Notes & safety
Notes: 1. Ripple & noise is measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1µF & 47µF capacitors in parallel.
2. Tolerance includes set up tolerance, line regulation, and load regulation.
3. Derating may be needed under low input voltages. Please check the derating curve for more details.
4. The power supply is considered a component, which will be installed into final equipment. The final equipment must be
re-confirmed that it still meets EMC directives.
5. In parallel connection only one unit may operate if the total output load is less than 5% of the rated load.
Due to advances in technology, specifications subject to change without notice.
