||℃<br>℃<br>a<br>1. All parametersNOT specially mentioned are measured at230VAC input, rated load and 25 _of ambient temperature.<br>2. Ripple & noise are measured at20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.<br>3. Tolerance: includes set up tolerance, line regulation and load regulation.<br>4. Derating may be needed under low input voltages. Please check the static characteristics for more details.<br>5. A-type only.<br>6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.<br>7. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the<br>complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.<br>8. The ambient temperature derating of 3.5<br>/1000m is needed for operating altitude greater than 2000m(6500ft).<br>9. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for<br>1 month.|||||||

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
