AUTOMATIC ISOLATION AND BOOSTING TRANSFORMER

ISO-BOOST TM AUTOMATIC ISOLATION AND BOOSTING 
TRANSFORMER FOR 50 & 100 AMP SERVICE

Easy to install and use, operational status is indicated by four lights on the unit, and low-voltage bypass switch provides simple, positive user control. ISO-Boost 50 occupies less space and is easier to install than separate units. Terminal blocks allow for easy customer connections. An optional remote indicator panel permits monitoring of operational status from any convenient location.

ISO-Boost 50 Automatic Isolation and Boosting Transformer is designed to operate on 50 Amp systems. ISO-Boost 100 Automatic Isolation and Boosting Transformer includes features similar to ISO-Boost 50, but is designed for 100 Amp systems.

An ISO-Boost TM Automatic Marine Isolation and Boosting Transformer is essential where long dock runs cause voltage drops or fluctuations in power. The compact unit provides all the magnetic power transfer benefits of an isolation transformer, plus automatically "boosting" low or fluctuating voltages from the dock.

ISO-Boost distances itself from existing designs by meeting all requirements of ABYC E-8.20.1. Transformer windings are encapsulated and the shield, providing safety between primary and secondary windings, is of sufficient ampacity to provide a full fault-current path. In addition, lso-Boost 50 has been subjected to thermal, vibration and shock tests indicative of the marine environment by Underwriters Laboratories, and carries their prestigious Marine UL listing.

Internal circuitry monitors shore and boat voltages, and then adjusts output. The "boost" mode increases the isolated output voltage by 15% to supply appropriate power in the event of low voltage or wire losses during peak power times. If the dock voltage fluctuates above 225 VAC, the unit switches back to the normal isolated output. Mechanically interlocked contactors switch the output between "regular" and "boost" modes, a redundant safety feature that prevents internal shorts and enables a highly efficient voltage transition since there are virtually no losses across the contactors.

Compliance with independent testing lab requirements maximize safety

• Marine UL listing ensures durability and safety

*NOTE: All transformer manufacturers can and do build transformers with a shield between the primary and secondary windings. 

The shields in these transformers are primarily for reduction of the AC line noise from other sources reaching you. Their shields are not capable of carrying the full rated current of the transformer. These transformers do not meet the UL Marine Standard or the ABYC Specifications. This is important because if there is a fault to the shield it may fail before the circuit breaker trips and eliminate the isolation the transformer was installed for. 

If someone quotes you a non-marine isolation transformer, get the name of the manufacturer and the model. Call the manufacturers "TECHNICAL or ENGINEERING" department and verify that their shield is rated to carry the full rating of the transformer. All of the manufacturers we have contacted, except Charles, informed us that their shields do not meet this requirement.
