The DCR590G65 Phase Control Thyristor is one of our most efficient and dependable high-power Bipolar devices. The device is designed with high surge current capabilities and manufactured in our G outline package. In addition, the device has a chip junction temperature that works reliably within an operating range from -40°C to a maximum of 125°C. The device’s characteristics are well suited for use in the soft starter applications with electric motors. Operating at line frequencies where switching losses are small, the low conduction losses of DCR590G65 enables increased system efficiency. This product offers a number of benefits for end-user applications inclusive of; reduced system cost, improved thermal characteristics, maximized system efficiency and reliable operation in variable environments.
Asymmetric GTOs are divided in two categories: Buffer layer and Standard. Buffer layer GTOs have exceptionally low on-state and dynamic losses. Fine pattern types (5SGF) are optimized for fast switching and transparent emitter (5SGT) for low on-state losses. The Standard GTOs have excellent trade-off between on-state and switching losses.
Mitsubishi Electric Corporation announced the launch of its LV100-type T-series insulated-gate bipolar transistor (IGBT) module for industrial uses. The LV100 package, which achieves high versatility and high current density, has been used widely in railway and electric power applications and now has been adapted for industrial uses. It is expected to help reduce the size and power loss of power converters, specifically inverters used for renewable energy applications such as photovoltaic and wind-power generation, and also high-capacity motor drives.
High performance three phase current sensor +/-1500A. Suitable for high power motor control and inverter applications, with high integration.
StakPak is a family of high power insulated gate bipolar transistor (IGBT) press-packs and diodes in an advanced modular housing that guarantees uniform chip pressure in multiple-device stacks.Although the most common package for IGBTs is the isolated module, for applications requiring series connection, press-packs are preferred because of the ease with which they can be connected electrically and mechanically in series and because of their inherent ability to conduct in the shorted state – an essential feature where redundancy is required. Since IGBTs feature multiple parallel chips, there is a challenge - with conventional press-packs - in assuring uniform pressure on all chips. ABB has solved this problem with a patented spring technology.
The 867A GTO Thyristor, DG646BH25 is among our highest performing and reliable traditional bipolar devices. The device is designed with high voltage and high surge current capabilities, manufactured in our H outline package. This robust device has been a part of Dynex’s long-standing GTO history that are designed to provide both high quality and reliable parts for the maintenance market that exists due to long service life of traction equipment. The DG646BH25 has a turn-off capability that contributes to the reduction in equipment size and weight in addition to, low noise emission to reduce acoustic cladding necessary for environmental requirements. This device has an inherent fast turn-on however, is primarily designed to turn off high current making it useful in PWM and chopper circuits. End user applications can benefit from reduced system cost, improved thermal characteristics, maximized system efficiency and reliable operation in severe environments.
This unit contains 8 individual 12 pulse 700 amp 150 volt DC rectifier assemblies. Fed by a single 900 KVA transformer, these 8 rectifiers are all individually controlled for supplying power to 8 separate sodium hypochlorite generating stations. These produce liquid chlorine bleach and liquid swimming pool chlorine in large bulk quantities.
