (high or low frequency), or allow the use of transformerless inverters.
