Notes: 1. When adjusting the output voltage care should be taken never to exceed the stated output power or output current of the unit. 2. At full load, nominal input, 20 MHz bandwidth oscilloscope, tip & barrel method, output terminated with 10 uF electrolytic and 0.1 uF ceramic capacitors. Under light load conditions (<15%) the measurement may double in an effort to maximize converter efficiency. 3. At 230 Vac.

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.
