Key Features

  • PROTECT VALUABLE ELECTRONIC EQUIPMENT - A small investment in a professional grade external power conditioner saves money, frustration and time

  • EXCELLENT LINE AND LOAD REGULATION - 20A continuous load rating. 93% efficiency. Highly stable under a range of input conditions (10/5 - 16 VDC)

  • SELECTABLE OUTPUT VOLTAGE (12 - 14.4V DC) - Galvanic isolation between input and output - Wide operating temperature (-25 to +50 C)

  • MARINE GRADE - Corrosion resistant materials; Conformally coated circuit board - Compact Size - Suitable for high/low temperature environments

  • STABILIZE VOLTAGE from alternators, generators, batteries, solar panels and unregulated DC power supplies in cars, trucks, RVs, boats, communications and industrial equipment


Dirty 12 volt DC power from vehicle, marine, solar, battery, generator or other direct DC power source can ruin expensive equipment. The interVOLT SPCi121220G2 is the perfect solution to ensure that your devices receive clean, stable power.

The SPCi121220G2 resolves power problems including voltage surges, transients, spikes, etc. It's a converter, stabilizer, isolator, regulator and battery charger all in a compact package.

The SPCi121220G2 is galvanically isolated (input to output) and designed to protect equipment connected to 12 VDC power sources. Its switchmode design is more energy efficient with less heat dissipation than cheap linear voltage regulators.

User selectable output voltage allows you to provide clean power to 12V devices.

Unique self diagnosing electronics provide valuable feedback. Illuminated LED icons display status, faults, load and other conditions.

Constructed of high quality, marine grade aluminum and ABS components. All hardware is non-ferrous and the terminals are plated brass.

Designed to operate in high ambient temperatures under constant load, the SPCi121220G2 delivers every time.

Innovative features. Rugged design. Simple installation. Peace-of-Mind.
