NOTES: 1) All logic outputs listed below feature a standard active pull-down output with 0.4V max at 40 mA sink capability, and a 100k pull-up to 5V.

2) In addition to those listed below, signals and front-panel LEDs are provided to indicate: overtemperature/fan fault, AC phase

imbalance, output good, interlock open, and supply inhibited. The FXP also provides 4 LED’s indicating output loading.

3) Both signals must be pulled to logic ground for the unit to operate. Enables are 100% redundant internally for applications where redundant inhibit is desirable.
