Medical industry requirements for high reliability, and load type complex, both information technology IT equipment, there are a large number of specialized medical equipment. Picture shows a typical health care system for the power supply solution. Dual mains and generator power after the switching system into the ATS to supply low voltage distribution system downstream. Installation of lightning protection system to ensure that the needs of mine. TVSS surge suppressors, and air conditioning equipment, power supply to the UPS system. For the health care system, and computer system is recommended to ensure greater reliability than stand-alone system, and availability. Icon UPS1 and UPS2 constitute a parallel system, UPS3 and UPS4 constitute a parallel system, between the two systems through the LBS (Load bus synchronization load bus synchronization) way to achieve real-time synchronization tracking to switch through the application of STS single-input system, an important way to ensure high reliability of the load. In addition, dual-input load, AC power distribution system through its dual power, dual power supply from a different UPS system. A large number of hospitals and other places for IT office equipment, recommended a separate UPS system, power supply, as shown in UPS5, this design ensures that the focus of medical equipment, IT equipment and a different power supply circuit, the load to improve their own security sex. For hospitals and other places, fire safety is critical, it is recommended to protect the EPS system. Lighting type EPS system can ensure fire emergency lighting, power-based EPS system can ensure the fire pump, elevator operation and other important facilities.
