Notes:
1
) Batteries exceeding quoted maximum capacity can be used. However, full charging
and estimated battery charge level cannot be guaranteed.
2
) Linearly de-rated to 45 W from +70 °C to +85 °C (de-rating factor is 1 W / °C above
+70 °C).
3
) Nominal value is 13.8 V @ 25°C. These voltages are electrically linked and are
controlled by the PS-x2 module when charging a battery. They will depend only on
backup battery voltage when RTU runs from the battery (e.g. when there is a Mains
outage).
4
) Linearly de-rated to 4.0 A from +60 °C to +85 °C (de-rating factor is 40 mA / °C above
+60 °C).
5
) Negative: current flows from the battery (battery supplies power)
Positive: current flows to the battery (battery is charged).
