Description
HHS60 single-output DC/DC converters provide up to 60A output current in an industry-standard, half-brick
package. This high-density product converts standard telecom and datacom input voltages to regulated, low
output voltages. The HHS60's leading-edge technology provides high efficiency. Its thermal design enables
delivery of full-rated power at 55°C ambient temperature by using only 200 LFM of forced-air cooling without
the need of a heatsink.
