MODULAR SMPS POWER PLANT

1. MODULAR SMPS POWER PLANT PUNCOM offersSMR-48V/33A , a switch mode rectifier module, designed to provide up to 33A of output current into a 48V nominal system for telecom, datacom, industrial and IT applications. It Converts 150-275V AC input power at 50 or 60 Hz 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 231A of current in N+1 configuration. Up to fifteen rectifiers can be configured in two 19” racks for a 462A ultimate capacity system in N+1 configuration using one control and supervisory unit (MiniCSU). 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 MiniCSU, making rectifier replacement a completely hands-off operation. The unit is fully hot pluggable. • Wide range of AC input, 150-275V provides protection from power disturbances and in combination with high interrupting capacity fast acting fuses translates into better reliability. • Battery temperature compensation • Compliant toIEC 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. SALIENT FEATURES • Hot Pluggable. • 231A in a 19” rack in N+1 configuration and 462A in two 19” racks in N+1 configuration. • Active power factor correction > 0.98. • 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.
