These extra small, efficient units are designed specifically for the industrial environment. Each unit is rated from ‑10°C to 70°C, with no derating necessary until after 60°C. Many extra "industrial" features are standard for the SDP. PowerBoost™ overload circuitry can start up industrial loads (i.e. motors, relays, solenoids and DC‑DC converters), that can cause ordinary power supplies to foldback or shutdown. Each unit contains a DC indicator and front panel adjustment potentiometer. With the Sola SDP series, you can count on a high grade design.
