HL6.AUG–Lambda–SC
Power factor correction for price of a conventional switching supply
Priced at just $475, the multioutput supply meets IEC 555-2 requirements
Until now, power factor correction has added anywhere from 10% to more
than 20% to the cost of a power supply. Lambda's PFC Series
multiple-output,power-factor-corrected power supply costs $475 in a 1,
000-W configuration. That makes it competitive with
non-power-factor-corrected supplies of equal power rating, says the
company. The supply meets the IEC 555-2 standard and is available with
three, four, or five outputs. Besides the 1,000-W version, the supply is
available in 300-, 500-, and 700-W versions. Output voltages are
combinations of 5, 12, 24, and 48 V, depending on the model. The input
voltage range is 85 to 264 Vac. Specifications for the supply include a
line regulation of 0.2%, load regulation of 1%, and temperature
coefficient of 0.03%/ degreesC. The operating temperature range is 0
degrees to 50 degreesC. The supply is protected from short circuits,
overvoltages, and overtemperatures, and is filtered to IEC 555-2 Class D
requirements. It complies with UL, CSA, and BABT requirements. (1,000-W
model, from $475 ea/prod qty–stock.) Lambda Electronics Inc. Melville,

CAPTION:
The PFC supply from Lambda, available in ratings to 1,000 W, has power
factor correction, but costs no more than a non-power-factor-corrected
supply.
