As a central power supply unit, RECOM's REDIN/3AC series is designed for extraordinary stability in harsh automation environments while still continuing to operate reliably from mains voltages of 320 V_AC up to 575 V_AC, even when one phase fails. The REDIN/3AC series deliver 120 W, 240 W, 480 W, or 960 W at an output voltage of stable 24 V_DC with only 40 mV ripple, which is trimmable from 22.5 V_DC to 29.5 V_DC due to their precision potentiometer.

For power-hungry applications and redundancy purposes, the units can be connected in parallel with no need for additional components. Thus, a droop mode regulation with current limitation guarantees equal load distribution. These intrinsically-safe PSUs are protected against overload with a power feedback function at overtemperature. The regulated power limitation also allows a stable startup of non-linear loads. These modules are certified to IEC/UL508 Standard for Industrial Control Equipment and EN/IEC/UL60950 for worldwide usage and come with a 5-year warranty.
