Connectors Ideal For Hybrid Electric Vehicles

Amphenol Industrial is offering a connector series designed to eliminate bulky and space-consuming cable glands on motors, AC/DC inverters and converters and other high-amperage equipment. The IP67-rated E-Power 400A connectors are rated to 1,000VDC and feature integrated EMI shielding. The E-Power family of connectors is specifically designed to meet the needs of modern electrification programmes in high-voltage and high-amperage applications, such as power converters, hybrid electric vehicles, heavy equipment electrification, two- and three-phase motors and starter generators in the military, aerospace and industrial markets.

The connector series incorporates Amphenol's Radsok contact system to achieve higher current ratings, as well as to lower temperature rise and contact resistance, as compared with other contact methods, in a compact, lightweight package. Radsok technology, an electrical terminal based on a hyperbolic grid configuration, enables lower insertion forces than standard contacts for easier mating. Because it delivers more power in less space, the Radsok contact system eliminates having to run wires through bulky cable glands in traditional three-phase motor assemblies and similar equipment to deliver power.

The result is a more reliable, user-friendly connection with a 40 per cent smaller footprint to reduce the overall enclosure size, while simplifying maintenance issues. Amphenol said one E-power connector can replace three conventional connectors, saving space and cost. Amphenol's E-Power connectors come in two- and three-pin power configurations ranging from 100A through 500A per contact and have the capacity for two small-gauge signal contacts for high-voltage interlock loop (HVIL) purposes. The IP2X style sockets are available in crimp, lug or bus bar termination.

Cable plugs have IP2X style crimp pins and can accommodate shielded wires. Multiple wire sizes from 50mm to 95mm can be used with the new connectors, which feature an all-aluminium shell, strain relief for the jacketed cable incorporated into the shell and good vibration resistance. Radsok utilises the tensile strength properties of the flat, high conductivity alloy grid for the high normal forces required for conductivity, while providing a large conductive surface area. This results in a correspondingly low voltage drop and low temperature rise while maintaining low insertion forces.

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.
