    ANG ISO-Boost Transformer

    The perfect replacement for your old Charles ISO-boost Transformer

    Marina’s power supplies aren’t always reliable. Fluctuations in voltage can occur due to high demand or aging infrastructure, resulting in either insufficient or excessive power delivery to your boat. Additionally, corrosion or damage to shore power connections can cause poor conductivity and interruptions in the electrical supply. Even inadequate maintenance of marina’s power systems can lead to failures or unsafe conditions, putting your vessel’s onboard equipment at risk.

    To protect against these issues, you need a marine isolation boost transformer.

    NEW EVOLUTION VERSION
    Same exceptional features in a lighter version, smaller dimensions, and updated display panel.

    ANG ISO-BOOST™ 50-60Hz

    If you’re looking for a dependable solution to keep your yacht’s onboard equipment running smoothly, the ANG Isolation Boost Transformer (ANG ISO-BOOST™) is the perfect choice. Featuring an integrated isolation transformer with a voltage boost circuit, it automatically provides the correct line voltage to your yacht’s electrical system, delivering complete safety and protection against damage from excessive voltage increases and unexpected shutdowns due to voltage drops.

    The ideal replacement for Charles Iso-Boost Transformers, ANG ISO-BOOST™ Transformers are lighter, include more standard features, and are available in seven models. Each unit is equipped with a toroidal transformer, which offers significant advantages over traditional laminated transformers, including higher efficiency, a more compact footprint, lower operating temperatures, and silent operation with no vibration or hum.

    FULLY AUTOMATIC

    Also available in European version: ANG ISO-Boost 9 Kva & 18 Kva with the same features of the US version, but suitable for European boats.

    Moreover, the ANG ISO-BOOST™ Transformer is lighter than the Charles ISO-Boost. It is available in seven models, each equipped with a toroidal transformer—the latest generation and highest-quality transformer technology on the market.

    In addition, the ANG ISO-BOOST™ features three boost steps (two steps up: 15% and 7.5%), whereas the Charles ISO-Boost offered only two steps (one step up at 15%). The boost steps on the ANG ISO-BOOST™ are also adjustable, a capability not available with Charles isolation transformers.

    Our Marine Isolation Boost Transformers (IsoBoost) automatically deliver the correct voltage to onboard equipment while preventing shutdowns during sudden voltage drops and protecting against damage caused by excessive voltage increases (within the specified range).

    The output voltage is automatically boosted if the supplied voltage is too low.

    In short, ANG Marine Iso-Boost Transformers ensure comprehensive protection for all your marine electrical systems.

    ANG ISO-BOOST™ has the static system with Seamless technology, the soft start, auto-restart and by-pass systems as standard features, while for the Charles Iso-Boost these were all optional.

    ANG ISO-BOOST™ Features

    FULLY AUTOMATIC OPERATION: The ANG ISO-BOOST™ operates entirely automatically for maximum convenience and protection.

    OVERLOAD ENDURANCE: Designed to withstand a 30% overload for at least one hour.

    ELECTRICAL PROTECTION: Equipped with a protective shield, the shore grounding conductor connects to a barrier between the primary (shore) and secondary (boat) transformer windings. This shield ensures electrical isolation and protection onboard.

    BY-PASS SYSTEM: Includes a manual bypass system that allows you to disconnect the boost mode in case of a fault and supply power directly from the shore while maintaining electrical isolation.

    SOFT START SYSTEM: A soft start system minimizes current inrush during startup, protecting connected equipment.

    FULL OUTPUT POWER GUARANTEED: Delivers full output power even in boost mode, with consistently stable voltage.

    AUTOMATIC THERMAL PROTECTION: Integrated thermal protection automatically shuts down the system if temperatures exceed safe limits. The unit restarts automatically once normal operating temperatures are restored.

    AUTO-RESTART: The system automatically restarts after high voltage, low voltage, blackout, or overload conditions. ANG ISO-BOOST™ uses very low peak transformers to prevent electrical surges.

    COOLING FAN SYSTEM: Equipped with a robust forced cooling fan system to maintain optimal performance.

    STATIC SYSTEM: The static switch requires no maintenance, except periodic filter cleaning.

    ADJUSTABLE BOOST STEPS: Boosts output voltage in two adjustable steps:
    • 1st Step: +15% (from 175V to 209V)
    • 2nd Step: +7.5% (from 210V to 227V)
    • 3rd Step: Non-Boost Mode (shore supply from 228V to 253V)

    This results in a more balanced power supply, eliminating over-voltages in the 200–205V range and increasing voltage within the 205–227V range.

    EUROPEAN VERSION AVAILABLE: The European models (9 kVA and 18 kVA) offer the same features as the U.S. version, optimized for European vessels.

    ALUMINUM CONSTRUCTION: Lightweight, corrosion-resistant aluminum housing for long-lasting durability in marine environments.

    ANG ISO-Boost™ FUNCTIONING

    voltage regulator converter in ft lauderdale

    ANG ISO-BOOST™ covers a wide voltage range gradually increasing the output voltage.
    ANG ISO-BOOST™ is designed to power the boat from a nominal voltage of 120/240 V with three operating thresholds:


    • Shore Voltage from 178 to 209 V (+/- 3V): output voltage from 210 to 240 V (+/- 3V)
    • Shore Voltage from 210 to 227 V (+/- 3V): output voltage from 224 to 242 V (+/- 3V)
    • Shore Voltage from 228 to 253 V (+/- 3V): output voltage from 228 to 253 V (+/- 3V)

    If the input voltage is less than 178V or higher than 253V, the output is deactivated.

    ANG ISO-BOOST™ guarantees the maximum output current even in boost mode.

    ANG 25kW ISO-BOOST, I could not be happier!

    PSA, I had posted a few weeks ago about Charles ISO Boost repair or replacement. Well we found out Charles does not service these anymore as they are no longer in the marine business. After an exhaustive search it boiled down for me between Hubbell, ASEA, and ANG Power Systems. For various reasons I picked the ANG 12.5KW unit. Just finished installing it and I could not be happier! Well made and ready to go. I happened to be in Florida so I picked mine up in person in Ft Lauderdale. They were super friendly, demonstrated the unit, then we talked through the wiring. If you’re looking to replace your unit and want that on board automatic boosting I highly recommend this one. 208.6V input from my shore pedestal and 239V at my AC panel.

    Easy to Install

    The ANG-BOOST is provided with input and output cable glands, conveniently located in the back of the unit.
