The ProEco line of power supplies is available in both single- and three-phase units that accept a range of ac/dc inputs. An auto-detect feature on each module makes switching between ranges unnecessary. Outputs with 12-, 24- or 48-Vdc are available for loads up to 40 A. A tri-colored LED provides local output status (indicating <90%/>90%/>100% load), and integral relay contacts provide remote status monitoring for easy detection and diagnosis of power issues. The power supplies feature efficiency levels of up to 93% and have an operating temperature range of –25 to 50 °C (70 °C with de-rating).
