OVERVIEW
The HC series is a family of highest performance open frame
DC/DC converters (OCA), based on the common and industry
compatible brick footprint. The converter meets the typical
telecom input voltage requirement of 36 to 75VDC, derating
might be required.
Other standard features of the high efficiency converter are out-
put voltages of 1.8VDC to 5VDC, short circuit and over voltage
protection, remote On-Off control, trim capabilities. The isolation
voltage spec is >1500VDC to meet the industry agency
approvals. Output ripple voltage is rated at 1% (or less) of the
nominal output voltage.
