MOBi MOB Indicator
The Nasa MOBi is a state of the art, fail-safe transponder man overboard system. It consists of a base unit and up to eight active transponders for crew or valuable equipment. In operation the base station sequentially interrogates each transponder which then broadcasts its presence. In the event of a crew member falling overboard the drop in signal level is detected by the base unit which sounds a high intensity audible alarm. To aid identification of the missing crew member the base station continually displays the names of all the crew currently logged on, the signal levels of their transponder fob and their current status. Three AAA cells power each transponder for several weeks of continuous use. Should the base station be turned off the transponders will go to sleep with a life of several years. So if you are sailing with Tom, Dick and Harry don’t forget to take MOBi with you!
EX-1 exhaust temperature monitor/alarm
The EX-1 continually displays the exhaust gas temperature in wet exhaust systems giving advanced warning of potential problems.
The EX-1 measures the exhaust gas temperature directly and displays it in degrees centigrade or Fahrenheit. Once the normal working temperature has been established a maximum temperature, a few degrees higher, can be programmed into the EX-1 which will then sound an alarm if that temperature is exceeded.Even a small rise in temperature can indicate a potential problem such as a minor blockage, leak or failing pump which can be corrected before a complete failure occurs.
I just wanted to share with you another great reason for having the EX-1 fitted. Over the last few weeks of using our boat I observed that the running temperature had gone up around 5 degrees or so. Now with using the boat in the winter one would expect the reverse, so it caused me to think more about it. Added to that, when I did use the engine at full revs on load (something I do regularly just as a check) the exhaust alarm went off (it doesn’t normally.) I then observed the seawater tell-tail was more pronounced (the tell-tail feed is off the line between the Jabsco pump and the inlet to the cooler. Hmmm: possible blockage? I removed the impellor and true enough, one of the vanes had come off. On stripping the cooling system (I was already working on the leaking silencer) I found one part of the impellor up against the tube stack, but more importantly, when I removed the hose feeding the tube stack, via a small elbow, I found a larger part of the impellor jammed inside, reducing the flow by as much as 50% and causing s sediment build up behind it, reducing it further. All cleaned out now, but the reason for telling you is that the EX-1 gave me warning before any real damage could have been caused. It is a brilliant piece of kit.
20W Semi Flexible SOLAR PANEL
At just 3.5mm thin our weather proof panels are tough enough to withstand being stepped on when wearing soft soled shoes
A solar panel can provide a near maintenance free solution to keeping batteries charged when unattended. An occasional wipe with a damp cloth is all that is necessary to ensure the panel continues to trickle energy into the battery. Keeping the battery topped up will improve its reliability and can extend its useful working life. Whilst solar panels give their maximum output in direct sunlight, even an overcast day can provide a useful level of charge.
The Nasa Marine 12 volt, semi flexible solar panel is robustly constructed on a fibre glass substrate and are protected by a scratch proof transparent Tedlar polymer. Only 3.5mm thick and lightweight, they have no metal outer components to make contact with the surface to which they are fitted. The efficient and stable polycrystalline cells are encapsulated between two tough outer layers so the whole panel is weatherproof and carries a limited one year warranty.
The panel can be gently flexed (in one dimension.) to follow a smooth curve, such as a coach roof, by up to 2.5cm per 100cm of panel length. Four, grommet finished, holes are provided for screw fixing. Alternatively panels can be glued into position using mastic. The panels do not contain glass and, when correctly mounted, can be stepped upon when wearing soft soled shoes.
A sealed junction box is fitted with 2.5m of output cable, a connector and fuse protected crocodile clips. Electrical connection is simple though the use of a solar regulator is recommended to prevent overcharge if the system is to be left unattended for long periods or the solar panel to battery ratio exceeds the minimum of 10W to 100Ah. An internal blocking diode prevents reverse current drain at night. The panel is protected with an inline 3 Amp fuse.
The 20W panel measures 510 x 360mm
Compact battery monitor, just 124 x 62mm x 23mm!
Based on the highly successful BM-1 marine battery monitor, the BM-1 Compact is especially designed for applications where space is at a premium.
Caravans, mobile homes, RV’s, small boats and renewable power installations can all benefit from the BM-1 Compact. It is able to monitor the performance of any 12 Volt lead acid battery system with a capacity up to 600 AmpHours. The BM-1 Compact is supplied with a precision 100 Amp shunt and prefabricated cables to enable simple DIY installation.
The unit continually monitors the voltage, the current (charge or discharge) and calculates the state of charge together with the time remaining to charge or discharge the battery.
This information can lead to a more efficient use of the battery enhancing its life and reducing the risk of failure.
Operation is very simple. One screen displays the voltage, current (charge or discharge) and a bar graph showing the remaining capacity. A flashing alarm is also included to warn if the capacity is getting too low. A second screen shows the remaining time available at the current charge/discharge rate together with the remaining capacity in both analog and digital format.
The BM-1 Compact consumes a miserly 1.5mA!
BM-1 Compact is used in various vehicles by the Ministry of Defence.
AIS Engine 3 upgrade processor
The AIS Engine 1 and 2 can be upgraded to AIS Engine 3 specification by replacing the processor. This is a straightforward procedure where the old device is simply unplugged from its socket and replaced by the new device. AIS Engine 3 relays all AIS messages.
