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 output 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.
