SV 07 enableS mobile communication
The Supply Unit SV 07 provides electrical power for communication
equipment with 24VDC nominal voltage. It is optimized for operation of
sensitive radio receivers and gets supplied by different sources such as AC
mains, generator or vehicle power. An additional system battery covers peak
demands and supplies uninterrupted power. Internal control circuits protect
the equipment. An integrated display informs the local user of relevant data
such as source voltage or load current. The Supply Unit SV 07 offers five
different protected connections and allows for parallel operation in order
to increase the available power.

FunctionS
The Ascom Supply Unit SV 07 supports the following modes of operation:
Mobile Operation
If the vehicle motor is running the loads are fed from the vehicle alternator
via the SV 07. At the same time the system battery is charged via the SV 07. If
the vehicle motor is not running, the flow of energy is inverted: vehicle battery
and system battery supply the SV 07 and the connected loads. The protection
circuit of the SV 07 avoids a total discharge of the vehicle battery.
Stationary Operation
The SV 07 is supplied by a 230VAC source such as AC mains or a generator
and – if existing – is supported by the system battery. The system battery is
charged and the other loads are fed via SV 07.
Charging of Vehicle Battery
If the vehicle battery is connected to 9 [System Accu] the vehicle
battery is charged. Charging current is automatically limited to 20A max.
Housing, Cooling, Ventilation
The Supply Unit SV 07 is available in a 19’’ housing. It is intended for use in
a wheeled vehicle. The housing is made of aluminium and complies with IP55.
Internal cooling is realised using a passive cooling system. If required, ex-
ternal ventilation of the cooling element can be achieved through an optional
external fan. Operation of the external fan is controlled by SV 07.
Cables connected to SV 07 do not require shielding.
