display and control panel

display provides a read-out of both volts and amps for all battery banks. These are driven directly from the shunts mounted in the VSR module via a 4, 6 or 8 core cable with 4 display options, the Bar-graph display includes hi-voltage remote alarm drive.

bar-graph, provides permanent simultaneous volt & amp read-out for all batteries.

digital, provides volts or amp readout with polarity indicator for service battery, other batteries can be checked via selector switches,

digi-bar, combines both a bar-graph display to monitor general status of all batteries, with a digital readout to provide an accurate readout for voltage or current.

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.

control & distribution centre provides a central pre-assembled unit that can be customised to suit a boat / manufacturers requirements including IP65/66 enclosure, the centre offers :-

VSR multi-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.
low voltage power reserve relay pre-installed, provides switch supply to non critical and high load circuits to maintain power reserve for critical circuits, with auto reset .
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.

Introduced in 1981, the P4000 combined all the split charge feature of the P2000, with the power supply protection of the P3000.

Providing in an integrated system in a single package :-

VSR charging to a second or third battery bank, bi-directional, zero volt drop, programmed charge sequence, emergency link starting, voltage switching levels user adjustable.

Low voltage power reserve isolates non-critical circuits at a set voltage, providing a power reserve for critical equipment, while by limiting deep discharge battery life is extended. System provides auto reconnected under satisfactory battery level, and allows for full user control of the system via a choice of remote control panels.

Remote panel provides a display of all battery voltages in the system, with net amperage to service battery, or additional batteries in the system, hi voltage alarm, bar-graph, digital, combined digital and bar-graph display, or an output to suit various analogue meters. Alarm for power lock-out function ( audio / visual ), alarm mute, temporary supply, manual engage, and manual override.

Installation, the system is pre-assembled on a stainless steel mounting plate, that includes control module, relays, shunts and circuit protection to relay drive, electronics and display module. Remote panel provides control functions in one module, interfaced by a 4, 6, or 8 core data cable.

the system provides the boat builder with a single simple to fit “all in one” modular system, for multiple battery bank charging, low battery level power reserve, with remote battery monitoring / control. Over the last 30 years requirements have changed, and the P4000 system has evolved to meet these needs, while still providing maximum flexibility. Allowing a charge / power supply system to be tailored to a boat, not the boat to a split charge units plus additional flat battery protection unit.

By integrating all the functions into a single module, the number of stocked items is reduced, inventory level is reduced, and installation time minimised, while production through-put and value “through the door” are maximised.

interface cable between the display module and the Hall effect shunts / control module, is either a 6 or 8 core cable depending on the system installed, and carries all volt, amp data and control functions. Normal connections are via screw terminal, but for production orders, we can supply systems with standard or waterproof multipole plug and socket connectors
