Accessory F1
INTRODUCTION
The ACC-F1 power supply module is an accessory card that provides the UMAC backplane with system
operating power. The purpose of this accessory card is to allow a UMAC application to operate at a low
voltage of 24Vdc.
This power supply accessory has a 24Vdc input connector and an output connector that provides the
reg5Vdc and ±15Vdc that is also supplied to the backplane.
The ACC-F1 power supply also comes pre-configured for remote voltage sense on the 5Vdc bus: A
function that has been installed on the UMAC backplanes since their inception.
LEDs on the front panel indicate the presence of +5Vdc, +15Vdc, and –15Vdc.
