New current sense transformers designed for metering applications are unveiled by Tech Power Electronics. These SMT transformers are made from nanocrystalline cores to offer many advantages over traditional current sense transformers such as better measurement accuracy, lesser size and weight and a larger operating temperature range from -40°C to 125°C.
The SCTN10-750, SCTN12-1000, SCTN20-2000, SCTN30-1000 and SCTN70-2500 transformers are specified for a 50 – 400Hz frequency range with a 0.2 or 0.5 accuracy class. All models are RoHS and Reach compliant and designed for 10A, 12A, 20A, 30A and 70A current range. The plastic package for the transformers uses UL94 V-0 materials.
