 TOPIC -----------------------------------------------------------

 This article provides the electrical specifications for Apple peripherals,
 including printers, monitors, scanners, drives, modems, and so on. For
 information about other Apple hardware, see the Tech Info Library article,
 "Electrical Specifications: Apple Computers (1 of 2)".

 DISCUSSION ------------------------------------------------------

 The following Apple products are manufactured for use in the USA. In
 determining whether a particular product can be used internationally, there
 are three classes, depending on whether a product accepts a range in voltage,
 frequency or both (for more specific information, see the article, "Using
 U.S. Apple Equipment Internationally"):

 1) Universal
 ------------
 These products can be used internationally out of the box. Some of Apple's
 products are self-configuring devices or "universal" within a certain range.
 They can accept a range in both voltage and frequency, and only require a
 plug adapter for the specific locale.

 Example: The Quadra 800 accepts between 100-125 and 200-240 volts, 47-63 Hz.

 2) Frequency Independent
 ------------------------
 These products can be used internationally with a voltage transformer.
 Generally they are geared for U.S. 120 volt current, but are flexible as to
 the frequency they accept (for example, 47-63 Hz), and are known as
 "frequency independent." These products need a stepdown isolation transformer
 to adapt the voltage, and will handle the different frequency on their own.

 Example: The U.S. Performa 200 accepts 120 volts, 47-63 Hz.

 3) Frequency Dependent
 ----------------------
 These products generally cannot be used internationally. These are products
 that can work only within a narrow range in frequency; they are "frequency
 dependent." Transformers only transform voltage, so if the product requires a
 certain frequency, there's no practical way to convert both voltage and
 frequency.

 These products can ONLY be used internationally in countries with the same
 frequency as the country for which the product was manufactured. Further, a
 voltage transformer will be required if the destination country has a voltage
 different from the home country.

 Example: The U.S. Apple Color OneScanner accepts 108-132 volts, 58-62 Hz.

 NOTE:
 Computers with power outlets for peripherals do not condition the current as
 it passes through. So, for example, a monitor requiring 120v-60Hz current
 could not be used in a 220v-50Hz environment even if the computer from which
 it gets its power is able to accept the local current.

 The AC output of a Macintosh II is as follows: the monitor receptacle is
 rated for 3 amps steady state, 40 amps peak power. The power supply is fused
 for 6 amps to include the Macintosh II and monitor.

 The amperage on the back of the computer is what should be used to calculate
 load on a circuit. Typical circuits in businesses and houses are 15 Amps
 (some are 20, but rarer, and an electric dryer is usually 30, an electric
 range may have DUAL 30 Amp circuits wired together). With that capacity, you
 could have the following configuration (from the back of the CPU):

 CPU          5 Amps
 Monitor      3 Amps
 LaserWriter  7 Amps
 Total:      15 Amps

 Most of the time, the CPU will draw only 1-1.5 Amps, the Monitor about .5-1
 Amp, and the LaserWriter about 2 Amps. The difference is sometimes referred
 to as Nominal (high) versus Actual draw.

 These following values are accurate regardless of peripherals used with each
 device. For example, a Macintosh II with an EtherTalk NB Card, an 8-bit video
 card, and HD40 SC draws a maximum of 230 watts and 6 amps from the power
 outlet it is plugged into.

 Additional Information
 ----------------------
 "Current leakage" is the amount of current that is passed to earth ground.
 The current leakage of all Apple equipment meets the following specifications:

 - As specified by the UL standard for Apple equipment distributed in the
 United States, the current leakage will be less than 5.0 milliamperes.

 - As specified by the IEC 380 & 950 standards for Apple equipment distributed
 in France and most of Europe, the current leakage will be less than 3.5
 milliamperes.

  The PowerBook 500 series AC adapter has two separate outputs, VBatt and
 Vmain. The VBatt supply is used for charging the batteries while the VMain
 supply provides power for the PowerBook. Power from VBatt is automatically
 diverted to power the PowerBook if additional power is needed.

 * Amps calculated based on efficiency of power supply, except for Macintosh
 PowerBooks (amps calculated at 7.5 volts) and Macintosh Duos (amps calculated
 at 24 volts).

 ** The BTU calculation is Watts X 3.42 = BTU/hour.

 The BTU ratings for the Macintosh systems take into account any hard disk or
 expansion card(s) that may be installed internally.
