Teseq Test System Gets Telecom Surge Module

Teseq has upgraded its NSG 3060 with a simple waveform module that generates an open circuit voltage test pulse of 10/700us to test ports intended for connection to symmetrical communication lines. The telecom surge module - the TSM 3751 - is used in configuration with standard test modules, including EFT and combination wave, to provide testing configurations specifically suited to users' applications. The TSM 3751 enhances Teseq's NSG 3060 test system, which features a modular architecture to cost-effectively meet the needs of basic as well as sophisticated test laboratories.

The module is said to easily fit into the NSG 3060 to provide a fast and convenient test setting that allows users to select source impedance from either 15ohms or 40ohms by simply pressing a button on the generator's colour LCD touch screen. It can also be placed into an expansion housing controlled by the generator's touch screen or via the Win 6000 software. The surge module adheres to several industry standards, including IEC/EN 61000-4-5:2005 and IEC 60060-1, ITU-K series and ANSI/IEEE C62.41.

It meets the latest ISC short-circuit current pulse form requirement of 5/320us, easily satisfies IEC requirements up to 4kV and surpasses the UL 1950 safety test recommendation of 7kV. In addition, when tolerance is taken into account, the TSM 3751 is compliant with ANSI-TIA-968-B, covering the 9/720us pulse form. The TSM 3751 has a voltage range of 200V to 7,700V in 1V steps as well as positive, negative and alternating polarity with floating pulse outputs. Minimum repetition time for voltages up to 4,400V is 20sec and 30sec with a voltage range from 4,401V to 7,700V. Maximum repetition time is 600 seconds. The TSM 3751 has an asynchronous coupling mode.

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.
