The DTSPU20 Series is designated as DTSPU20x-y where x represents the type of AC input inlet connector which can either be A (IEC-320-C6) or B (IEC-320-C8); y can be 102, 103, 104, 105, 106, 107, 108, 109, 110 or 111 for output voltage. 2. 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. 3. To meet the total regulation specifications all models must use an AWG#18/4FT output cable. The regulation will change if the output cable is modified. 4. The PSE Mark is not for each model. Please contact sales if you need to put the PSE Mark on your products. 5. Optional output connectors are available (see “DC Output Plug Selector List” link located at the bottom of the “Desktop” category page). DERATING CURVE
