Lambda Launches Space Saving AC input Power Modules Capable of Operating at High Temperatures

SAN DIEGO, CA (November 6, 2006) - Lambda has launched a series of AC input power supply modules capable of operating up to 100deg;C base plate temperatures. The innovative PFE series allows designers to utilize a single device containing power factor correction, regulation and primary secondary isolation, offering up to 50% space savings over previous products. These modules meet the needs of many industrial, datacom and telecom applications particularly where high operating temperatures are required.

The fully regulated PFE 500-watt models are available in 12, 28 and 48–volt nominal outputs and can be adjusted over a ±20% range. The 12-volt PFE500 delivers 396-watts with a maximum base-plate temperature of 85 oC, while the 28 and 48-volt models provide 504-watts at 100°C base plate temperatures. Line and load regulation is 0.4%.

The semi-regulated PFE700-48 can deliver 714-watts with a nominal output of 51-volts and can be operated as an intermediate bus converter powering regulated DC-DC converters for multiple output applications. Maximum base-plate temperature is 100°C, derating linearly to 85% load above 85°C. Line and load regulation for the PFE700-48 is 4-volts.

The PFE series accept a wide AC input from 85 to 265VAC, have active power factor correction and an input to output isolation of 3000-volts AC. All models have over-voltage, over-current and over-temperature protection.

The PFE size comes in a compact 4.6- x 2.4- x 0.5-inch package and can be cooled utilizing a cold-plate or an optional heat-sink.

The new Lambda power supply is safety-approved to UL60950-1, CSA60950-1 (C-UL) and EN60950-1. All units are RoHS-compliant and carry the CE mark.

The PFE series is available now, priced at $185 each in 100-unit quantities. More information can be found at Lambda's Web site,
