Power requirements
The AT110 operates from a DC Voltage between 5 and 50 Volts. We recommend that a
permanent power source is used to supply the AT110. If current drain is of concern, please refer
to the power management section for options to minimise vehicle battery drain when stationary
for long periods.
Fuse Recommendations
Typical current drain is 25mA @ 13.8VDC and 14mA @ 27.6VDC, although maximum peak
current can be around 500mA for very short periods. The AT110 is supplied with a 1.0m power
cable, which is fitted with 1A fuses in the power feeds and ignition sense wires.
Back-up Battery
The AT110 operates from the external voltage source, with an internal back-up battery to allow
continuous operation for short periods without external power. The device will maintain the
battery charge level and seamlessly switch to battery power if the external voltage source fails or
fall outside of the permitted range. Note that the operating temperature range of the AT110 is
reduced when the battery option is fitted (see Specifications section). Please also note the
handling precautions for lithium polymer batteries as outlined in the AT110 Installation Guide.
Powering up your AT110
Fitting the SIM acts as the on/off switch. Your AT110 will power up as soon as the SIM is
inserted.
LED Indicators
