Product overview:
Our company adopts the world advanced resonant voltage type double loop controlled resonant switching power supply technology. Because of its high reliability, small volume, light weight, superior technical index, modular design, N + 1 hot backup mode, easy control and other advantages, our company has been widely used in many fields, such as computer, aerospace, instruments, electric power Force, communication and other aspects are widely used.
As EPS power system is widely used in various buildings and public places, the reliability of equipment is very important because it provides power for various emergency power equipment at critical times. EPS charger is an important part of it. The reliability of charger directly affects the overall reliability of the system, so the reliability of charger is very important. In view of the performance requirements of EPS system, th series resonant soft switch fire power supply module developed by our company is a new type of high frequency switch power supply specially developed for fire protection system. It has the advantages of small volume, light weight, high efficiency, high reliability and easy operation. It is equipped with standard RS-485 interface, which is easy to connect with automation system. Suitable for fire protection and related industries.
Product features:
High reliability, stable performance and small interference.
High efficiency, module efficiency can reach 92% - 96%, can be cooled by air convection.
Independent current sharing with isolation is adopted, and the uneven current degree of parallel operation is less than ± 5%. When the parallel machine is used, the single module fails and automatically exits the system.
All kinds of protection and alarm functions are perfect, which can be displayed by alarm light and fault code, and sent out by communication and fault node signals.
The module has built-in DC output isolation diode (users do not need peripherals) to improve system reliability.
The module is led nixie tube display, with display switch button, manual voltage regulating button and dial switch, which is simple and practical.
The three-phase input module adopts "three-phase passive power factor correction circuit", without neutral line design, and the power factor can reach 0.94.
Light weight, small volume, saving installation space.
