Tamura explains how to pick a current transformer
The subject of current transformers is pretty big when you’re talking about inverters and other kinds of power electronics. Tamura’s Craig Simpson went through some examples of that kind of technology in a recent video. Tamura has been making current sensors for over 20 years and have developed quite a few different models of current […]
Surface-mount current-sense transformers handle 40 A at up to 500 kHz
Wurth Electronics Midcom has announced the release of additional Current Sense transformers to the MID-SNS family. “These surface mount transformers are designed to operate between 50khz to 500khz and sense up to 40A of current. The turns ratios offered are 1:50, 1:100, 1:150 and 1:200 with Inductances ranging from 1.4mH to 22.4mH. Compared to current sense […]
Isolation transformers feature touch-safe surfaces
Signal Transformer announces the EcoTrans Standard Series Transformers, which are used to step up or step down voltage, while keeping the mains and output circuits isolated through CE Certified Reinforced Insulation. The EcoTran Series is a UL Listed product to UL 5085-1, CE Compliant backed by TUV Rhineland and meets UL Insulation Class F, as well as […]
Transformers handle PoE++ power levels
A new series of EPCOS transformers is designed for an output of up to 60 W, which are therefore suitable for PoE++ according to IEEE 802.3bt. The new B82806D0060A** series comprises four types with different turns ratios for output voltages of 3.3, 5, 12, and 24 V. The SMD components have dimensions of 30x22x11.4 mm […]
