NOTES
1. For single output models the output voltage is specified as a range (Ex: 40 ~ 50VDC); the preset voltage will be set as
standard models if nothing different is requested. Please contact factory for ordering details.
2. The “
*
” symbol means PSE approval.
3. Models with output voltages under 15VDC have been approved by TUV/PSE.
4. Optional output connectors are available (see “DC Output Plug Selector List” link located at the bottom of the “Desktop”
category page). Please call factory for ordering details.
