Power Supply Modules 1771P4S In good quality

Each ac input power supply generates a shutdown signal on the backplane whenever the ac line voltage drops below its lower voltage limit. It removes the shutdown signal when the line voltage comes back up to the lower voltage limit. This shutdown is necessary so that only valid data is stored in memory.

The external transformer rating (V A) of each power supply is greater than its real input power (W) because a capacitor-input ac/dc supply draws power only from the peak of the ac voltage wave form. If the transformer is too small, it clips the peak of the sine wave, when the voltage is still above the lower voltage limit. The power supply will sense this clipped wave form as low voltage and could prematurely shut down modules in the chassis.

The following Power Load and Transformer Sizing graphs display the backplane power load on the vertical axis. Since these supplies have multiple outputs, the backplane power load is given in watts.

• Use the real power value (W) for determining the amount of heat dissipation you will have inside the enclosure.

• Use the apparent power value (V A) for estimating power distribution sizing. 48 Publication 1785-SG001B-EN-P - June 2006

• Use the transformer load value (V A) of each power supply plus all other loads on a transformer to determine the required transformer size.
