Industry-standard-footprint, pinout-compatible DC/DC converters from Lambda Electronics Inc., Melville, N.Y., aim at cutting 20% off the cost of competing units, with the PA providing about the same increase in output-current capability.
The half-brick PA series-a form, fit, and functional replacement for Lucent units-delivers from 50 to 150 W. Applications include telecom, switching equipment, and PCB-mounted power and distributed power.
Key features for the low-profile (0.5-in.) units include remote on/off control, 2:1 input-voltage range, agency-standards approval, and a two-year warranty.
A 150-W unit is $71 in 1,000s. Delivery is eight to 12 weeks in production quantities.
The PM series, also for telecom applications, delivers 10 to 30 W from a nominal 12-, 24-, or 48-V input (75-V input maximum with 2:1 input range). The wave-solderable, 0.35-in.-high converters, a second source for Artesyn converters, meet ETSI- standard ESI-300-132 requirements for inrush current and input surge voltage.
The converters come with a two-year warranty. The price for a 10-W converter in the PM line is $24 in amounts of 1,000. In production quantities, delivery time is six to eight weeks.
