As a central power supply unit, RECOM's REDIN/3AC series are designed for 2- and 3-phase operation, providing exceptional stability in harsh automation environments while still continuing to operate reliably from mains voltages of 320VAC up to 575VAC, even when one phase fails. Due to their precision potentiometer, the REDIN/3AC series maintains constant power levels at a stable 24VDC with an output trim range of 22.5VDC to 29.5VDC.
