SDP Series Power Supply Manual The SDP™ Series provides efficient power from 5 to 48 Vdc and up to 100 Watts in a choice of compact, lightweight DIN rail mounted units. These affordable power supplies offer the exceptional reliability and advanced features required for industrial use. They operate at temperatures ranging from –10°C/14°F to 70°C/158°F with no derating necessary until after 60°C /140°F. PowerBoost™ overload circuitry starts up industrial loads—such as motors, relays, solenoids and DC-DC converters—that can cause ordinary power supplies to foldback or shutdown. For ease of use, each unit contains a DC indicator and front panel voltage adjustment potentiometer.
