Accessories for DMR radios and repeaters
The desktop power supplies, popularly called the "wedge" due to its distinctive, ergonomically friendly shape, offer a convenient way to convert 12Vdc mobile radio transceivers for use as desktop base stations.
They will operate from AC supplies, either 115V or 230V without manual adjustment and output up to 108W (9Amps).
BATTERY BACKUP BOX
The AD Desktop Power Supplies include a battery back up output as standard. This can be connected to maintain charge in a lead acid battery to supply power in the event of a mains failure.
A battery back up box is designed to fit underneath the desktop supply and radio assembly and includes a 7Ah lead acid gel battery, presenting all three components as one tidy desktop assembly.
The battery back up box also includes a speaker (mounted on the front of the unit) for those wishing to use hands free radio operation.
