Inverters
Inverters are an acceptable AC power source for the
Roughneck Electrofusion Processor
, though some
produce output waveforms that are troublesome with specific fittings. We recommend performing
compatibility tests using the lightest and heaviest anticipated loads before approving an inverter system. Feel
free to contact us to discuss issues regarding the use of inverters.
Sizing a Power Supply
JACKMAN FUSION EQUIPMENT does not recommend or endorse any particular type or brand of generator.
Power requirements vary depending on the fitting manufacturer, fitting size and ambient
temperature.
Every generator manufacturer determines the size of their generators differently. For example, a 5,000 watt
generator from one company may or may not be equivalent to a 5,000 watt generator from another company.
When determining the correct generator size, an operator must:
1.
Determine the maximum current required to fuse a particular fitting. This information can be obtained
from the fitting manufacturer.
Please note, the largest fitting does not necessarily require the most
current.
2.
Once the maximum fitting current has been established, divide this number by 1.90 to calculate the
amount of current required by the generator.
3.
After the current required by the generator has been obtained, multiply that number by 120 to obtain
the number of watts the generator will need to supply in order to successfully perform a fusion.
Example:
Maximum fitting current = 50 Amps
50.0 Amps ÷ 1.9 = 26.3 Amps required by the generator
26.3 Amps × 120 = 3156 Watts
In this example, to fuse a fitting requiring 50 amps, the operator needs a 3,200 watt generator capable of
supplying 26.3 amps continuously. Also note that the generator must be capable of supplying this amount of
current for sustained periods of time (10 or more minutes). Consult the
generator’s
manufacturer to make
sure that the output meets this requirement.
NOTE:
This is an oversimplified calculation. However, it is a good rule of thumb and will work in most cases. Please
contact our service department if you would like to discuss generator sizing issues in more detail (See page
15).
