Transformer Sizing

E 2011 Nordson Corporation
Review the following transformer sizing procedure to ensure that your
transformer is correctly sized for the number and type of hoses/guns you
intend to use.
To size your transformer
1. Determine the total power consumption (in watts) at 230 volts for all of
your hoses and guns. Table E‐1 lists the wattages of common hoses and
guns that are sold by Nordson Corporation. If your hose or gun is not
listed in Table E‐1, refer to the identification tag that is affixed to the
hose/gun.
2. Calculate the kVA rating of the required transformer by dividing the total
wattage calculated in step 1 by 1000.
Example
From Table E‐1, an application requires two 1.8 m Auto hoses at 155
watts each and two H‐402 (T‐LP) guns at 185 watts each.
The combined wattage of the selected hoses and guns is 680 watts.
680 B 1000 = 0.68 kVA
In this example, the 1.5 kVA transformer would be adequate.
