Calculating Power Specifications
The Overall specification for power output in watts (or VARs) is based on the root sum square (rss) of the individual
specifications in percent for the selected voltage, current, and power factor or VARs parameters:

Because there are a tremendous number of combinations, you should calculate the actual power specification for your
selected voltages and currents. The method of calculation is best shown in the following examples (using 1-year
specifications):
Example 1 Output: 100 V, 1 A, 60 Hz, Power Factor = 1.0 (Φ=0), 1-year specifications
Voltage Specification Specification for 100 V at 60 Hz is 0.14 % + 18 mV, totaling:
100 V x 0.0014 = 140 mV added to 18 mV = 158 mV. Expressed in percent:
158 mV/100 V x 100 = 0.158 % (see “AC Voltage Specifications”).
Current Specification Specification for 1 A at 60 Hz is 0.10 % + 1200 μA, totaling:
1 A x 0.001 = 1000 μA added to 1200 μA = 2.2 mA. Expressed in percent:
2.2 mA/1 A x 100 = 0.22 % (see “AC Current Specifications”).
PF Adder Watts Adder for PF = 1 (Φ=0) at 60 Hz is 0 % (see “Phase Specifications”).

Example 2 Output: 100 V, 1 A, 50 Hz, Power Factor = 0.5 (Φ=60), 1-year specifications
Voltage Specification Specification for 100 V at 50 Hz is, 0.14 % + 18 mV, totaling:
