Saelig Debuts Packet-Master USB-PET Protocol and Electrical Tester

Saelig Company, Inc. announces the Packet-Master USB-PET - a unique USB protocol and electrical tester capable of performing the suite of tests defined in the USB Implementers Forum, Inc.’s 'Battery Charging, USB On-The-Go and Embedded Host Automated Compliance Plan' (http://www.usb.org/developers/onthego/otgeh_compliance_plan_1_0.pdf). Packet-Master USB-PET is connected to a host PC using a High-Speed USB connection, and controlled using the GraphicUSB application software, which can generate test reports and perform analyzer-style captures.USB-PET’s front panel features a micro-AB receptacle and a D-type connector for connection to a Unit-Under-Test. The rear-panel allows the connection of a meter or an oscilloscope for monitoring, for example, VBUS voltage.

The comprehensive series of tests that Packetmaster USB-PET can perform includes:
  • OTG Compliance Testing:  USB-PET provides automated compliance testing of both the data protocol and the electrical and timing requirements of the 'On-The-Go and Embedded Host Supplement to the USB Revision 2.0 Specification'. All aspects of On-The-Go and Embedded Hosts are tested, including VBUS voltage and current performance, and SRP, HNP and ADP protocols.
  • Battery Charging Compliance Testing: USB-PET can carry out the compliance testing required by the USB Charging Port Compliance Plan, including tests on Charging Ports, Portable Devices, and Accessory Charger Adapters.
  • Analyzer Functionality: USB-PET can capture an analysis of bus activity during the compliance test, in the same format as other MQP analyzers. This allows rapid investigation of protocol-based test failures.
  • Control of Testing: Tests are usually carried out as a suite for a particular type of Unit-Under-Test (UUT) but individual tests can also be selected to investigate a particular failure. Users can even write their own test scripts to modify parameters for more in-depth or special investigations.
  • High Speed Electrical Test Modes: Single click operations allow the initiation of any of the High Speed Electrical Test modes defined in the supplement and the core USB specification.

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.
