Product Introduction
Overview of Online EPS Emergency Power Supply
The online EPS emergency power supply can provide uninterrupted emergency power supply for the building's dual power automatic switching device, completely solving the problem that the dual power automatic switching device may suffer losses due to sudden power outages in one circuit and the inability of the circuit to achieve short-term self switching and self recovery, which may cause important equipment to malfunction.
Characteristics of online EPS emergency power supply:
The online EPS power supply has the advantages of soft start function, low starting current, stable starting speed, adjustable starting time, and no grid impact. There are two types of startup curves: 'S' curve and linear curve, which can be adjusted according to specific load types. The online EPS power supply has complete protection functions such as voltage stabilization, frequency stabilization, overcurrent, undervoltage, and output short circuit, and has strong overload capacity. Due to the continuous operation of the battery powered inverter, there is no issue with the switching time between the mains and inverter of ordinary EPS power supply, making it fully suitable for situations with strict requirements for power supply.
The online EPS power supply is designed and produced in accordance with the national standard GB16806-2006 "Fire Protection Linkage Control System", achieving zero time switching between mains power and battery inverter during power outages, completely solving the problem of normal operation of some lighting equipment, especially high-voltage sodium lamps, halogen lamps and other equipment. 1. Installation types: floor standing, split type, wall mounted, embedded. 2. Backup time: 90 minutes, national standard type, or customized according to the drawing requirements)
