Alfatronix AD MT-3100/DM is a desktop power supply that turns a Motorola mobile radio (including MOTOTRBO DM4400/DM4600, DM3400/DM3600 and TETRA MTM5400/MTM800) into a base station. The radio mounts directly on the power supply, and the whole set sits on a desk and runs from a 115 V or 230 V AC mains socket – the input voltage is selected automatically, with no switching. The power supply has a characteristic "wedge" shape that tilts the radio's front panel slightly towards the operator.
The 13.6 V DC output rated at 108 W (9 A) powers the radio at full transmit power, and the battery output lets you connect backup power: the power supply keeps the battery charged and switches over to it when mains power fails. A solution for dispatch rooms, fire stations, gatehouses, site offices and crisis management centres, where communication has to work during a power outage as well.
