You could use two of the Delta low voltage DC units, and stagger the phases to get all three wires.

Hey all –

I have a customer [new] that has a Lorentz PS600 pump controller existing on a 48 VDC battery bank system for pressure pumping and she loses a controller a year to lightning.

There was no SOV or MOV on the 48 VDC input and I just ordered one to reinstall with the new controller. However I am looking for an MOV or SOV for the 3Phase15-45 VAC line to the pump as it leaves the controller to the pump.

Any suggestions?

Thanks in advance.
