1. Current transformers accurately sense and measure current flow in power supply circuits in a non-invasive way.
2. Ideally, they shunt a very small sample of the current to measure while dissipating minimal energy. The sensed current information is typically used to prevent overcurrent conditions and to monitor and control circuits in power supplies and other powered applications. Current sensors are frequently used to measure and control the load current in power supplies, safety circuits and a variety of control circuits.
3. In applications where controlling the current is required, such as in power supplies, accurately sensing the magnitude of the current is a fundamental requirement. Coilcraft manufactures wire-through-hole current sensors and SM current sense transformers for measuring current at frequencies from 50/60 Hz to greater than 1 MHz.
