ELECTRONICS: Wieland’s new family of UL Listed and CSA Certified (cULus), switching power supplies delivers a control voltage of 24V dc, 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 to 71C. 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 inch (43.5 mm) to 6.9 inch (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 115/230V ac and 210 - 375V dc, for two units from 85 - 264V ac and 90 - 375V dc, and for one unit from 115/230V ac and 120 - 370V dc. Output current varies from 1.25 to 20A dc.
The three fully enclosed, three-phase units measure only 3.5 inch (90 mm) to 10.9 inch (276 mm) wide. All three-phase models accept a wide universal input range, 400 - 500V ac and 480 - 820V dc. 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.
