NBK2

Voltage Boost Controller

An add on to most marine isolation transformer brands and models, it automatically compensates for Low Voltage Shore Power conditions by switching an additional boost ratio when needed. Detects dock frequency and automatically switches boost/un-boost voltage thresholds. 

Control, power metering and event logs are accessible via our wireless dashboard or/and an optional 3.5in touch display. Up to 2 automatic boost transformers managed from one interface.

 

The only failsafe product of this class on the market. The perfect retrofit for the Charles Industries™  IsoBoost and PM3 transformers.

AUTO/MANUAL BOOST

Nauti-Boost can be setup as manual or automatic boost. In manual mode it is controlled via Wifi with a phone or tablet and/or via a 3.5" remote touch screen.

COMPENSATE FOR LOW VOLTAGE

Low dock voltage situation triggers the automatic boost.

The systems un-boost when the voltage is back to normal.

AC METERING & EVENT LOG

AC metering with two values. A total (kwh accumulated since the unit is in service), and a "trip" (kwh accumulated from the time the function was reset to zero.)

Time stamped events and alarms are accessible on the screen and/or downloadable from your phone or tablet.

FAIL SAFE

If the electronic controller or the contactor coil fails, only the boost function is disabled, the transformer will still provide power to the boat.
