“CN-A24 Series” DC-DC Power Module of DC 24V Input Type

TDK-Lambda Corporation (President : Yoshiaki Hirota, Head Office : Nihonbashi, Chuoku, Tokyo), a group company of TDK Corporation, starts taking orders for the newly developed “CN-A24 series” of DC-DC power module that is best suited for use in railway related equipment. Order taking will commence on July 20, 2011.

The “CN-A24 series” is a family of DC-DC power modules that is optimal for use in railway related equipment. Both input voltage range (14.4V ~ 36Vdc) and resistance to shock and vibration (EC61373 Category 1 Class B) are compliant with the applicable railway standards. Its high reliability design offers a long warranty period of 5 years. It also features compact size adopting global standard brick sizes. The “CN-A24 series” will be marketed for use in railway related equipment under the brand of “TDK-Lambda”.

Railway related equipment require high reliability and safety due to their nature. So many countries have established safety standards such as JIS of Japan and other international standards (IEC, ISO, DIN, EN, etc.). Railway related equipment are classified broadly into ground installations and railway vehicles and their constructional elements are diversified. As a result, power supplies used for such equipment are in general made custom to fit particular needs. In recent years, as requirements for energy conservation for the sake of environment protection grow, so do requirements for small and efficient power supplies of standard type that are readily available.

Railway related equipment usually use DC-DC power supplies of unit type or PCB type. A module type has been used in communication equipment and other devices that primarily use DC-DC power supplies. In the mean time, railway related equipment have also started to show trends of using small size power supplies. As a consequence, requirement for thinner power supplies such as DC-DC power modules that allow flexible mounting layouts has been growing. With respect to input voltage range, power supplies with input voltage of DC 24V has the second highest demand following the DC 110 type. In response to such market requirement, we have expanded our product family. We expect that the addition of the new CN-A24 series to the existing
CN-A100 series (60-160Vdc) will accelerate the adoption of our DC-DC power modules in the field of railway related equipment.

In addition to marketing them as stand alone models, we will actively pursue to promote them as components of Embedded power supplies* that have high added value to users. We will continue to expand our product family based on opinions of users and pursue this strategic market segment.

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.
