Solutions de prises intelligentes

Les composants de solutions de prises intelligentes de Littelfuse présentent des prises intelligentes et des variateurs de lumière contrôlés par des applications ou une assistance virtuelle. La gamme de produits d’applications de prises intelligentes de Littelfuse comprend des fusibles Slo-Blo® PICO® II 473, des varistances 14 mm UltraMOV, des thyristors de commutation SJ SCR, des triacs thyristors, des pilotes de grille IX4340 et des MOSFET 650 V X2. Les prises intelligentes se branchent sur les prises traditionnelles ou les remplacent et permettent aux utilisateurs de contrôler ce qui est branché à l’aide d’une application ou d’une assistance virtuelle. Les variateurs de lumière intelligents sont également contrôlés à distance. Au lieu de détourner l'énergie de l'ampoule vers une résistance, le circuit moderne de l'ampoule est éteint plusieurs fois par seconde autour de la fluctuation du courant alternatif du foyer pour plus d'efficacité.

SJ SCR Switching Thyristors

Littelfuse SJ Series SCR Switching Thyristors offer designers a wider operating margin than earlier SCRs, making it possible to tolerate insufficient cooling and higher inrush currents at startup. This Littelfuse SCR thyristor series provides a wider operating margin in existing designs and allows smaller heat sinks in new designs. The SJ Series features a robust clip-attach package design that withstands high surges in a choice of five package types. Littelfuse SJ series offers a high junction temperature (T_J) of +150°C, blocking voltage (V_DRM) up to 600V, and current ratings from 4A up to 40A. These thyristors offer a gate trigger current (IGT) of 0.2mA in sensitive gate SCR and between 6mA and 40mA in standard gate SCR.

SJxx40x High-Temperature SCR Thyristors

Littelfuse SJxx40x High-Temperature SCR Thyristors are ideal for uni-directional switch applications such as phase control in heating, motor speed controls, as well as AC rectifier and voltage regulators. The SJxx40x SCRs have a low gate current trigger level of 40mA maximum at approximately 1.5V, with a sensitive version of the series having a gate trigger current of 15mA maximum.

Electrical Vehicle DC Fast Chargers

DC charging stations are designed to convert the electrical grid’s AC power into DC power that can then be fed directly into a vehicle’s battery system for fast charging – in 30 minutes or less. Because the conversion from AC to DC power is being done in the charging station, these units can provide higher levels of power (50kW to 350kW and beyond) to the vehicle compared to AC charging stations. Working with tens to hundreds of kilowatts of power, efficient conversion, reliability of the system, and user safety are critical.
