Wieland UL Listed and CSA Certified (cULus) switching power supplies
With control voltage of 24 V dc and output current from 1.25 A to 40 A, Wieland offers nine models, single and three phase, temperature range from -25 °C to +71 °C.
Wieland’s new family of.
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 V ac and 210 – 375 V dc, for two units from 85 – 264 V ac and 90 – 375 V dc, and for one unit from 115/230 V ac and 120 – 370 V dc. Output current varies from 1.25 A to 20 A 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 V ac and 480 – 820 V dc. Output current varies from 10 A to 40 A dc. Single-phase and three-phase units feature touch-proof screw terminations for input and output wire connections to ensure personnel safety.
