- Slides: 2
MODULAR SMPS POWER PLANT PUNCOM offers SMR-48 V/33 A , a switch mode rectifier module, designed to provide up to 33 A of output current into a 48 V nominal system for telecom, datacom, industrial and IT applications. It Converts 150 -275 V AC input power at 50 or 60 Hz into a highly regulated, filtered, low noise and isolated 48 V 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 231 A of current in N+1 configuration. Up to fifteen rectifiers can be configured in two 19” racks for a 462 A ultimate capacity system in N+1 configuration using one control and supervisory unit (Mini. CSU). The system can also be monitored and controlled remotely through modem or internet. 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 Mini. CSU, making rectifier replacement a completely hands-off operation. The unit is fully hot pluggable. SALIENT FEATURES Ø Hot Pluggable. Ø 231 A in a 19” rack in N+1 configuration and 462 A in two 19” racks in N+1 configuration. ØActive power factor correction > 0. 98. Ø Very High power density > 4. 0 W/inch 3.
