SMPS POWER PLANT SMR 48V/25A SALIENT FEATURES PUNCOM offers SMR-48V/25A , a switch mode rectifier module, designed to provide up to 25A of output current to a 48V nominal system for telecom, datacom, industrial and IT applications. It converts 90-300V AC input power at 50 or 60Hz into a highly regulated, filtered, low noise and isolated 48V DC output. The unit is designed for N+1 redundant configurations. Up to eight rectifier modules can fit in a single 19” rack to provide 200A of current in N configuration and 175A of current in N+1 configuration. One control and supervisory unit (MiniCSU) is used for configuring the system. The system can also be monitored and controlled remotely through Remote Monitoring Unit. The rectifier has been designed with a “plug-and-play” feature i.e. when a rectifier module is plugged into a live system the relevant system parameters are automatically downloaded from the MiniCSU, making rectifier replacement a completely hands-off operation. The unit is fully hot pluggable. There is provision of monitoring key parameters of battery for checking the health of battery using Battery Health Check Module. Parameters like cell temperature, cell voltage, cell conductance etc can be measured. SMPS Power Plant is type approved to TSEC & RDSO specifications SALIENT FEATURES Hot Pluggable. 200A in a 19” rack in N configuration and 175A in N+1 configuration Wide range of AC input, 90-300V provides protection from power disturbances and in combination with high interrupting capacity fast acting fuses translates into better reliability Battery temperature compensation Compliant to IEC 61000 & CISPR 22 specs for EMI/EMC Optional RS 232,RS 485,10Base T Ethernet and modem interfaces Fully menu driven with user friendly navigator push buttons menu Type approved to TSEC & RDSO Specs Active power factor correction > 0.95. Very High power density > 4.0W/Inch3. High efficiency: better than 90% at > 50% load. Plug and play capability without any adjustments. Digital active current sharing Password protection against unauthorized parameters change
