EPS emergency power supply, EPS power supply works, EPS emergency power supply manufacturers

EPS emergency power supply EPS emergency power, suggests that it is for the power to deal with emergency situations, it is in fact accurate EPS emergency power UPS is an uninterruptible power supply. By each switch device, automatic battery chargers, inverters and batteries and other components. The inverter does not work in the AC power grid is normal, after each vote an important device to load. When the AC power grid, the inter-switch device will immediately switching to the inverter power supply. When the grid voltage is restored, each switch device will be switching to AC power supply. Entire EPS emergency power system includes rectifier charger, battery, inverter, each switch device part EPS and EPS emergency power system controllers EPS emergency power supply works with single inverter technology, set charger, battery, inverters and control EPS emergency power unit in one. EPS emergency power back-up are generally used to run mode. 1, when the mains is normal, after each vote municipal electric system to supply the critical load, simultaneous detection of mains and battery charge management, and then to provide DC energy from the battery to the inverter. Here, the charger is a need only provide the equivalent of 10% of battery capacity (Ah) of the charging current of the DC power supply to the low-power battery, it does not have the ability to provide DC power directly to the inverter. At this point, the mains power to the load various emergency power supply system via a user bypass and EPS AC switch composed. At the same time, under the control of the logic control board EPS inverter stop working in automatic shutdown state. Under this condition, the power user load is actually used electricity from the grid, therefore, EPS emergency power supply is often said that has been working in the sleep state, you can effectively achieve the energy saving effect. 2, when the mains power supply is interrupted or overrun mains voltage (± 15% or ± 20% of rated input voltage), each switch device will be cast immediately cut power to the inverter, DC-energy battery support provided by the By this time, the power used by the user through the load inverter converts EPS AC power, not from the mains. 3, when the mains voltage returns to normal operation, EPS control center signals the automatic shutdown of the inverter, but also by its power from the inverter to AC bypass switch to perform power switching operation. Thereafter, EPS to the load in through the AC mains bypass path while also charging the battery pack through the charger. 4, except for the emergency lighting system, the frequency of which three-phase intelligent emergency power supply is mainly for a load of the motor to provide an emergency power system frequency, the product is easy to solve the emergency power supply and motor during startup impact of power supply equipment impact. Intelligent emergency power acceptable fire linkage signal, intelligent bus signal control building, and set priorities to prevent leapfrog control. EPS emergency power supply works EPS emergency power supply manufacturers EPS emergency power is accompanied by the generation of UPS uninterruptible power supply and the birth of the country's birth and UPS power supply in the late 1980s, while EPS power is born and the early 1990s, along with more than 20 years development, EPS power supply market has had a blue ocean market development to today's Red Sea Jedi, the price points continue to be sustained. EPS emergency power supply well-known manufacturers are: Shenzhen Renda group, Friends of the Shanghai Electric, Shenzhen's power within the industry are ringing technology manufacturers.
