NOTES
1. 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. Models DTSPU40-102 ~ DTSPU40-105 need to use “AWG#16, 4FT long” to meet CEC requirements and models
DTSPU40-106 ~ DTSPU40-111 need to use “AWG#18, 4FT long” to meet CEC requirements.
3. The regulation will change by modifying the output cable.
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.
