SV 07 enableS mobile communication

The Ascom Supply Unit SV 07 enables the

uninterruptable and emission free supply of

communication equipment in vehicles, remote

stations and containers.

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.
