Extron PS 1220 (part number 70-1259-01) — the eighth-rack, 2 amp member of the PS Series desktop power supply line.

Two amps at 12 volts, 24 watts in total, out of a case only 2.2 inches wide. That combination is what makes this the workhorse of the range: it drives Extron endpoints that outgrow a 1.5 A supply while still leaving room for eight units side by side across a single rack shelf. Standby draw is 0.04 watts, the lowest in the PS 12xx family, and Extron measures average efficiency at 91.11%. A ZipClip 100 bracket is included, and threaded inserts in the base let the unit bolt straight to an Extron rack shelf.
