This will be presented better in the future (is at the moment only a copy of this part of the handbook by John Kusching, swiftly copied - for a possible link object for this "complicated" field.

NOTE: On the model page, the word “Volt” is automatically entered at the end of this field! Therefore, do NOT enter “V” or “Volts” at the end of the voltage field!

This field has been expanded to 100 characters to allow more information (such as frequencies) to be added. Please use English for non-German speaking countries (Appropriate language of market-state is also acceptable). Here are acceptable inputs for the voltage field:

a) 
Simple Entry

- Specify voltage (and range if known) for DC power sources: 115 (or if range known 110 to 120)

- If the nominal voltage and range is known: 115 = 105 to 125

- Specify frequency and voltage (and ranges if known) for AC power sources: 60 cycles, 120 (or if ranges are known 50 to 60 cycles, 110 to 120). It is acceptable to use “Hz” in place of “cycles”.

- Specify voltage (and battery type if known) for battery power sources: 1.5 (or if battery type known “D” 1.5)

- Specify transformers when a single model number can have different transformers: Either transformer: 25 to 60 cycles, 110V or 50 to 60 cycles, 110V or 50 cycles, 220
NOTE: When there are different model numbers for models that have different transformers, separate models should be created.

b)
Specifying Ranges, Different Sources and Transformer Taps

- Old style of specifying range used dash character: 110-120 but prefer using new method: 110 to 120

- Use semicolon character to indicate different possible settings for a single voltage source: 110; 145; 200; 240

- For tapped transformers, specify number of taps: >2 taps: 110 to 120 (If number of taps unknown) or if number of taps known: 4 taps: 110, 145, 220, 240

- Some manufacturers (eg Philips) have transformers with tap ranges that join seamlessly together: 5 taps: 100 to 130, 130 to 160, 160 to 190, 190 to 220, 220 to 250

c)
Specifying Multiple Power Sources

- Use and character to specify multiple power sources: 2 & 90

- If known, take into account composition of power sources: 2 & 2 x 45

- If known, take into account battery types: “AA” 2 x 1.5 & 90 It is acceptable to add “V” after first voltage: “AA” 2V x 1.5 & 90 Use preferred codes for battery type: A, AA, AAA, C, D or Lantern (6V with spring connections on top).
See also Wikipedia for other battery definitions.
Also note the following (non-preferred) equivalences: AAA = UM 4, AA = UM 3, C = UM 2, D = UM 1

- Specify Bias Cell if known: 1.5V (Bias Cell) & AC: 60 cycles, 110 to 120

d)
Specifying Power Source Options

- Preferred method is to use “either” and “or” to specify power source options: Either AC: 60 cycles, 120V or DC: 12V or Batteries: “C” 2 x 1.5

- Old method used slash character to specify multiple power sources (not preferred): 60 cycles, 120/ 2 x 1.5

- Specify use of Adapter: Either AC Adapter: 60 cycles, 120V or Batteries: “D” 4 x 1.5
