- AppleColor High-Res RGB Monitor: Voltage Range Label Error
-
- Article Created: 28 February 1992
- Article Last Reviewed/Updated: 2 September 1993

- TOPIC -----------------------------------------------------------
-
- Later model 13-inch AppleColor High-Res RGB Monitors no longer designate on
- the back panel that they are compatible with voltages from 100 to 240. They
- show only 110-120 volts. Have there been any engineering changes to this
- monitor?
-
- If the monitor is being driven from the power output on the back of a
- Macintosh, will the correct voltage be delivered to the monitor even when the
- Macintosh is plugged into a European power source?
-
- DISCUSSION ------------------------------------------------------
-
- The current specification sheet states that the AppleColor Hi-Res RGB Monitor
- (model number M1297) supports a voltage range from 85 to 270 VAC, and a power
- frequency range of 47 to 63 Hz.
-
- There were some internal design changes in the revision B monitor, but the
- voltage and frequency range remained the same. Most of the changes were made
- to meet the Swedish guidelines for ELF emissions.
-
- The back panel identification was an oversight when the labels were printed,
- and the voltage range information was left off the label. Our engineers are
- aware of the problem and this should be rectified in future shipments of the
- monitor.
-
- In regard to the power out of the back of a Macintosh II, the power supply
- switches the power from the wall to the output plug. No voltage processing
- takes place. Any device that has the power plugged into the back of a
- Macintosh must meet the power requirements of that country.
