TD1020 Current Coil

1. Summary of TD1020 Current Coil

TD1020 is a series of current coils，adopting the principle of equivalent ampere turns. It is applied for calibrating clamp Ammeters combined with AC\DC current source.

2. Features of TD1020 Current Coil

Equivalent current output: 1000 A / 2000 A
Max current input: 22 A_rms / 44 A_rms
Coil ampere-turn specification: 50 turns/100 turns
DC accuracy: 0.3%
AC accuracy: 0.3%@50Hz，0.5%@400Hz
Frequency: DC，45 Hz ~ 400 Hz

3. Application of TD1020 Current Coil

☆ Calibrate clamp ammeter

TD1020 Current Coil Calibrate clamp ammeter

TD1020 can be used with AC and DC standard sources to achieve equivalent current output of up to 1000 At / 2000 At.
Used to calibrate clamp ammeters with lower accuracy of class 1 and below.
