Mains Power Supplies in 12V, 24V and 48V Configurations

The AD Series units may be used to supply mobile radios and other appliances from AC mains used in offices, portable site cabins, communication cabins, telephone exchanges, remote antennae sites, ships, oil rigs etc.  The units will accept either European 230Vac or US 115Vac inputs and are available as standard in 12V, 24V and 48V dc output configurations. Input is via a standard IEC-320 C13/14 power cord with UK, European or US mains plugs – please state your requirement.

Rugged and Compact

These units, often referred to as ‘brick in the lead’ supplies are housed in a rugged, corrosion resistant anodized aluminium extrusion.  The low mass surface mount technology components offer excellent resistance to shock and vibration, thus further increasing the reliability of these products.  A green LED indicates when there is output from the converter.  This gives reassurance to the installation engineer and speeds fault finding.

Installation

There’s nothing worse than a power supply lying around on the floor.  The ‘T’ shaped mounting clip, common to many Alfatronix products, allows the power supplies to be installed quickly and simply in many out of the way locations, such as underneath desks or on walls.  The 3 point ‘T’ clip can be fitted securely, even on uneven surfaces , quickly and simply, then the power supply simply ‘clips’ in place

The ever popular ‘T’ shaped bracket allows the power supply to be fitted quickly and simply making for a fast and neat installation.

AD Series power supplies can also be fitted with DIN rail clips for rack mounted applications

Battery Charging Required?

A fixed voltage battery charging facility is also available with the supplementary loom; P/N AD BB loom.  For dedicated battery charging units, please check out our IC Series – Intelligent Battery Chargers  

Desktop Versions also available

While the brick power supplies offer a versatile solution, if you are powering a mobile radio, try our Desktop Versions.  These are configured to attach to the radio forming one dedicated unit and are available for a variety of radios including Motorola, Icom, Kenwood, Tait, Maxon and Vertex.

Alfatronix AD Series units are widely used throughout the world to provide reliable power supplies to radio repeaters for long range transmissions.

Full Circuit Protection

The AD Series supplies have transient, overload and overheat protection for reliable operation even in the Toughest environments
