Notes

1. Ripple and Noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf & 47 uf parallel capacitor.

2. Tolerance: includes set up tolerance, line regulation and load regulation.

3. Mounting holes M1 and M2 should be grounded for EMI purposes.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted

Astrodyne products are not authorized or warranteed for use as critical components in life support systems, equipment used in hazardous environments, nuclear controls systems, or other mission-critical applications.
