Series Production Start for SEMIKRON SKiiP 4 - The Most Powerful Intelligent Power Module on the Market

SEMIKRON, global leader in the field power electronics, launches series production of its SKiiP 4 line. On the power density front, SKiiP 4 modules outdo all other IGBT modules on the market and feature integrated driver and heat sink into the bargain.

The power components in SKiiP 4 modules can be operated at a junction temperature of up to 175°C. To make sure that these high temperatures can be used reliably, the power components are 100% solder-free. SKiiP4 modules do away with the conventional base plate, reducing mechanical stresses. The use of Skinter sinter technology also means that the solder layer, which can be detrimental to component or module life, is replaced by a sintered silver layer, achieving five times the reliability when subjected to passive thermal cycling. The power cycle is 2 to 3 times greater than that of soldered base-plate modules. In practice this means greater reliability in the field, as well as lower service costs.

The integrated gate driver in the SKiiP 4 sets new standards on the reliability and functionality fronts. The digital driver guarantees safe isolation between the primary and secondary side for both switching signals and all measurement parameters, such as temperature and DC link voltage. This means users no longer have to introduce complex and costly circuit components to provide safe isolation. The SKiiP driver features a CANopen setup and diagnosis channel – a first in a power module – which enables access to an error memory, meaning errors in the SKiiP 4 can be quickly identified and saved for later diagnosis.

Today, many decentralised green power supply systems are monitored for errors remotely. The CANopen interface facilitates the integration of diagnosis functions into the remote control and monitoring concept. Even without direct integration of the CAN interface into the controller, this feature is still very useful as regards on-site service and maintenance tasks.

Besides error diagnosis, settings in the SKiiP 4 driver can also be adjusted. For example, the switching threshold can be adapted to the given application for DC link voltage monitoring purposes.

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.
