GFR1K5 power supply

XP Power unveils the GFR1K5 1500W AC/DC power supply series aimed at a broad range of industrial and communications applications that require bulk power within a compact 1U enclosure. The power supply series is available in four single-output models offering the nominal output voltages of +12-, +24-, + 48- or +56Vdc. The units can be mounted within a standard 1U height equipment rack. An optional rack mount enclosure is also available that allows up to four GFR1K5 units to be mounted side by side providing up to 6kW output. All units can be hot swapped and used in redundant configurations.

All voltage models have the same form factor and interconnection for applications that require more than one voltage rail, with the units being electrically polarized to prevent inserting in the wrong backplane position.

The mechanical design of the GFR1K5 includes a number of innovative design features, such as using only two internal PCBs, that aids the optimal flow of air through the unit, helping to maintain a low internal operating temperature ensuring long-term component reliability. The use of a dual stage power factor correction circuit and synchronous rectification techniques contribute to the unit's 90 percent+ power efficiency.

The +56Vdc output model suits PoE developments such as those required by networked security cameras, IP telephones and other network power installations requiring compliance with the IEEE802.3af PoE standard. For distributed power architecture (DPA) designs, typically required for DC/DC converters, the +48Vdc model is ideal. The +12VDC model is also suits DPA designs as well as for point of load applications.

The GFR1K5 can be used in current share designs where up to eight of the same output voltage models can share current within 10 percent of each other at full load. Another control feature includes the provision of an I?C compatible interface that can be used for monitoring output voltage and current, the unit's internal temperature as well as turning the output on/off.

A 5V/1A standby rail is standard. Other control lines and signals provide AC OK, DC OK, Inhibit, Enable and Fault indications. All models include international safety agency approvals to 60950 standards and Semi F47 compliance.

The GFR1K5 series is available from stock. The +12Vdc unit is priced at $390 in OEM quantities.
