Hot swappable 1U 1500W AC/DC power supply suits bulk power and DPA applications

All voltage models have the same form factor and interconnection for applications that require more than one voltage rail, with the units being electrically polarised 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 (PFC) circuit and synchronous rectification techniques contribute to the units 90%+ power efficiency.

The +56 VDC output model suits Power over Ethernet (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 +48 VDC model is ideal. The +12 VDC model is also suits DPA designs as well as for point of load (POL) applications.

The GFR1K5 can be used utilised in current share designs where up to 8 of the same output voltage models can share current within 10% of each other at full load. Another control feature includes the provision of an I2C 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 5 Volt / 1 Amp 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 compliancy.

The GFR1K5 series is available from stock.
