Low-Profile Power Supplies for Operator Panels

Phoenix Contact has launched the low-profile Step power supply, which has an assembled depth of 61mm and is suitable for installation in small distribution boards and operator panels. Mounting is flexible as the power supplies can be installed onto DIN rails or directly fixed onto plane surfaces such as walls. For even lower-profile applications or for horizontal mounting, the latest addition to the Step range is a 24DC 0.75A rated power supply, which has a depth of 43.5mm.

The compact 36, 54, 72 and 90mm modules cover the complete voltage range of 5, 12, 24 and 48VDC. The more common 24DC output voltage devices are available with outputs ranging from 0.5A to 4.2A, while the 12DC output devices deliver 1.5 up to 5A. Worldwide use is possible thanks to a wide-range input of 85-264VAC and 95-250VDC and a broad temperature range of -25C to +70C. A long mains-failure bridging allows the power supplies to support loads reliably during short-term mains voltage fluctuations.

Another feature for all but the 36mm-wide versions is that the rated output voltages of 12 and 24VDC can be continuously adjusted via the front-side potentiometer from 10-16.5VDC and from 22.5 to 29.5VDC in order to compensate for voltage drops on long cables. The reliable power supply units also feature parallel connections for increased performance and redundancy.

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...

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...

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.
