Current sensor offers MTTF of over 6,000 years

The report also outlines the scope of the testing, reference standards, set-up, procedure and results of the tests. Data analysis and findings of these tests, which were based on actual average environmental conditions in the US, support previous claims that Pulse's Sidewinder current sensors can provide the reliability needed in commercial and high reliability applications, such as outdoor electric metering equipment.

Pulse's Sidewinder AC current sensors provide a highly linear output voltage over a very wide dynamic range of 0.1-1000A. They are used in applications such as distributed power generation, renewable energy and storage, load balancing, power monitoring, advanced metering infrastructure, circuit breaker panels and smart meters. The Sidewinder products differ from traditional current sense transformers because they do not contain a magnetic core. This makes them more accurate and linear, lighter, easier to assemble, less expensive and offers flexibility of design to suit wide ranging applications.

Glenn Roemer, Field Application Engineer, Pulse Electronics, comments: "Through the use of recognised industry testing standards, Pulse has verified Sidewinder designs to be suitable for use in mission critical end products that require maximum uptime and reliability. The excessive and constant stresses applied in a controlled test accelerate the ageing and failure mechanism of the component under test. We are very pleased that the test results support previous life-stress modeling data."
