analogue meter driver converts the signal from the Hall effect shunts to drive a range of analogue meters, units are available to provides up to 3 voltage and 2 ammeter drives from a single analogue meter driver module. The unit can be supplied for a wide range of meter FS mV and amperages ranges.

bank charging has it’s roots in the system introduced in 1980, but now with 30 years test, development, and experience gained from it’s fitment to 1000’s of production boats. It is a combination of what is new, Hall effect shunts, internal circuit protection, and the old such as pulse start- up for initial high charge current into low capacity batteries. Reducing alternator stress, improving battery recharge cycle, and avoiding relay chatter. - integral Hall effect shunts are pre-
installed providing net load (charge or discharge) for one or two service banks, if a remote bow battery is fitted it will provide charge amps. The shunt cannot be overloaded, and one unit will cover all displays types. - emergency link start will, at the press of a button at the engine starting position, allow the engine to be started (for 90 seconds timed period) from the service battery or a second engine battery if fitted.
- power connections only require high power links from the battery isolator switches, service power distribution point, and a low power feed from the common battery negative for electronic and control systems.
- display feed provides all battery voltages and amperage to feed the display module, the connector is a screw clamp normally, but standard or water proof multipole connectors can be supplied on production orders.
- circuit protection is provided for relay drive circuits, internal electronics, and all feeds to the display module, via internal resetable circuit breakers. If a short or over current situation occurs, the circuit breaker will isolate that circuit until the fault is removed, power supply will then automatically be returned.
- voltage adjustment is provided for all charge voltage switching levels, allowing the system to be tuned to suit a particular installation.

- alternator permanently linked to battery
- dual voltage monitoring

- water protected modular construction
the system provides the boat builder with a single simple to fit “all in one” modular system, for multiple battery bank charging. Over the last 30 years requirements have changed, and the P1000 system has evolved to meet these needs, while still providing maximum flexibility. By continuously developing the system, such as Hall effect shunts, it allows a complete system to be tailored to a boat, not the boat to a split charge unit.
By integrating all the functions into a single module, the number of stocked items
is reduced, inventory level reduced and installation time can be minimised, while

When the P1000 system was introduced in 1980, the main split charging options were blocking diodes or relays controlled by the alternator warning light, neither an efficient charge system. The P1000 was the first full function VSR ( voltage sensed relay ) split charge system, providing charge to a second battery bank, when it sensed the engine battery had achieved a satisfactory charge level. Automatically isolating the batteries when the engine was stopped, or the system identified a possible system fault. During the next 5 years the range increased to the P5000 system for 2 engines / 3 battery banks, introduced in 1985.
Over the years the systems have continued to evolved via a rolling programme of testing and development, plus 30 years of product feedback which has resulted in the current range, and the next generation to come.
