NOTES
1. The DTSPU25 Series is designated as DTSPU25x-y where x represents the type of AC input inlet connector, which can either be
A (IEC-320-C14), B (IEC-320-C8), or C (IEC-320-C6); y can be 102, 103, 104, 105, 106, 107, 108, 109, 110 or 111.
2. The output voltage is specified as a range (Ex: 40 ~ 48 VDC); the customer must specify what they would like the output voltage set at.
3. Models with output voltages under 30VDC 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).
