Intervolt 24-12 VDC Voltage Converters Non-isolated Mini


The SVC Series utilises a common negative input/output design for maximum efficiency and cost effectiveness. If total galvanic isolation is required please see the SVCi Series product information.



interVOLT’s SVC Voltage Converters Non-isolated Mini Series are a condensed version of the tried and proven Maxi Series range packed with all the same features and benefits.

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

Designed for marine, automotive and industrial applications where an efficient, cost effective solution for 24VDC – 12VDC power conversion is required.


  • 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.
  • Conformity
    interVOLT converters comply with Australian and European standards for electro-magnetic compatibility (EMC), displaying both the ‘C’ Tick and ‘CE’ marks. These approvals are supported by independent examination from a certified testing house.
  • 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.

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.
