EASY LIGHT LED Luminaire
The NASA Marine 12 Volt Easylight luminaire contains 48 high efficiency LEDs in a slender surface mounting package.
The cool white version (CW) is recommended where maximum illumination is required and the warm white (WW) where a more natural light is preferred. Light output for the (CW) is typically 300 Lumens and typically 250 Lumens for the (WW).
The unit is designed for surface mounting directly on a ceiling or wall using the screws provided. It is not waterproof and is intended for use in a dry cabin only.
When fitting ensure that the ventilation slots are not obstructed and take care not to over tighten the screws. When in operation the space behind the unit may get warm so avoid mounting on surfaces where this could cause a problem.
The power leads can be taken through a convenient hole in the mounting panel or alternatively through one of the end vent slots. Connect to a 12 volt DC supply via a suitable switch and a 1 Amp fuse. The red wire goes to the positive supply connection and the black wire to negative. (An internal diode protects the unit against supply reversal.)
HF3W SSB Receiver
TARGET HF3/P & HF3/W
The Target HF3 is a masterpiece of R. F. engineering covering the entire spectrum between 30Khz to 30Mhz. For those new to single side band reception the unit comes complete with everything needed to ‘get on the air’ including a comprehensive instruction manual which includes a list of useful marine frequencies.
Controls on the front of the receiver change reception mode, from a narrow filter for SSB reception to a wide filter which enables high quality audio signals to be heard from broadcast stations around the world. They also control ten memory channels to store your favourite frequencies.
The large, clear liquid crystal display shows the precise frequency tuned to and there is no need for constant ‘correcting’ with the tuning knob so often associated with SSB signals as the receiver
is fully synthesised.
The Target HF3/P has a fixed level audio output to connect to third party weatherfax software. The receiver is supplied complete with a basic long wire antenna, 12 volt power cable and instruction book.
The HF3/W is complete with CD software and interface cable for connection to a PC sound card. The software enables reception of weatherfax pictures, Radiotelex weather forecasts and Navtex. Simply install the software, plug in the supplied cable to the receiver output and PC sound card to receive weatherfax pictures and forecasts from around the world.
Requires PC Windows XP to 7.
H Vector Navtex Antenna
Conventional navtex antennas respond to the electrical component associated with the navtex radio signal. They usually perform well at sea where electrical interference is low but can sometimes be overwhelmed with interference especially when in harbour and connected to shore power.
In most small craft the electrical system acts as an effective ground for the antenna but it can also be a source of interference conducted from other electrical equipment on board. Electrical interference can result in poor reception especially in a marina where the ambient level is high or at sea when poorly suppressed electrical equipment is in use.
The omnidirectional H-Vector antenna is not sensitive to electric fields but to the magnetic component of the navtex signal. As a result it is less sensitive to locally generated interference and, as it does not need a ground, it is not affected by conducted ground interference whether in harbour or at sea.
The net result is that, under adverse conditions, the H-Vector antenna can deliver a significant improvement to navtex reception. The mushroom shaped antenna is compatible with the Clipper navtex, series 2 Target navtex and with the navtex engine. It can be mounted on a cabin roof or rail mounted using an appropriate threaded antenna base.
Semi Flexible SOLAR PANELS
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 panels are 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 panels 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 10W panel measures 370 x 280mm
The 20W panel measures 510 x 360mm
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.
