Reliable, DIN rail mounted, switchmode power supplies from 1.25A to 40A dc

Wieland's new line of UL Listed and CSA Certified switching power supplies delivers a control voltage of 24 Vdc, at an output current from 1.25A to 40A.

Burgaw, N.C., February 1, 2010—Wieland's new family of UL Listed and CSA Certified switching power supplies delivers a control voltage of 24 Vdc, at an output current from 1.25A to 40A. Wieland offers nine models including six single-phase and three three-phase, approved worldwide for a temperature range from -25 degrees C to +71 degrees C. All models feature short circuit protection and a robust, proven design.

The six fully enclosed, single-phase units take minimum space on the DIN rail as their width varies from only 1.7 in. (43.5 mm) to 6.9 in. (175 mm). All single-phase models accept a wide universal input voltage range, allowing one unit to operate in many applications. Input voltage for three units range from 115/230 Vac and 210 – 375 Vdc, for two units from 85 – 264 Vac and 90 – 375 Vdc, and for one unit from 115/230 Vac and 120 – 370 Vdc. Output current varies from 1.25A to 20A dc.

The three fully enclosed, three-phase units measure only 3.5 in. (90 mm) to 10.9 in. (276 mm) wide. All three-phase models accept a wide universal input range, 400 – 500 Vac and 480 – 820 Vdc. Output current varies from 10A to 40A dc. Single-phase and three-phase units feature touch-proof screw terminations for input and output wire connections to ensure personnel safety.
