News Release from: Murata Power Solutions
22/09/2008 The CF series from Murata Power Solutions is a new range of highdensity AC/DC switching power supplies. The single main output 200Wand 350W open frame units offer industry standard form factor andhigh density. They are ideal for use in distributed powerarchitecture applications, redundant (N+1) operations, informationtechnology equipment and industrial applications.
The series comprises a 200W model with a 12V (16.6A) main output,and a choice of three 350W models giving designers the choice of a12V (29A), 24V (14.5A) or a 48V (7.2A) main output. All powersupplies in the CF range offer a universal input (85 to 265VAC)with active power factor correction (PFC). They also feature anauxiliary 5V standby output to allow for system housekeeping andmonitoring.

The 200W CF200-A12C has a high power density of 8W/in.3 that helpsminimize the space required in customer applications. Synchronousrectification allows an efficiency level of over 80% to beachieved. Built to meet 1U height restrictions, the ruggedized openframe, U-channel package CF200-A12C has compact overall dimensionsof 127mm x 84mm x 39.6mm.

350W models (CF350-A12C, A24C and A48C) achieve a power density of9.5W/in3 and similar levels of efficiency to 200W variants. Overalldimensions of the 1U, open frame, U-channel package are 173mm x98mm x 36.6mm.

CF series switching power supplies utilise proven topology andcomponents to achieve high levels of reliability. They also featureactive load current sharing and include an OR-ing diode for N+1parallel operation. All models have a mean time before failure(MTBF) of 300,000 hours, are RoHS compliant and meet the SafetyAgency requirements of UL/CSA 60950-1 and the European, EN-60950-1standard.
