TD1020 Current Coil
TD1020 Current Coil
Advanced Multiproduct or Multifunction Calibrator
The TUNKIA TD1020 is a professional series of precision current coils designed using the principle of equivalent ampere-turns. When paired with an AC/DC current source, the TD1020 enables accurate calibration of clamp ammeters across different ranges and accuracy levels. With high stability, reliable performance, and multiple turn configurations, it offers a dependable solution for laboratories, calibration facilities, and industrial metrology applications.
The TD1020 series provides models with up to 100 turns and supports current inputs up to 44 Arms. Designed to maintain excellent performance across DC and wide AC frequency ranges, the TD1020 ensures accurate and repeatable measurements. For best results, the clamp meter jaws should be positioned at the coil’s center to avoid additional measurement errors.
| Model | Turns (Middle) | Turns (Side) | Max Current Input | Continuous Output Time | Frequency | Accuracy |
|---|---|---|---|---|---|---|
| TD1020-50T-20A | 50 | 25 | 22 Arms | <11 A continuous; >11 A ≤ 30 minutes | DC, 45 Hz ~ 400 Hz | DC: ±0.3% AC: ±0.3% @ 50 Hz, ±0.5% @ 400 Hz |
| TD1020-50T-40A | 50 | 25 | 44 Arms | <22 A continuous; >22 A ≤ 30 minutes | DC, 45 Hz ~ 400 Hz | DC: ±0.3% AC: ±0.3% @ 50 Hz, ±0.5% @ 400 Hz |
| TD1020-100T-20A | 100 | 50 | 22 Arms | <11 A continuous; >11 A ≤ 30 minutes | DC, 45 Hz ~ 65 Hz | DC: ±0.3% AC: ±0.3% @ 50 Hz, ±0.5% @ 400 Hz |
Note: During calibration, ensure the clamp meter jaws are placed at the center of the TD1020 current column to avoid additional measurement errors.
