Extron PS 910 C (part number 70-774-01) — a 9 volt, 1 amp external supply with a captive screw output, now retired by Extron.

Nine volts is an unusual rail in AV, and when a legacy Extron device wants it there is no substituting a 12 V brick. The PS 910 C answers that specific need: 9 watts at 9 VDC, delivered through a captive screw connector whose ridged conductor is positive and smooth conductor is negative. The unit accepts any mains from 100 to 240 VAC, draws 11.2 watts at full load, and lives in the same eighth-rack 1U plastic shell as the rest of this family, so eight of them will sit across one rack shelf. Extron calculates MTBF at 1,000,000 hours.

Key Capabilities

• 9 VDC at 1 A, 9 watts, on a captive screw termination.
• Universal 100 to 240 VAC, 50-60 Hz input; 11.2 watts at full power.
• ZipClip 100 mounting clip included, Extron part number 101-002-01.
• Eighth-rack 1U case; up to eight units per Extron rack shelf.
• Calculated MTBF of 1,000,000 hours, energy efficiency level V.
• Convection cooled with no vents, in high impact plastic.

Where It Is Used

Service and replacement work on older Extron 9 volt endpoints in equipment racks, lecterns, podiums and desks. Extron notes this supply is not suitable for air handling spaces or wall cavities and should be secured in an ordinary location near the equipment it feeds.
