Division Equation 6 Calculation of Maximum On Mode Power (PON_MAX) in Watts for Signage Displays

United Kingdom

Original text. Later amendments are not shown.

PON_MAX = (4,0 × 10– 5 ×  × A) + 119 × tanh(0,0008 × (A – 200,0) + 0,11) + 6

Where:

  • PON_MAX is the Maximum On Mode Power, in watts,

  • A is the Screen Area in square inches,

  •  is the Maximum Measured Luminance of the Display in candelas per square metre, as measured in Section 6.2 of the test method,

  • tanh is the hyperbolic tangent function, and

  • the result shall be rounded to the nearest tenth of a watt for reporting.
