The installation of the Galvanic Isolator between the AC safety ground and DC bonding system blocks out most of the low voltage currents and corrosive action seen on the vital metallic components in the saltwater.  With the low voltage current blocked, the galvanic corrosion effect on the sacrificial anodes is significantly reduced (while the integrity of the critical safety ground path is maintained.) This means a significant saving in boat haul-out fees and zinc replacement costs. For additional safety, all units feature a large capacitor, providing a secondary low-impedance path for sending AC current to the ground. 

Newmar’s latest galvanic isolator meets the latest ABYC A-28 2019 including being failsafe. This new design can meet the strictest temperature and current tests to create a robust solution for galvanic protection.

KEY FEATURES

• Protects against corrosion
• Maintains a safe environment
• Certified to UL1500 standard for Ignition Protection
• Tested to 50°C ambient temperature
• The fail-safe feature ensures ground maintenance
• Connection in the event of isolator failure

These “UP” converters produce 24 volts from 12 volt systems and are ideal for managing dual voltage applications on marine vessels without having to install a 24 volt battery and dedicated charging system. Choose from two types depending on your application:

In the Standard, Non-Isolated Series the 12V input and 24V output share a common negative ground and are ideal when installing certain electronics that operate better on 24 volts when a robust 12 volt system exists. Models available in outputs of 7, 16 and 25 amps.

The Isolated Series allows compatibility between positive and negative ground systems, for example installing negative ground 24V electronics on a 12V floating ground aluminum vessel. The isolated series is also a good choice for dual voltage system where noise and interference is an issue. Its input/output partitioning circuit prevents noise on the 12 volt system from being transmitted to the 24 volt side.

Standard, Non-Isolated Series
