Hello there,

Can I use Hi-Link HLK-5M15 with 2 phase 230VAC for 1minutes max to identify misconnection? It will not be supplied 2 phase input indefinitely.

Thank you!

 

No. If you connect it between two of the three phases of a supply that is 230V AC phase-to-neutral, you get 400V. It won't like that.

 

If you are working on anything electrical you need some type of multimeter. If you are working on three phase supplies you need to understand three phase supplies. If you are in north America some people call the two live and neutral sytem 2 phase. It is realy single phase with the center tap of the distribution transformer connected to ground. this is the neutral wire. So you would measure 230 volts between the two live wires and you would measure 115 volts between neutral and either live wire. This means that if you are nominally at ground potential you would only get a 115 volt shock. With the european system live is about 230 volts with respect to ground so you would get a 230 volt shock.

I know how 3 phase supplies works. I know that is roughly 600VDC for the poor SMPS. I am asking this to someone who pushed it to the limits

At a guess it will have a 400V or 450v rated DC link capacitor. It won’t survive 563V, even briefly.

 

Certainly a direct connection across 600 volts, or even 300 volts, is quite likely to cause immediate damage and destruction of that supply module.
How is the supply voltage for this device provided in the actual application??
An actual isolation transformer with a 4 to one step-down ratio would allow testing within the allowed voltage limits. That could be a quite small transformer as there is no need to provide the specified inrush starting current. , but only the operating current.

Clarify your source, If this is 230vac 2-conductor, then it is single phase.
And you can use it for this application.
