All control signals are with respect to Ground. Negative currents exit the power supply.
1 Signal goes low when any one of the three power supplies loses AC
2 Signal goes low when any one of the three power supplies fail
3 In a standalone shelf (without I2C control) Pull this pin to GND to turn on three power supplies at the same time. With I2C control, leave this signal ï¬oat and Use I2C to turn on one power supply at a time.
4 Recomended 10KOhm pull up resistor to host 3.3 or 5V rail
5 Short Sense+ to +Vout and Sens- to GND at the point of load
