• Australian designed, engineered and manufactured
The SVC Series switchmode voltage converters from interVOLT
are used specifically to step-down the high 24VDC on-board
power supply to the lower 12VDC range. this is primarily because
12VDC is a more universally accepted voltage and there is a
greater range of accessories and equipment available on the
market. the SVC Series is ideal for operating a multitude of
12VDC items including but not restricted to, radio’s,
sounders, GPs, radar, sonar, instruments, stereo’s, laptop
computers, security systems, lighting, fridges, pumps and much
more. the SVC Series are non-isolated which means they utilise
a common negative between the input and output. Galvanically
isolated versions are also readily available and known as the
SVCi Series. In the majority of applications the non-isolated
version is preferred, generally because they are less expensive
tdan the isolated versions and because the higher specification
of the galvanically isolated model may not be required. |

DC-DC Converter "Isolated"
The SVCi Series switchmode voltage converters from interVOLT
are used specifically to step-down the high 24VDC on-board
power supply to the lower 12VDC range. this is primarily because
12VDC is a more universally accepted voltage and there is a
greater range of accessories and equipment available on the
market. the SVCi Series is ideal for operating a multitude
of 12Vdc items including but not restricted to, radio’s,
sounders, GPS, radar, sonar, instruments, stereo’s, laptop
computers, security systems, lighting, fridges, pumps and much
more. InterVOLT SVCi Series voltage converters utilise push-pull
technology and purpose designed circuitry to stabilize the
output voltage at a pre-determined setting. they are also galvanically
isolated which means the input circuit is completely electrically
isolated from the output circuit. interVOLT converters are
also available in a non-isolated (common negative) version
known as the SVC Series. In the bulk of applications the non-isolated
version is preferred, generally because they are less expensive
tdan the isolated versions and because the higher specification
of the galvanically isolated model is not required. |
