Input Specifications
General Specifications
Physical Specifications
Notes 1. All parameters NOT specially mentioned are measured at 24, 48, 96VDC input, rated load and 25 °C of ambient temperature. 2. Ripple and noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance: includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equpiment must be re-confirmed that it still meets EMC directives. 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. |
