FEATURES
• Package : mod. DIL-14
• A magnetic sensor chip (employing
the
magnetoresistive effect of thin film permalloy)
measures the magnetic field generated by an
internal current-carrying conductor
• measurable direct or alternating current I up to
M
20A
• supply voltage 12 V
• no auxiliary field H required
X
• it’s possible to overload the conductor (between
pin’s 8,9,10 and 11,12,13) with 300A for 10 ms
at T
= 20 °C
