The monitor range, finds it’s roots in the bar-drivers designed in 1990 to power the status displays on powercentre switch panels. Over the years they have been expanded to drive digital meters, bar-graphs, and analogue meters. They only measure magnetic fields, thus they cannot be overloaded, and generate no heat. The AC shunts convert the current to a dc voltage, and drive similar meter options as the DC units, with the addition of frequency. All outputs can be monitored to provide an alarm system, or interface with the P1 control systems.

AC shunt systems, these operate on the same principle as the DC shunts, and supply data as a dc signal. The units can be supplied as shunts only, or with AC voltage pick, data is supplied to the display via a 3 core cable as per the DC shunts. Output is dependent on display to be driven.

Display systems, since 1990 we have built combination displays, a mixture of digital / bar-graph. The digital allows accurate readings when you need it, the bar-graph giving at a glance monitoring of all functions. We can supply volts, amps, and frequency readings, DC or AC,  units being interfaced with our solid state shunts,  units can also be supplied with alarm functions.

Alarm systems, are normally built to specification, and can cover most functions. For example to monitor the operation of four bilge pumps, and drive a audio / visual alarm, at helm and flybridge.

DC shunt systems, all models measure the magnetic field around the conductor, so have infinite overload, and are currently available in two options.  Stud, fit on an adaptor on the battery terminal, and supply a driver module. This module has one or two inputs, and two outputs driving two meters, or two amperage ranges. In-line, these modules fit on to the power cable, and drive the meter / display direct. Shunts are set up to drive the ammeter, i.e. one module can drive either, a 30 or 50 amp 75 - 0 - 75 mV meter. Both types can be fitted with battery voltage pick up.

Custom systems, cover anything you can think of, that we have not already covered.

Amp hour monitor, a range of modules that are intended to interface between our range of DC electronic shunts, and bar-graph display modules, fitting both current or previous production units.
