DIN-rail power supply units are stable in harsh automation environments

Recom expands its portfolio for industrial applications with a power range from 0.25 to 1000W and introducing two- and three-phase AC/DC DIN-rail power supply units. As the central power supply unit, the REDIN/3AC series is designed for “extraordinary” stability in harsh automation environments, says Recom. It will continue to operate reliably from mains voltages of 320 up to 575V AC even when one phase fails.

Recom is able to comply with customers’ requirements across the board, from low-power electronics and sensor technology with small and efficient DC/DC converters, to the central front end of a stable mains supply. The REDIN/3AC series delivers 120, 240, 480 or 960W at a stable 24V output voltage (trimmable from 22.5 to 29.5V DC) with only 40mV ripple. For power-hungry applications and redundancy purposes, the units can be connected in parallel with no need for additional components due to their built-in droop mode regulation, explains Recom and with current limitation to guarantee equal load distribution.

The power supplies are protected against overload with a power feedback function at over-temperature. The regulated power limitation also allows a stable start-up of non-linear loads.

These REDIN/3AC modules are certified to IEC/UL508 for industrial control equipment and EN/IEC/UL60950 for worldwide usage. They carry Recom’s five-year warranty. Samples are available from all authorised distributors.
