DC Power Systems For Mobile Telecom Applications

Harmer and Simmons has introduced two models in a range of DC power systems that enable telecom network operators to reduce energy consumption. Harmer and Simmons is the telecom power division of AEG Power Solutions. Engineered and built with Harmer and Simmons' ecopx architecture, the MPi80HD (8kW) and MPi160HD (16kW) models are designed to reduce electricity consumption, the highest single contributor to mobile telecom operating costs.

The MPi models are said to increase power supply efficiency to 93 per cent due to advanced energy-saving and power-management features. Designed to help reduce electricity consumption and the resulting carbon emissions, Harmer and Simmons' ecopx solutions approach helps communications service providers and OEMs address sustainability issues. Engineered to minimise heat generation while operating in high-temperature environments, the MPi range requires minimal cooling for each base station, further reducing energy consumption and CO2 emissions. The company said MPi systems enhance customers' ability to find solutions tailored to their specific requirements.

Their modular design also reduces lead times by as much as one-half, while simplifying and accelerating maintenance and parts replacement. The initial MPi range 8kW and 16kW solutions will be followed by 40kW to 80kW and 120kW to 240kW models by mid-2010. An advanced controller compatible with renewable energy sources such as solar and wind for hybrid power solutions will also be available by mid-year.

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.
