| I、Introduction of EPS power supply
The EPS power supply is produced by the company for the need of the power supply equipment of first class such as fire protection facility, emergency lighting, and incident lighting. The product consists of interinput device, automatic charging machine, inversion power supply, and storage battery set. It supplies the important load through the interinput device when the AC supplying network is normal.
When the AC supplying network is broken down, the interinput device switches to the Inversion power supply immediately. The supply is switched from emergency power supply to supplying network when the latter resumes to normal. When the supply is off, the emergency power supply can supply to various electrical equipment. It has the properties of broad application, strong load suitability, easy installation, and high efficiency. The collective supply it adopts can overcome the disadvantages in other supply styles that cannot be overcome. It reduces the waste of unnecessary electrical energy. In places of emergency incident and lighting needed, its conversion efficiency is low and its performance price ratio is higher than that of the UPS power supply in continuous operation in a long time.
