Description

The HHS40 is a series of high-density Halfbrick size, High-current, Single-output DC/DC converters with

through-hole mounting. The products provide on-board conversion of standard Telecom and Datacom input

voltages to isolated, precisely regulated low output voltages. Very high efficiency and superior thermal

design enable the products to deliver full rated power at 55° C with 300 LFM or 45° C with 200LFM forced air

without addition of a heatsink. Such level of performance is presently not matched by other 40A rated

products on the market.
