RSD-300 Series (300W DC/DC Enclosed Type Railway Power Supply)

MEAN WELL expanded their railway power supply family and introduced RSD-300 series (300W). With the different wattage models of 100W/150W/200W/300W available, MEAN WELL’s complete product line of enclosed type single output DC/DC converter can fulfill the various requirements of vehicle applications. Featuring with 2:1 (±40%) wide input range and 4000VDC input/output isolation, RSD-300 series are characterized by 5G anti-vibration ability, wide range working temperature of -40~+70℃, protections for short circuit, overload, output over voltage, over temperature, and input reverse polarity, as well as built-in constant current limiting circuit and 40mm low profile design (1U compliance)…etc.

With up to date high efficiency circuit design, RSD-300 series possess up to 91% of high efficiency. All series are semi-encapsulated for PCB protection to provide the basic ability of anti-moisture, anti-dust, heat dissipation as well as anti-vibration. Therefore, they can be cooled without any forced-air but still work between -40℃ to +70℃ ambient temperature, which perfectly fit in with the applications of harsh environment. The design of these new converters are refer to ITE standards (IEC60950-1 and EN55022) and also comply with railway certificates (EN50155, IEC60571, IEC61373, EN50121-3-2), so that they are suitable to be used in all kinds of vehicles that equipped with DC power source. The applications include railway, metro rapid transit system, subway, bus, leisure trailer, and vessel...etc. In addition, along with external batteries as the energy source, they are also suitable for harsh industrial installations that concern about dust and moisture, such as security system, DC UPS system, and telecom equipments...etc.

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.
