PoE Mid-Span Device Enables Remote Powering

Phihong's new eight-port power-over-Ethernet (PoE) mid-span can remotely power applications such as wireless access points, computer workstations, security systems and IP cameras with heaters. Designated the POE480U-8UP, the low-cost mid-span provides Ultra PoE technology with 60W of full power per port, delivers total full power of 480W and does not require any power management. Keith Hopwood, vice-president of marketing at Phihong, said: 'The Ultra POE480U-8UP enables the remote powering of high-power devices outside or on the top of a pole without having to run AC power to the location.

'This advanced mid-span technology provides full power on every port and is a more cost-effective solution for expanding your network's capability because it saves thousands of dollars in cost and time when compared to hiring an electrician to install power where it is needed,' he added. The 480W, eight-port Ultra PoE device measures 17.25 x 8.98 x 1.75in (43.8 x 22.8 x 4.4cm). Data networks are available with 10Base-T, 100Base-T and 1000Base-T data rates.

The POE480U features safety and protection systems designed to meet IEEE 802.3 standards, including detection, disconnect and overload control. The outputs are equipped with short-circuit and overload protection and the output can be shorted permanently without damage. Over-temperature protection allows the mid-span to automatically shut down without being damaged. The voltage range of the AC input is 90VAC to 264VAC, with AC input frequency from 47Hz to 63Hz. There is also an optional DC input available.

Even before the PoE Plus standard was approved in 2009, users were requiring applications that require more than 30W of power per port, such as computer workstations, LCD display panels and WAP arrays. Other emerging applications, including emergency lighting security system sensors and medical monitoring, could benefit from combining data and centralised backup power. Phihong's Ultra PoE products can deliver 60W to 80W per port, with the same protection and safety precautions as standard PoE.

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.
