Embedded Switching Power Supply System - Customized Services
Detailed introduction
The HJDUM03 Series Embedded Switching Power Supply System, which Huijue Network designed, is in line with the demands of communication applications and energy-saving requirement. This series has a wide AC input voltage range, an extended operating temperature range, and features a high-performance embedded switching power supply. The system contains the HJDMA10-48/50 series of rectifier modules and the HJDKD03 monitoring unit. With its standard 19″ embedded installation, the integration is easily done. Distribution is provided on DC up to four user groups, split up in a way that can be set by the user. These groups may be metered and billed individually for power usage, RS485 or Ethernet monitoring interfaces, hence seamlessly managed.
