The IAC-D cabinet was designed to provide step-down voltage transformation on the secondary side of the UPS and distribute power to critical loads from there. With standard K1 or K13 transformer options and flexbility for a single output or true distribution, the IAC-D offers a solution for everyone. Similar to the IAC-PD, customers who want true distribution may add panelboards, subfeed breakers, or mix and match to find the right combination to meet their needs.
