Features
Intervolt's MAXI Series have long been the industry benchmark for high performance, premium quality voltage converters for the marine and transport industries. First released in 2001 and now used extensively throughout Australia and other countries, the interVOLT SVC series has now undergone a considerable transition and the next generation SVC is about to hit the market.
The GEN II Series is not just a cosmetic ‘makeover’ but rather a complete new product from the ground up. The all new design features complete digital control with a specification second-to-none. Here are just a few of the new features and benefits exclusive to the new range:Unique operator interface for control and monitoring (see detail below)

The operator interface panel is a unique and innovative introduction to the new generation SVC Maxi series. This component allows specific control functions to aid the installer/operator in addition to monitoring the status of the unit. The specific functions of the operator interface are as follows:
-
Selectable voltage output. The 24-12VDC version permits touch control selection of the voltage output from 12.0V to 14.0V in 0.5V increments.
-
A separate 2 stage battery charging function can be selected for automatic charging of an auxiliary 12V battery.
-
Output load indicator displays the percentage load (including overload) in a bar graph format for easy viewing.
-
Pre-emptive alarms for various fault conditions such as over load, over temperature, low input voltage and low output voltage (battery charging mode only).
-
Shutdown with alarm output for certain fault conditions such as overload, over temperature, low input voltage, fan failure and short circuit of output.
-
Reset of factory defaults
Specifications
Output Voltage (Converter Mode) - The voltage output is user selectable in 0.5V increments from 12.0V to 14.0V. The factory default is 13.0V which can be changed at any time.
Output Voltage (Charger Mode) - Two stage battery charging mode with boost voltage of 14.4V and float of 13.6V.
Constant Rating - All units are continuously rated at the published current at 40°C ambient temperature i.e. the 25Amp version is 25 Amps continuous.
Intermittent Rating - All units have up to a 25% rating over the continuous rating at a maximum of 50% duty cycle for 10 minutes.
Momentary Rating - All units peak at greater than 25% of continuous rating for a period of 10 seconds.
Input Voltage - Minimum start-up voltage is 20VDC but will allow input dip down to 17V during operation. Maximum input voltage is 33VDC.
Power Efficiency - Conversion efficiency varies depending upon load but minimum expected is 90% with a peak of 94%. Average is nominally 93%.
Standby Power - With no load connected (idle mode) average current draw is less than 25mA. With remote isolation enabled the average standby current is less than 10mA.
Output Ripple - Less than 20mV peak to peak.
Load Regulation - Less than 1% variation up to full load rating.
Line Regulation - Less than 1% variation subject to voltage input min/max specification.
Environmental Considerations - Operating temperature range is -25°C to + 50°C and ideally humidity should not exceed 90%.
Conformity - Conforms to Electro Magnetic Compatibility (EMC) standards as follows: IEC 61204-3 for low voltage power supplies, DC output, components EN61000-4-2 to EN61000-4-6 and AS/NZS CISPR 11 Group 1, Class B.
Construction - Manufactured using corrosion resistant materials throughout, including anodised 6063 aluminium, ABS/ PC plastics and stainless steel hardware. No ferrous materials are used and all PCB assemblies feature conformal coating (tropicalisation).
Safety Devices - Shutdown protection with automatic reset for input under voltage, output overload, output short circuit, over temperature and loss of negative reference using purpose built circuitry. All shutdown conditions are output to external source for remote monitoring. - Internal fuse protection (not user serviceable) for reverse polarity connection and output over voltage condition.
Alarm Devices - Pre-emptive warning for impending shutdown due to output overload, input under voltage and over temperature. All alarm conditions are output to external source for remote monitoring. - Failure warning of internal cooling fan due to obstruction, fault, damage, etc. Condition is output to external source for remote monitoring.
User Interface - the user or operator interface is used to control and monitor the various functions of the SVC. - Illuminated icons are used to display fault conditions for internal fan and temperature and various input/output conditions. - Status bar has dual use, to display operator selected voltage output in set-up mode and to indicate the percentage of load on the output in operation. On power up it will indicate the existing voltage setting for a period of 10 seconds.
Auxiliary Connections - for optional control and monitoring functions. - External Alarm Output - an external signal for remote monitoring of both the pre-emptive and shutdown alarms. - Minor Power Output - a permanent low current output used in conjunction with remote isolation i.e. to power a clock, etc. - Remote Switching Input - used to isolate the 24VDC from the 12VDC with a simple, low current, control switch i.e. toggle switch.
Termination - For input/output terminals the SVC uses high current proprietary terminals with combination M5 fasteners. The control/ monitoring terminal is a customised 3 gang Euro block. All in marine grade materials.
Warranty - 24 month end user warranty.

FAQs
Are the GEN II SVC Series converters designed for marine use?
Our G2 SVC Series converters are specifically engineered for marine applications and are not a redesigned automotive unit (see ‘Construction’ detail under specifications).
Are the GEN II SVC Series converters linear or switched-mode in design?
Our G2 SVC Series converters feature switched-mode technology in order to provide compact size and high efficiency, which cannot be obtained with conventional linear design (commonly known as voltage droppers).
Are the GEN II SVC Series converters isolated?
Our G2 SVC Series converters are electrically insulated from the case (ungrounded) as opposed to automotive style converters, which are grounded to the case. They are not however, galvanically isolated (DC-DC) as they use a common negative. Please use our SVCi Series if you require galvanic isolation.
Do the GEN II SVC Series have cooling fans?
Our G2 SVC Series converters are extremely efficient (typically 94%). Due to the high efficiency losses are considerably reduced, however there is always required to dissipate heat in some way. This can be achieved by either convective ( heatsinking) or assisted (fan) cooling or a combination of both. For the new G2 converters we chose a combination. It allows a more compact design as the amount of heatsinking can be reduced. Additionally the cooling fan is both speed and temperature controlled so it will only operate when required i.e. under large load or high ambient temperature.
Do the GEN II SVC Series converters run hot?
Because of the efficient design, the G2 SVC Series converters run considerably cooler than most comparative brands even in high ambient temperatures. The have been designed for use in high ambient temperatures such as those encountered in Australia.
