200W Power Supply Module For Railway Applications

Power supply specialist TDK-Lambda EMEA has added a 200W module to its CN-A110 series of DC-DC power modules, which have a 60-160VDC input to accommodate higher-power railway applications. Available with nominal output voltages from 5V to 24V (adjustable +/- 10 per cent), the CN200A110 module has a wide input range, and is fully regulated and isolated to deliver good performance in the industry-standard half-brick footprint.

The CN200A110 DC-DC modules are suitable for rolling-stock and fixed installations, enabling customers to design cost-effective EN50155-compliant systems without the risks associated with custom product designs and in a shorter timescale. TDK-Lambda also offers a design and manufacture service for customers preferring to buy in complete systems that meet their exact electrical and mechanical requirements. Designed for harsh environments, the 200W module in the CN-A110 series meets the stringent shock and vibration requirements of IEC61737 Category 1 Class B, as well as the Japanese equivalent standard JIS E 4031.

The baseplate-cooled CN200A110 module, with industry standard half-brick pin-out, provides high, true usable power from -40C to +100C, without de-rating. It offers up to 88 per cent power conversion efficiency, 73/in3 power density and delivers up to 4.2A useable output current in a package measuring 57.9 x 61.0 x 12.7mm. As standard, all models in the CN-A110 series are equipped with remote sense, remote on/off and input-to-output isolation of 3,000VAC, as well as over-voltage and over-current protection circuitry. They are delivered with TDK-Lambda's five-year warranty, are safety-approved to UL/CSA/EN60950-1 and carry the CE mark, according to the LV Directive.

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.
