Notes
- Airflow of the A239B Power Supply is from the ejector to the power connector.
- Power Supply Efficiency affects the current draw in AC Watts from the
branch circuit. As efficiency increases, the current draw in AC Watts
decreases.
- To calculate maximum theoretical current draw in AC Watts, multiply the
maximum power supply output in DC Watts by the reciprocal of the power
supply efficiency.
- Theoretical values are typically higher than published values which are
based on measured outputs under controlled test conditions.
