Intervolt 12-12/24-24 VDC Power Conditioners Isolated Mini


The interVOLT’s SPCi Power Conditioners Isolated Maxi are known for resolving many of the issues associated with DC power in vehicles and vessels



interVOLT’s SPCi Power Conditioners Isolated Mini are condensed version of the tried and proven Maxi Series range packed with all the same features and benefits. They are in fact a converter, stabilizer, isolator and regulator all built into a single innovative package.

Like our SVCi converter range, these units feature galvanic isolation with no common connectivity between the input and the output whatsoever. This means peace-of-mind when connecting sensitive and often expensive, high-end electronic equipment to the output.


  • Diagnostics
    Unique to interVOLT, is the self diagnosing electronics. This design provides valuable feedback to installers and operators alike. An LED displays the system status and will indicate standby power, low input voltage, over temperature, overload and output short circuit.
  • Protection
    interVOLT converters feature a range of devices designed to protect the electronics from various connection and application problems. The units are protected against short circuit, overloading and excessive temperature. An internal fuse protects the electronics in the event of component failure.
  • Performance
    A key feature of the interVOLT mini series range is performance. Designed to operate in high ambient temperatures under constant load, the mini series delivers every time. Precise voltage regulation, superior noise filtering and excellent efficiency round off the performance package.

Housed in interVOLT’s new Mini Series enclosure which is not only stylish but compact, efficient and installer friendly.

About Intervolt

Since 1989, Amelec Australia has been a major importer and distributor of specialised electrical and electronic equipment, including Intervolt products, for the marine and automotive industries.

In the year 2000, Amelec recognized the need for high quality, marine grade, voltage converters to service the 24V - 12V DC power conversion market. Unable to source a suitable product from Australia or overseas, we embarked on an ambitious project to develop and produce our own range for the commercial marine market.  Our first interVOLT product, the Maxi SVC Series was born and introduced to the market in May 2001.

Since then, Amelec have introduced our acclaimed range of DC-DC Power Conditioners, Battery Equalisers, Voltage Stabilisers and Lighting Dimmers in both Maxi and Mini Series.

We are housed in our new R&D centre in Western Australia and continue with the design and development of exciting and innovative projects for the specialised DC market. With the new projects we have under development and our philosophy to maintain quality-at-value products we are confident of interVOLT becoming an international name in the power management and conversion market in the near future.
