Compatible Ultra 4640 power adapter

This 12 V AC adapter replaces the PA-1120-42RU 3.0 supply for Ultra Premiere and Ultra 4K HDR streaming players. It accepts AC 100-240 V input at 50 or 60 Hz and delivers a regulated 12 V DC output. Built-in protection covers over-voltage, over-current, over-load, short-circuit and over-temperature conditions.

For Ultra 4620 4630 4640 4660 owners

The adapter fits Ultra Premiere 4620, 4620R, 4620RW, 4620X, 4620XB, 4630X, 4640 and 4660 models plus the 4611R and ADS-18FSR-12 12018EPCU2 units. It will not work with players outside this list, so buyers needing a different connector or voltage must choose another supply.

Output locked at 12 V DC

The single deciding specification is the fixed 12 V DC output; the unit auto-adjusts current but cannot change voltage. Verify that your device requires exactly 12 V before purchasing.

Questions about this item

How much heat or noise does the 12 V PA-1120-42RU 3.0 produce when powering a 4640 streamer continuously?

The adapter has no fan and runs silently; its multi-protect safety system includes over-temperature protection to limit heat during all-day use.

Which cable or connector must I already have to plug this 12 V adapter into my Ultra Premiere 4640?

The unit ships with a fixed DC output cord that fits the 4640 power jack; you only need a standard IEC C7 figure-8 mains lead for the AC 100-240 V input.

Will this 12 V supply safely replace the original brick on an older 4620 or 4630 player I still use?

Yes — the adapter is listed as compatible with 4620, 4620R, 4620RW, 4620X, 4620XB, 4630X and 4640 models, and its protection circuits cover over-voltage, over-current and short-circuit conditions.
