Measurements

One can calculate the “Power Consumption” of a device, by reading the technical information on the manufacturer’s sticker on the unit.

Typically, a Watt or Ampere rating will be provided. The problem comes when we need to find out what the rating is in KW.

Power (Watts) = current (Amp) * Potential Difference (V)

For use in South Africa, the maximum rated Potential is 230 Volts (220 V)

If we looked at the back of a computer monitor, and we saw the rated AMP as 1.5A, How many Watts would this be?

Power (Watts) = current (Amp) * Potential Difference (V)

So Power = 1.5A * 230V

Power =  345 watts

So a continuous power supply of 345 Watts would be required to keep the monitor functioning.

There are various variables to consider when scoping out a generator for a business, and accurate onsite consultation will result in the correct business decision being made. There is no remorse like buyers remorse, being accurate creates no hidden expectations.
