Solid State Supplies Increases Marine Safety with New AIS Search and Rescue Transmitter Processor

Solid State Supplies has introduced a new cutting-edge Marine AIS Search and Rescue Transmitter (SART) baseband processor. CML Microcircuits’ CMX7045 is a highly integrated and flexible device that employs a 9600 baud GMSK modem for the transmission of formatted AIS data.

In addition to providing the core AIS-SART formatted data functionality, the CMX7045 incorporates a number of auxiliary operations that assist in the overall system implementation and reduce component count and cost. These include: PA Ramp automation, ADC for battery monitoring, system PLL clocks and four DAC outputs for general purpose and visual indicator use. Engineered for total reliability, the CMX7045 is manufactured using CML Microcircuits’ FirmASIC® technology to fully meet IEC 61097-14 standards, and provides outstanding performance, very low power operation and the fastest time-to-market for the designer.

To further support its applications as a marine safety device, the CMX7045 offers low power sleep modes to ensure maximum safety-battery life and is available in small 48pin VQFN/LQFP packages.

Editors’ Note: An AIS-SART is a self-contained radio transmitter that is deployed by a survival craft or distressed vessel to notify its position for the purpose of rescue. In a rescue situation, the self-contained radio transmitter repeatedly transmits its updated position reports using a standard Automatic Identification System (AIS). Position and time synchronisation is derived from an onboard GNSS receiver (e.g. GPS). Every minute the unit transmits multiple position reports to maintain a high probability that at least one of the position reports is sent on the highest point of a wave, guiding rescue services accurately to its location.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
