E-T-A Circuit Breakers launches over current detectors

E-T-A Circuit Breakers has launched a new line of over current detectors. The TD and 9001 Hall effect current detectors protect power semiconductors in power electronic circuits by signaling when current in the circuit has exceeded the nominal detector trip point. Units are designed to be mounted directly to a printed circuit board and, like Hall effect current sensors, provide isolation between the sensed current and the output.

E-T-A’s over current detectors are available in a range of set detector trip points and are integrated with a digital output factory programmed to go low when the trip point is exceeded. Both have a response time of 1 √Ǭµs (typical) – allowing time for the system control circuit to protect the power circuit. The TD and 9001 operate over a temperature range of -40 to +125¬∞ C and, because the devices are Hall effect based, have negligible levels of power dissipation, even in high frequency switching circuits.

The TD and 9001 over current detectors are designed to protect power semiconductors in power electronic circuits. Typical applications include, but are not limited to: welding equipment, servo drives, treadmills, automotive power conversion, power supplies, home audio, and MRI equipment.
