6vdc @ 0.5A / 500ma 2.1mm plug
Polarity : center negative
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 cUL / us approved as well as CE and other approvals. The desk top units come complete with power cords
Brand name(s) : Mode Electronics

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.

These switching (solid state components, instead of a transformer) power supplies provide a regulated output voltage regardless of the current used.
