Rectifiers Offer Speed and Weight Improvements

Campbell Collins, a supplier of power supplies, capacitors and hi-rel power semiconductors, has introduced a new range of hyperfast, soft recovery, nanospeed and nanosize rectifiers from SSDI. The 1A, 9-nanosecond SHF1100 and SHF1150 series offer voltage ratings of 100 and 150V respectively. With its void-free glass ceramic package, this series of rectifiers provides a more rugged construction than similar 1N6642 rectifiers.

In addition to its faster recovery time, the SHF1150 is also lighter than 1N5806 rectifiers. Both the SHF1100 and SHF1150 are offered either in an axial leaded package or a surface-mount square tab package for ease of manufacture, and utilise high-temperature metallurgical category 1 bonds and solid silver leads. Designed for high-efficiency applications, the devices offer forward voltages of 0.5-0.975V (dependant on load) and have an operating temperature range of -65 to +175C.

Together with the demonstrated radiation tolerance of these devices, tested up to 200kgy, this also makes them suitable for space applications. The devices will be made available in single-phase, three-phase and diode-array configurations. Screening is available to TX, TXV and S-Level requirements and samples are available on request from Campbell Collins for qualified opportunities.

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.
