My understanding is that in a delta configuration the line voltage between any two phases is the same as the phase voltage in this case 240v.
Convert 3 phase heater to single phase.
At the heater there are 3 existing links across terminals 2 3 remove 2 of them.
You would need to buy a phase converter that can support the amperage and kw draw of the welding power source you are going to connect to it.
In a single phase ac power system there is only one single sinusoidal voltage.
Run two wires from the motor to the converter.
This device can be wired to the motor you plan to run that requires single phase power.
To convert 3 phase to single phase power you can use a phase converter.
Please don t do that when powering all three elements from a single phase you probably need to rewire the return circuit inside the heater.
I bought a 240v single phase space heater for heating up a warehouse space.
The warehouse has 240v power in a delta configuration no neutral.
This idea is not economic it would cost more to convert it safely than buying one or more single phase heaters either second hand or new to give the same heating effect 3 phase heaters are not.
The diagram and table below can be used to convert amperage between single phase and three phase equipment and vice versa.
About the 3 phase power source on single phase the answer is don t do it.
You will just need to know the amperage of the unit before ordering one of these converters.
But if you want an immediate solution then you will need to buy an single to three phase converter.
Then you just hook up the converter to the heaters and the other side of the converter to the single phase source and off you go.
Please inform your electrician that the way to convert your 3 phase devices from 3 phase to single phase is to.
