Intervolt Maxi Power Conditioner 12V 24V DC Marine Isolator

Intervolt SPCi121220G2 Maxi Power Conditioner redefines how you power sensitive equipment aboard by pairing a DC-DC converter, a stabilizer, an isolator and a regulator in a single, compact unit. Part of the InterVOLT SPCi Maxi Series, it tackles the challenges of onboard 12VDC and 24VDC power with precision and reliability.

Why this Maxi power conditioner stands out

• galvanic isolation between input and output: no common connectivity means clean separation of grounds. This dramatically reduces ground loops and electrical noise, so sensitive electronics receive pristine power and your systems behave more predictably.
• 12V/20A output from 24VDC: a true DC-DC conversion path that delivers stable 12V power suitable for high-end marine electronics and other demanding gear.
• multi-function protection: safeguards your gear from over-voltage, surges and spikes, helping to extend the life of expensive equipment and maintain stable operation even in rough electrical environments.
• on-board regulation and isolation: integrated as a single package means fewer components to fail, simplified wiring, and consistent performance across your onboard power network.
• marine-grade construction designed to stand up to the rigors of sea duty, providing dependable power conditioning in challenging conditions.

How it works in practice

• Converts 24VDC onboard power to a regulated 12VDC output with galvanic isolation for total input-to-output separation.
• Filters line interference, dampens transients, and clamps surges so your navigation instruments, radars, displays and audio systems operate with steadier voltage.
• Functions as a voltage converter, stabilizer, isolator and regulator all in one, eliminating the need for multiple separate devices in your power chain.

Ideal use cases

• Marine electronic systems on boats and yachts that demand clean, reliable 12V power from a 24V sail/or engine battery setup.
• High-end onboard electronics: chartplotters, multi-function displays, sonar gear, communications gear, and premium audio equipment that are sensitive to power quality.
• Any 12V device ecosystem operating within a 24V system where noise, surges, or voltage fluctuations have previously caused instability.

What customers gain by choosing this Intervolt solution

• Peace of mind knowing input and output stay electrically isolated, reducing the risk of damaging expensive gear due to ground loops or interference.
• Cleaner power translates to steadier performance, longer component life, and fewer nuisance resets or erratic behavior in critical instruments.
• Simplified power management with an all-in-one unit that replaces separate converters, regulators and isolation devices.
