The DCSD-25 Series is designated as DCSD-25x-y where x can be A (9.2 ~ 18 VDC input voltage), B (19 ~ 36 VDC input voltage), or C (36 ~ 72 VDC input voltage) and y can be 5, 12, or 24 for output voltage. 2. All parameters are specified at rated input, rated load and 25C 70% RH. ambient. 3. Tolerance includes setup tolerance, line regulation, and load regulation. 4. Ripple & noise are measured at 20MHz using a 12" twisted pair terminated with a 0.1uF & 47uF capacitor. 5. Line regulation is measured from low line to high line at rated load. 6. Load regulation is measured from 0% to 100% rated load.
