Notes & safety
Notes: 1. Line regulation is measured from low line to high line at rated load.
2. Load regulation is measured from 0% to 100% of rated load for single output models.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uF & 47uF parallel capacitor.
4. This power supply is regarded as a component that will be installed into the final equipment. Final equipment must be re-confirmed that it still meets EMC directives.
5. This product is listed to applicable standards and requirements by UL
*Due to advances in technology, specifications subject to change without notice.
Safety Approvals: GB4943, UL60950, EN60950
