CPT7B48 DC/DC Converter Suits DPA Applications

The CPT7B48 Cool Power Technologies 12V, 7A 16th brick DC/DC converter, which is suitable for distributed power architecture (DPA) applications or as a fully regulated intermediate bus converter. This open-frame module, which is available from Semiconductor Circuits, provides a full 84W of 12V power at 55C and 200lfm of airflow. It is compliant with DOSA footprint and interface standards, has an input voltage range of 36 to 75V DC and provides 2,250V DC input to output isolation.

The CPT7B48 is a high-efficiency module with efficiencies exceeding 93 per cent from half load to full load. It meets EN 60950 basic insulation requirements and is UL94 V-0 flammability rated. The module complies with all of the typical industry requirements including no-load operation, 100V/100mS input voltage transient and pre-biased load startup.

Other features include: fixed-frequency operation, auto-restart OVP, OCP and OTP protections, UVLO with 2V hysteresis, remote sense and +10/-20 per cent output voltage trim using industry-standard equations. Remote on/off is standard with positive or negative logic options available. The module features a standard 16th brick pinout and dimensions of 1.3in (l) x 0.9in (w) (22.9 x 33mm) It has a maximum height of 9.5mm (0.375in), which accommodates tight card spacing with minimal airflow blockage of downstream components.

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.
