What are the input voltage margins and output adjustment limits for this DC-DC converter?

Input range spans -36VDC to -60VDC (nominal -48VDC). Output is regulated at +24VDC, adjustable between +20.5VDC and +29.0VDC with a continuous load capacity of 40A.

Is galvanic isolation maintained between input and output ports?

Yes, galvanic isolation of 1500VDC is provided between input, output, and chassis ground via high-frequency planar transformers and optocouplers, protecting 24V circuits from telecom bus surges.

How does the converter handle sustained output short circuits?

It employs constant-current limiting transitioning into auto-recovery hiccup mode under severe shorts, keeping thermal stress minimal and restoring normal +24V output immediately upon fault clearance.
