Description

The HHD25 is a new series of high density H alfbrick size, H igh current, D ual output DC/DC converters with through-hole mounting. The products provide onboard conversion of standard Telecom and Datacom input voltages to two independently-regulated output voltages. Leading-edge technology provides extremely high efficiency and superior thermal performance which enables the products to deliver full rated power at 55°C ambient temperature with only 200 LFM forced air without addition of a heatsink. The outputs also track each other during both startup and shutdown.
