👁Overview
The MD81/24 is a power supply unit which operates from a ship’s 110 V / 220 V ac 50 / 60 Hz single phase supply and provides a 24 V dc output. The MD81/24 can also be factory configured to provide ‘S’ Type 35 V, 50 V or 70 V dc outputs for legacy equipment (option).

The power supply unit has an automatic changeover facility to switch to the ship’s backup (standby) 24 V dc supply in the event of a main power supply failure. It incorporates a power failure alarm circuit which meets IMO recommendations. Power failure is indicated visually on the front of the enclosure and a relay contact is provided to activate an external alarm system if required.

Constructed in a robust die-cast aluminium enclosure and finished in RAL9005 Jet Black fine texture paint, the MD81/24 is designed to complement existing marine navigation equipment. The MD81/24 is supplied with fixing centres for bulkhead mounting.

Compact and rugged, the MD81/24 offers a power supply solution for locations where space is limited.

The MD81/24 Power Supply from Marine Data: flexible in application, easy to install and simple to maintain.

✅Special Features
Linear power supply with low EMC emissions and high immunity
High surge current capability

The T300B is a compact and rugged SOTDMA AIS Transponder, designed for the demands of the small commercial boat, fishing boat and leisure markets.

👁OVERVIEW

The T300B is a compact and rugged SOTDMA AIS Transponder designed for the demands of the commercial boat, fishing boat and leisure markets. It meets the Class B (SOTDMA) standard, allowing vessels that are not required to fit Class A units to voluntarily fit an AIS Transponder.

When connected to an external VHF antenna and a GPS antenna (not supplied), the T300B will transmit its own vessel position and data and also receive information from other AIS vessels, shore stations and navigational aids within VHF range.

The unit is initially programmed by the user with the supplied software over a USB interface. The T300B is compatible with a range of computer based navigation programs and chart plotters, that can accept AIS data sentences over a NMEA 0183 or NMEA 2000 connection.

✅FEATURES

SOTDMA Transmission Standard
NMEA 0183 and NMEA 2000 compatible
Compact Aluminium Housing
Ideal AIS receiver for Commercial boats and Leisure Craft
Automatic transmission of vessels own position, speed and heading to other vessels within VHF range
Transmitter off facility to conserve power, or for covert use
The ability to plot the progress, changes in heading and speed of other AIS vessels on a PC or Chart Plotter
A method of monitoring the position, speed and heading of other AIS vessels within VHF range

✅APPLICATIONS

Commercial boat, fishing boat and leisure markets
Meets the Class ‘B’ SOTDMA international standard
