Product Introduction
Three phase EPS emergency power supply
[Overview]
EPS stands for Emergency Power Supply, which is an important component of modern building safety facilities. Generally, it is used as a power source for firefighting or production in emergency situations. For example, in high-rise buildings, shopping malls, hospitals, underground air defense projects and other places where there are many people, few exits, and limited natural light sources, once a fire occurs or the power grid is damaged, the light source disappears into darkness. At the same time, with many people and few exits, the consequences will be unimaginable. At the same time, the fire brigade may be unable to carry out rescue work due to a lack of power supply, which further exacerbates the severity of the disaster. If emergency power is available, it will greatly reduce losses, therefore emergency power plays an increasingly important role in ensuring the safety of modern society. The emergency power supply for fire lighting is based on the requirements of the fire protection regulations for civil and industrial buildings, and adopts a complete design circuit and advanced production technology. All technical indicators have reached relevant international standards. Emergency lighting is an important component of modern building safety facilities. During normal lighting, emergency lighting is crucial to ensure the safety and rapid evacuation of personnel and rescue work in special situations such as power outages, power outages, or fire related power outages. This product can be used for high-rise buildings, shopping malls, hospitals, underground air defense projects, etc.
Fire linkage interface, RS232 interface. Imported IPM intelligent power module assembly. Patent technology, low no-load current. American INTEL M80C196MC technology. PLC monitoring, LCD night crystal display. Isolate transformer output to reliably protect user equipment. The emergency output is pure sine wave AC power with low harmonic content.
