The first solid state shunts were developed by Kddpowercentre in 1990, for Powercentre switch panel battery status displays. Since that date over 5000 have been supplied to production boat builders in the systems various formats.

The system requires no modifications to the engine the engine or charging system, no breaking power cables to fit a resistive shunt, generates no heat, no need for mounting s or protective covers.

The shunt ( sensor ) carries no current, can take an infinite current overload, can drive a bar-graph display direct, providing both amps and voltage readout via a single 3 core cable.

By adding the driver module, the system will drive analogue meter, or a single unit can clone two different value shunts, or drive two or four gauges supplying volts & amps for two battery banks

With only a three or four core cable ( no twisted pairs ) with internal circuit protection, running from 12 or 24 volt supply, the system provides the boat builder with a very cost effective solution to battery monitoring

The driver module takes the voltage from the shunt, and converts it to a FS voltage that matches the gauge. It can be a single amperage, it can also duplicate two different values ( e.g. 30 & 50 amp ), or take the input from two shunts, and drive one or two gauges, or supply V and A on two gauges via a DPDT switch.

Is a encapsulated sensor that fits on the positive battery terminal. It measures the magnetic field, converting it to a voltage proportional to the current flowing. The sensor cannot be overloaded, it carries no current, and generates no volt drop or heat. The unit can also collect battery voltage, and provide circuit protection.

The display is feed direct from the shunt, comprising 3 x 10 dot bar-graphs.  This is either a standard layout for one bank, service and engine bank, or engine, service and bow battery. The amperage display shows net amp, with charge / discharge indicator. Also included is a alarm driver circuit for over voltage alarm.
