It provides users with high stability, high reliability, and a complete range of AC and DC power supplies.
Product Features:
1. The input of two AC power sources adopts the main and backup power supply methods, and the power input part has a manual direct supply function; 2. The input power circuit of the power system is equipped with overvoltage and undervoltage protection devices; 3. The 50Hz AC output branch power supply adopts centralized voltage regulation and isolated output mode to achieve; 4. The 25Hz power supply is implemented using a high-frequency switching power module, with a "1+1" hot standby working mode and split output; 5. The DC power supply is implemented using a high-frequency switching power supply, which can be divided into "1+1" or "M+N" redundant hot standby modes for output; 6. The 25Hz power module and the DC high-frequency switching power module are equipped with a freewheeling function to ensure uninterrupted output in the event of a fault transition between the two input power supplies; 7. The system adopts intelligent monitoring and is equipped with sound and light alarms; 8. The monitoring unit of the system achieves remote monitoring and centralized management through RS485 communication interface; Improve electromagnetic compatibility, lightning protection measures, and ensure high stability and reliability of the system in harsh environments.
