52120A/COIL 6 KA 50-Turn Coil

Number of Turns ................................................... 50
Minimum Flexible Probe Length .......................... 500 mm
Maximum Input Current ........................................ 120 A continuous with built-in 12 V fan on
Maximum Voltage ................................................. 4.5 V rms

Notes:
1. The inductance and mutual inductance of the 50 turn coil causes a frequency dependent compliance voltage across the coil.
Maximum frequency for 120 A input current is approximately 600 Hz. Maximum current input decreases to approximately 13 A at
10 kHz.
2. Includes coil/probe interaction.
The specifications for these coils are at 99 % confidence level and are the combined
specification of the coil and a 52120A. If the coils are used with other current
sources the calibration specification of the coils alone is 0.65 % (99 % confidence
level) from 0 Hz to 10 kHz.
