Résistances de freinage

We’re offering adjustable and solid resistors, as well as wirewound & tubular power resistors, multilayered power resistors, power resistors in an aluminum casing, high-voltage and braking resistors. The passive components section offers a wide range for engineers from many areas of the broadly understood industry.

• Wirewound power resistors – are resistors made of resistance material as a tape or wire twisted around the insulation corpus, which is usually ceramic. Additionally, we provide wire resistors in an aluminum enclosure, which their rated parameters acquire after installation on a proper heatsink. Wire resistors can be used for overloading devices of a continuous or multi-changing character, and are not useful in case of pulse overloads. There are also types of wire resistors in an aluminum enclosure, which are cooled with water and specially twisted induction-less versions. Wire resistors can be used in stopping electric engines, discharging batteries of condensers, in power electronic devices, and in power electronics: power supply, inverters, and rectifiers.
• High precision metal film resistors – constructed serially or parallelly connected plates. These plates are low-pore chrome-aluminum alloys. The number and type of plates are chosen depending on the required resistance and start power. They’re characterized by a significant pulse overload-ness, thus are often used as stopping resistors for drives with inverters.
