1. 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 V 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
