About this item

  • Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can convert high voltage into low voltage, and large current into small current for measurement or protection of the system.
  • Convert high voltage or large current into standard low voltage (100V) or standard low current (5A or 1A, both refer to rated values) in proportion to achieve standardization and miniaturization of measuring instruments, protection equipment, and automatic control equipment.
  • Rated input current: 1.5A; Rated output current: 0.5mA; Accuracy level: 0.5; Transformation ratio: 3000:1; Installation method: open type
  • Linear range: 0-70A (20 Ω); Working temperature: - 40 ℃~+75 ℃; Operating frequency: 50HZ/60HZ; Relative humidity ≤ 95%
  • Dielectric strength: The power frequency voltage between the primary and secondary windings is 2.5KV/min, without breakdown or arcing, and the leakage current is<1mA; Insulation resistance: 1000M Ω/500Vdc between primary and secondary windings

As far as CTs go, this is a very low current model.If you're looking for CTs, I don't need to go into any real theory of operation.The accuracy claims are pretty close.The real beef that I have with this is the build and durability around the split. I think if they did a little better job here, the accuracy would be a lot better.If you're just looking to get into the ball park of the measuring current for your project and you don't want to spend a ton of cash, these are OK.
