Teseq Introduces Dual-Voltage Power Source

Teseq has released a dual-voltage programmable power source that is controlled by the company's NSG 3000 series of electromagnetic compatibility (EMC) test generators. The VAR 3005 not only regulates the test voltage but also generates the reduced voltage for the dips and drops testing of equipment under test (EUT). The power source, controlled using either the NSG 3000's front-panel display or the Win 3000 PC software, incorporates internal advanced microprocessor-based electronics.

The unit includes advanced self regulation and several self-test features, including self check, AC power voltage check and phase rotation check, as well as the ability to either inform users of or stop a test if the test conditions are not correct. With electrical performance parameters in compliance with IEC 61000-4-11:2004, the VAR 3005, together with NSG 3040 or NSG 3060 generators, can generate mains dips, drops and variation tests for equipment with a current rating below 16A. The EUT supply input voltage range is from 10VAC to 240VAC, while the output voltage is adjustable from 0VAC to 265VAC.

Based on plug-and-play technology, the VAR 3005 auto-configures tests for the user in order to prevent user errors such as setting voltages out of range. The unit also has the ability to automatically turn off the EUT in the event of a power overload. A single-output source model of the VAR 3005 is also available for applications where dual source is not required.

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.
