PRESS RELEASE FOR IMMEDIATE RELEASE – April 2015 For Editors GMR Current Sensor – CSC-1U – for Smart Metering Willow Technologies Limited (www.willow.co.uk) introduces the new Yamaha CSC-1U Current Sensor IC. The device gives high accuracy electric current measurement by using high sensitivity GMR elements. Available in a SIP4 package, the CSC-1U can be used with AC or DC and provides a ratio-metric or non-ratiometric analogue voltage output. With no Ferrite core required, any design using this IC will provide a compact package (IC size 5x4mm approx.) which is driven by a 5VDC power supply. Partnering the IC is a packaged version complete with bus bar, which is capable of measuring up to 50Amps with a sensitivity of 28.3mV/A typical. Custom bus bar package designs can be considered which would increase the measuring range dramatically and Willow welcomes any enquires of this nature. Martin Pearce, Marketing Director at Willow Technologies Limited commented “Present demand for these highly innovative current sensing assemblies stems from the automotive, industrial, electric utility and home electronics (electric tools) markets, with applications ranging from monitoring of auxiliary and electric vehicle batteries, inverters for motor driving, power conditioners, smart meters and energy management systems.” CSC-1U exhibits excellent performance over a wide temperature range with offset temperature drift less than +/-6mV and sensitivity temperature drift of less than +/-1%. Linearity is 0.05%FS (max.) with response time at just 1.0µs and frequency response of 400kHz. Current consumption is very low at 6mA for 0A and 16mA for 50A. Yamaha continues to develop ever improved current sensors and current sensing assemblies, their technology is highly regarded globally. “Based on the excellent quality and performance of Yamaha’s current sensing range, we are confident at Willow Technologies that this product will fast become a leading player in the market”, concluded Pearce.
