High efficiency, open frame power supplies pack 100W in popular 5 x 3in footprint

A new family of 100-Watt open frame AC-DC power supplies from Ultimate Renaissance is available in the popular 5 x 3 inch (127 x 76.2 mm) form factor, delivering high power density for applications including data networking, telecom, computing, and professional audio/video equipment.

In addition to its small footprint, the CFM100 series also measures only 32.4mm in height, creating a very low profile solution with high power capabilities.

CFM100 single-output power supplies achieve 85% typical efficiency. Available outputs range from 5V to 48V, with ±1% voltage accuracy and line and load regulation ±0.5% and ±1% respectively. The universal AC input, from 90V – 264V (rms), makes CFM100 models suitable for virtually any market world-wide. Power factor correction is also integrated, saving external components and helping meet power factor regulations pending in local territories.

Protection features include auto-recovery over-voltage protection and continuous short circuit protection. Power failure protection includes 8ms output hold-up time, enabling the system to shut down safely.

All models meet CISPR/FCC Class B standards for conducted EMI, provide 4242Vdc input-to-output isolation, and leakage current less than 1.5mA.

The CFM100 is CE approved, UL listed and TÜV certified. It is designed and manufactured in facilities that carry international approvals including ISO 14001 and ISO 9001.
