1MODULAR SMPS POWER PLANT PUNCOM offers SMR-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 V 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 systemparameters are automatically downloaded from the MiniCSU, making rectifier replacement a completely hands-off operation. The unit is fully hot pluggable.SALIENT FEATURESHot Pluggable.231A in a 19” rack in N+1 configuration and 462Ain two 19” racks in N+1 configuration.Wide range of AC input, Vprovides protection from powerdisturbances and in combination with highinterrupting capacity fast acting fusestranslates into better reliability.Battery temperature compensationCompliant to IEC & CISPR 22specs for EMI/EMC.Optional RS 232, RS 485,10Base Tethernet and modem interfaces.Fully menu driven with user friendlynavigator push buttons menu.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 anyadjustments.Digital active current sharing.Password protection againstunauthorized parameters change.
