Ethernet Switch Chip For Green Broadband Networks

Trendchip Technologies has announced the TC2205F Ethernet switch chip designed specifically for telecom service providers deploying broadband access platforms. This switch chip has four automatic energy-saving 10/100M Ethernet ports, meeting the IEEE 802.3az industry standard and can also detect network cable length and unused network ports in order to manage power consumption. Using these technologies, telecom service providers can start deploying green energy-saving broadband networks while users can also save energy and reduce carbon emissions without their broadband access being affected.

The TC2205F has four 10/100M ports and one MII/TMII (Turbo MII) MAC interface, which is connected to the main CPU on the platform, and the 64-pin QFN packaging requires only half the number of pins in traditional switch chips. The TC2205F combines a series of automatic energy-saving functions such as a low energy consumption mode with automatic entry and exit based on actual network traffic (Low Power Idle), and automatic detection of network cable length and unused ports to reduce unnecessary power consumption.

In addition to energy conservation, TC2205F also offers the QoS, VLAN, and IGMP V1/V2/V3 functions with full and flexible settings in order to satisfy the advanced network settings requirements of telecom service providers when deploying Triple-Play, and ensure the stable quality of video services.

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.
