Product Description

High Efficiency 48V Sub-Rack Power System for Telecom Introduction SPS 48/2900 400A System is a compact and intelligent power system containing up to 8 SPS-48/2900 rectifiers, DKD41controller module, AC connection and DC connection. It supports remote monitoring and management with SNMP. 2*1U high rectifier shelf and 3U high control and distribution unit makes it easy installation and adds to the success of the system. Applications Fiber optic network Access network Transmission equipment Mobile communication Satellite communication ground station 2G, 3G base station Main Features 19'', 5U sub-rack, easy to be embedded into all Standard kinds of telecom equipment. System total capacity up to 23.2kw with 50A rectifier; RS232/RS485 and RJ45 communication interface, SNMP optional PFC technique features the system high efficiency, energy-saving and up to 0.99 power factor. Intelligent fan-cooling technique brings good cooling performance, low failure rate and high reliability. Fast on-line expansion of rectifier modules enabled by hot-swap. N+1 rectifier module redundancy Batteries monitoring and management enables backup batteries well maintained Technical Specifications AC Input Voltage: 85V--300V(Normal output between 176-300V) 1*three phase five wires input Frequency: 45 ~ 65Hz; Power Factor: = 0.99 Efficiency: = 94%, Rated; 95% maximum.
