How can you use 230/24 multiplus in a system that requires both 230V and 115v?

AC unit and another appliance requires 230 (US). But other appliances need 115v. The mains power going to the device will have to be 115V.

Hello, you would need 2 or 3 Multiplus units to make split fase or 3 fase system. Each Multi must be a 120 V model. Then you have 115 between fase and zero and 220 Between the fases.

best regards,

It's not possible to use 230V for both 230 and 115? Is the 230 dual phase like standard US 230? Can the 230v be stepped down to 115 with a step down unit of some kind. Just trying to find cheapest option.

Yes, like I mentioned earlier, an autotransformer will step down to 115V.
Make sure the ground relays are configiured correctly.
