What is the difference between the UPS power supply cabinet and the EPS power supply cabinet?
This depends on how you understand, the use of two products is not the same, the ultimate role is the same, the design is not the same.
EPS for fire, there will be switching time, UPS for more precise load without switching time,
The biggest difference is that UPS is 0 conversion time EPS conversion time is generally about 5 to 8 seconds
EPS is a UPS development direction, both are uninterrupted power supply, but in the scope of application and technical requirements on the difference is relatively large.
(1) the use of general EPS for the public safety power supply or emergency power supply; UPS for the daily computer, telephone or work-related equipment
(2) the output voltage requirements of different EPS requirements of the output voltage is not strict, the general output for the square wave, the voltage range is not very stable; and UPS output is mostly sine wave or approximate sine wave, the voltage floating range is relatively small.
(3) power factor and other parameters of the load with different load of EPS, and will bring a variety of linear and non-linear load, so the requirements are relatively high; and UPS PF is generally 0.8, the load nature is not very different.
(4) the priority of different work UPS general priority inverter filter output, and EPS as far as possible to take electricity.
