Global Power Input Requirements Know the Market your product is Intended to Serve ! Min Voltage Variation = Nominal +10%/-15% Min Global Voltage Range: 85 – 264 VAC Note: Many products relax to 100 – 240VAC Min Frequency Variation = Nominal +/- 3 Hz Min Global Frequency Range: 47-53Hz, 57-63 Hz Note: Many products use 47-63 Hz Plug versions to cover Types A-M For complete global listing see World Wide Electricity Reference document

COUNTRY VOLTAGE FREQUENCY PLUG COMMENTS Afghanistan 220V 50 Hz C & F * * A UN correspondent reports C and F common in Kabul, but its likely a variety of plugs may be used around the country.  Some sources report Type D also in use. Albania 220V* 50 Hz C & F *Voltage variations common Algeria 230V 50 Hz C* & F *A variation of Type C with a ground post offset about 1/2-inch from center may also be found. American Samoa 120V 60 Hz A, B, F & I   Angola 220V 50 Hz C   Anguilla 110V 60Hz A (maybe B)   Antigua 230V* 60 Hz A & B *Airport area is reportedly Antigua power is 110V.

Military Power Quality Stds MIL-STD-1399: "Interface Standard for Shipboard Systems" covers the design and testing of electric power systems and user equipment. It applies only to shipboard power. The standard is fairly complete, covering Type I, II, and III shipboard power. It provides specifications on sags, interruptions, impulses, unbalance, and harmonics. Last revision: Notice 1, 11 Mar 1992. MIL-STD-704E: "INTERFACE STANDARD: AIRCRAFT ELECTRIC POWER CHARACTERISTICS" specifications for aircraft power quality, including DC, single-phase, and three-phase systems. It provides specifications on sags, interruptions, impulses, unbalance, and harmonics. Last revision: 1 May 1991. MIL-M-24116B(SH): "Monitors, Voltage and Frequency, 400 Hz Electric Power" covers trip levels and durations of voltage and frequency monitors. It applies only to shipboard installations.
