New 4 HP Module Width and New AdvancedMC Carrier Mechanics

An enhancement of the fundamental parts of AdvancedMC standard which is an important part of the AdvancedTCA and MicroTCA platform, was published in December 2006. Therefore Schroff have updated their AdvancedMC products, so that they correspond to the newest issue of the PICMG AMC.0 R2.0.

Apart from the change of the identification of the different module sizes, the introduction of a new module width is an important addition to the standard. Until now one differentiated between two AdvancedMC module widths (3HP and 6HP) at two different heights. Now a further module size has been defined, which was derived from demands from the AdvancedTCA standard and the integration of operating systems, which take up more than 3 HP, and the fact that with a 6 HP module too much space would be "given away". The new in between size (4 HP) is called Mid-size and makes, for instance, the installation of larger MicroTCA power modules and the use of small cooling units possible. In their mechanical construction the new Mid-size modules (4 HP) are identical to the existing Compact (3 HP) and Full-size modules (6 HP).

The front panels available for the individual module sizes can be obtained from Schroff's Front Panel Fast Track. Here, the possibility for individual design (modification, customer specific outbreaks, foils and silk screen printing) and the production of front panels within a very short time (delivery from 2 days ex works) is on offer.

The Schroff locking mechanics of the AdvancedMC modules were not affected by the standard issued in December. As a special service the module handles can also be manufactured and supplied in customer specific shapes and colours.

Following the new module width Schroff has developed specific AdvancedMC Carrier mechanics, which only receives Mid-size modules. This Carrier is comparable to a small frame-type plug-in unit, which is inserted into the AdvancedMC module. The Carrier itself is hot-swap capable and is inserted into the AdvancedTCA systems like a plug-in unit, whereby the dimension of an AdvancedMC Carrier corresponds to that of an AdvancedTCA plug-in unit (8 U, 6 HP). For the mounting of the Carrier in the system the same parts, screws, centring pins etc. are used. This also applies to standard AdvancedTCA extractor handles. Therefore the Advanced Carrier plug-in unit has the same appearance as a normal AdvancedTCA plug-in unit.

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.
