Notes:
1
) Batteries exceeding quoted maximum capacity can be used. However, full charging
and estimated battery charge level cannot be guaranteed.
2
) For ambient temperatures for up to +50 °C.
3
) Nominal value is 13.8 V @ 25°C. These voltages are electrically linked and are
controlled by the PS-x1 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
) In addition to polyfuse, the PS-11 module has a crowbar over-voltage and reverse
polarity protection. The battery input of the PS-21 module does not have auto-resetting
protection against reverse-polarity. Please ensure the battery is connected correctly.
5
) Negative: current flows from the battery (battery supplies power)
Positive: current flows to the battery (battery is charged).
