Evaluation Kit Simplifies Converter Application

The 3E GUI Silver Edition evaluation kit has been introduced to simplify the application of Ericsson's 3E DC/DC converters within PMBus systems. The kit has been designed to make it easy for engineers to monitor, program and test the full range of BMR45x-series parts within a representative hardware and software environment. The kit's software package features a graphical user interface that is easy to use and unlocks the power of the PMBus-programmable devices to make even complex applications easily approachable, according to the company.

The kit includes one each of the 396W BMR453 and 240W BMR454 intermediate bus converters, together with one 20A-rated BMR450 and one 40A-rated BMR451 point-of-load regulator. A CD is provided that contains the 3E GUI Silver Edition software package, together with a library of technical papers and supporting information. The kit's evaluation board embeds a USB-to-PMBus interface and accommodates one intermediate bus converter and up to three point-of-load regulators. Designed to maximise ease of use, the board's heavy-duty input and output sockets ease high-current connections to bench power supplies and test loads.

Designers can power the point-of-load regulators, either from the onboard intermediate bus converter or from an external DC supply. The software automatically scans the PMBus for connected devices at power on and continually updates and displays each converter's key operating parameters while the devices are running. A graphic user interface allows users to enter new values for each converter's output voltage, and specify delay and ramp time values for sequencing power supplies in multi-rail applications. It is also possible to define voltage margins to test the susceptibility of load circuitry to voltage variations.

Other facilities include the ability to set independent warning and fault threshold levels for each converter's input and output under- and over-voltages, output current and device temperature. Designers can choose between latched and retry responses for each set of fault conditions. A separate device-monitor window graphs each converter's key operating parameters against its fault and warning thresholds as it runs. Save and load buttons allow users to save or load a converter's configuration at any time to a disk file, making it possible to record and restore setup information at the click of a button.

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.
