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.
