Calex Launches Chassis-Mount DC/DC Converters

Calex Manufacturing has announced the HCM series of high-power density chassis-mount DC/DC converters. The 150W rugged encapsulated DC/DC converters are ideal for harsh industrial and commercial off-the-shelf military applications. All 10 models in the series offer a 4:1 input range, from 9-36VDC and 18-75VDC, which makes the units suitable for 24V industrial, 12V and 24V battery applications and 48V power sources. The output voltages available are 3.3, 5, 12, 15 and 24VDC.

All models are isolated input to output. The mean time before failure for all models is more than one million hours and all models are backed by Calex's five-year warranty. The enclosure of the HCM series provides a 'clamp'-style recessed barrier strip, which secures wire without twisting. The enclosure can be mounted with the barrier strip facing up or down, depending on what is preferred for the application.

The thermal characteristics of the enclosure are said to provide a favourable 3C per watt dissipated thermal impedance. The enclosure also has threaded inserts for securing a heat sink if needed for extended temperature applications. The case operating temperature range for the HCM is -40C to +100C. The case dimensions are 4.3 x 3.2 x 1.0in and the weight is 11.4oz. RoHS and non-RoHS construction is available.

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.
