Power module targets vehicular brushless-motor apps
ON Semiconductor has further expanded its portfolio of automotive Power Integrated Modules (PIMs) with the introduction of the STK984-190-E. Optimized for driving 3-phase brushless DC motors in modern automotive applications, this module contains six 40 V, 30 A MOSFETs configured as a three-phase bridge with an additional 40 V, 30 A high-side reverse battery protection […]
Power quality analyzer checks three-phase lines—and doubles as BS detector for false energy efficiency claims
If you want to really see what’s happening on power lines, you need an instrument that can generate a phasor diagram of the line voltages and currents. An instrument able to do that and much more recently became available from Keysight Technologies. Engineers can use the firm’s IntegraVision PA2203A four-channel power analyzer to observe three-phase […]
High-voltage fuses pop quick
Littelfuse, Inc. has introduced the 487 Series Fuse, the first fast-acting fuse from its 5x20mm fuse family with both 420V AC and 420V DC ratings. In contrast with existing fuse solutions that cannot meet high-voltage and short-circuit test requirements, the 487 Series protects telecom power supply units and datacenter server power applications where a high-voltage […]
