These switching power supplies will accept input voltages of 90-240VAC 50/60Hz and will provide a constant output voltage (within approx. 10%) from no load to full rated current load. All are cULus approved as well as CE and other approvals. The desk top units come complete with power cords. The RoHS is 2011/65/EU.

Level VI efficiency (energy saving mode with no load = less than .1 watts) : Voltage output will be less than rated voltage, when nothing is attached to the adapter.
