Power Supply Units Suit CompactPCI Applications

Schroff UK has expanded its 19in Maxpowerpro range of switched-mode power supplies with the addition of the 13100-145 - a 6U model designed for high-power CompactPCI applications. The 13100-145 power supply features an output voltage of 500W and operates from a wide input voltage of 90-264V AC with PFC. It delivers output voltages of 5V, 3.3V, 12V, and -12V.

As well as incorporating a P47 connector conforming to the PICMG 2.11 CompactPCI specification, the PSU also provides the high levels of reliability demanded by typical CompactPCI applications in the communications, industrial, military and aerospace sectors. Inputs are protected against voltage transients and high inrush currents, outputs are protected against open-circuit and short-circuit conditions, and the power supply also includes over-temperature protection.

The unit is hot-swappable and active current sharing is provided on three of the outputs for parallel operation of multiple units in n+1 redundant designs or in systems requiring a higher output power. Measuring 6U high x 8HP wide x 172mm deep, the PSU is supplied with an EMC seal and a 19in front panel including handles. Schroff said the power supply achieves a typical efficiency of 84 per cent and meets the requirements of the relevant standards covering safety, EMC and mechanical stress.

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.
