52120A/COIL 3 KA 25-Turn Coil

Number of Turns ................................................... 25
Minimum internal jaw dimension to clear wires 26 mm (width) x 36 mm (length)
Maximum Input Current ........................................ 120 A continuous with built-in 12 V fan on
Maximum Voltage ................................................. 4.5 V rms

0 A to 100 A
0 A to 120 A 10 Hz to 65 Hz
0 A to 120 A 65 Hz to 300 Hz
0 A to 40 A 300 Hz to 1 kHz
0 A to 12 A 1 kHz to 3 kHz
0 A to 3 A 3 kHz to 6 kHz
0 A to 1 A 6 kHz to 10 kHz
Notes:
1. The inductance and mutual inductance of the 25 turn coil and clamp that is measured causes a frequency dependent compliance
voltage across the coil. The length and configuration of the cables that connect the current to the coil also have an effect.
Maximum input current is 120 A input at approximately 100 Hz. Maximum current input decreases to approximately 0.8 A at
10 kHz.
2. Includes coil/clamp interaction.
