Wieland’s new family of UL listed and CSA certified (cULus) switching power supplies delivers a control voltage of 24vDC at an output current from 1.25A to 40A. There are nine models, including six single-phase and three 3-phase, approved for a temperature range from -25°C to +71°C. The six fully enclosed, single-phase units’ width varies from 1.7 in. to 6.9 in. (175 mm), and accept a wide input voltage range. The three fully enclosed, 3-phase units measure 3.5-in. to 10.9-in. wide, and all units in the family feature touch-proof screw terminations for I/O wire connections.
