The wall-plug efficiency is the measure of output radiative-energy, in watts (joules per second), per total input electrical energy in watts. The output energy is usually measured in terms of absolute irradiance and the wall-plug efficiency is given as a percentage of the total input energy, with the inverse percentage representing the losses.
allowSmall – whether a small version of the message box can be produced with "small=yes". smallParam – a custom name for the small parameter. For example, if set to "left" you can produce a small message box using "small=left". smallClass – the class to use for small message boxes. substCheck – whether to perform a subst check or not.

This is a demonstration and test page for the code for the article message boxes. The boxes use one single meta template which in turn uses some CSS classes for pretty much all their looks. The meta template uses default images if no image parameter is given and it has some other nifty features.
the cooling output at full load in kW; the energy efficiency ratio in cooling mode at full load; the appliance type (cooling only, cooling/heating) the cooling mode (air- or water-cooled) the noise rating in dB (where applicable) Labels for air conditioners with heating capability also contain: the heat output at full load in kW; the heating ...
If energy output and input are expressed in the same units, efficiency is a dimensionless number. [1] Where it is not customary or convenient to represent input and output energy in the same units, efficiency-like quantities have units associated with them. For example, the heat rate of a fossil fuel power plant may be expressed in BTU per ...
The output impedance is a measure of the source's propensity to drop in voltage when the load draws current, the source network being the portion of the network that transmits and the load network being the portion of the network that consumes. Because of this the output impedance is sometimes referred to as the source impedance or internal ...
If the output is required to be isolated from the input, as is usually the case in mains power supplies, the inverted AC is used to drive the primary winding of a high-frequency transformer. This converts the voltage up or down to the required output level on its secondary winding. The output transformer in the block diagram serves this purpose.
