Review: Like ! - A + + + Seller, Good Price, Fast Shipping, Will Buy From Again !
Review: Working great! - I've used this for three months in a power monitoring application on an off grid house. It monitors Line 2 of the 240. and I have a much more expensive LEM on line 1. It works exactly like the fancier version for much le$$. I would buy it again.

## Features

- Mutual inductance current monitoring, high current detection accuracy, stable performance, safe isolation of input and output.Magnetic hysteresis less than 1%, can be used in strong magnetic field conditions.
- The measured current AC: 0-10A / 20A / 50A can be selected.Output signal DC: 0-5V / 0-10V /4-20mA three forms are available.
- Installation and using are easy and convenient, there is no need to connect the dc series into the circuit during measurement.Through-heart structure design, isolation withstand voltage up to 2000V AC.
- The outer casing is made of self-extinguishing material, safe and durable.It is used for AC current monitoring, detection, current overload protection, and is also used as an electronic switch for automatic control systems.
- It is suitable for various applications requiring current and voltage conversion.It has the characteristics of strong overload ability, high precision, high isolation, high security, low power consumption and strong anti-interference ability.
