In some cases, a customer desires to power some 120 volt equipment (like a monitor) along with a 208 single phase output to the main load. We can provide this capability as required. The KVA needs of the 120 volt circuit must be specified.
A variation of this is when two outputs are required, which may be the same voltage, but the neutrals must be isolated from each other. The necessary transformers and breakers can be included in our UPS or inverter, eliminating the cost of external transformers, breakers, and conduit between them.
