Product Description: Emerson r48-2900u power module is a high reliability, high power density, high performance, full digital communication power rectifier module designed by Emerson to meet the network requirements of 3g, fttx, data communication equipment, transmission equipment and access equipment. The maximum output current is 30A and the maximum output power is 2900w. Emerson 48V/30A communication power module has two models: R48-2900U, R48-3200e, in which R48-2900U is standard rectifier module, efficiency is 92%, R48-3200e is high-efficiency rectifier module, efficiency is 96%. Customers can choose different modules according to the actual situation. Emerson R48-2900U communication power module, nominal output voltage 48V, nominal output current 50A? For Emerson PS48600-3/2900, PS48300-3B/2900, PS48600-3B/2900 communication power system. It is suitable for Emerson ps48600-3/2900, ps48300-3b/2900, ps48600-3b/2900 communication power supply system. Product Feature: 1Input voltage wide range of power limit: power derating input voltage range: 85Vac ~ 176VA. 2.Do not work under static voltage: 415Vac. 3.Rated input current: <, 16A@2900W. 4.Double temperature limit power, over temperature protection. 5.Difference between DSP Software Current Sharing and Average Current <,+1.5A Module Internal Processor DSP Current Sharing Control-Average Current Mode-Constant Voltage Control-Module Autonomous Control-Module Failure Does not Affect Current Sharing-Uneven Current Alarm Yellow Indicator: Current Sharing Error exceeds 8A Red Indicator: No Output or Error exceeds 10A Can be Parallel Connected 48 no need to use the CAN bus to ensure the normal communication between all modules. 6.Overvoltage shutdown, automatic restart. 7.Hardware overvoltage protection. 8.Software overvoltage protection. 9.Input impulse current: <,30A 2, output limit power, short circuit current limiting. 10.Monitoring settings: 56-59V 11.There are two kinds of software overvoltage protection modes, which can be selected through background maintenance software. 12.Overvoltage lockup mode. 13.When the output reaches the software protection point, the module shuts down and maintains, requiring manual intervention to resume work, 14.Two overvoltage lock mode. 15.When the output reaches the software protection point and the output current is greater than 5A, the module restarts after 5 seconds of shutdown. If the second overvoltage occurs within the set time (default is 5 minutes, can be set), the module shuts down and maintains, requiring manual intervention before starting. 16.If the rectifier module output current is less than 5A (rated output 10%), the rectifier module does not turn off. 17. Artificial intervention: Reset the rectifier module by the monitoring module, or disconnect the rectifier module from the power system. 18. Slow start of current. Product Detail:
