Features:
- 1. Mutual inductance current monitoring, high current detection accuracy, stable performance, safe isolation of input and output.
- 2. The measured current AC: 0-10A / 20A / 50A, 0-100A / 150A / 200A can be selected.
- 3. Output signal DC: 0-5V / 0-10V /4-20mA three forms are available.
- 4. Installation and using are easy and convenient, there is no need to connect the dc series into the circuit during measurement.
- 5. Through-heart structure design, isolation withstand voltage up to 2000V AC.
- 6. Magnetic hysteresis less than 1%, can be used in strong magnetic field conditions.
- 7. The outer casing is made of self-extinguishing material, safe and durable.
- 8. It is used for AC current monitoring, detection, current overload protection, and is also used as an electronic switch for automatic control systems.
- 9. It is suitable for various applications requiring current and voltage conversion.
- 10. It has the characteristics of strong overload ability, high precision, high isolation, high security, low power consumption and strong anti-interference ability.
- The SZT20-CH-420E AC current transducer provides real-time isolated measurement of AC current in the grid or circuit and converts it to a 0-5V/0-10V or 4-20mA DC current output signal. It can be mated with various AD and constitute various digital centralized acquisition systems. Or output to the PLC to form an automatic control system, or to match the traditional analog and digital indicating instruments, display the measured value.
Package list:
- 1 * AC Current Transducer
Working principle:
- 1. Based on electromagnetic induction, inductive current will be generated when the current in the circuit changes. Transform large current into standard small current through transformer,
- 2. Through relevant signal processing circuit and output control circuit, the dc current signal of 0-5/10V or 4-20mA can be output and transmitted to the next level system.

no instructions, but very easy to setup. your AC Leg goes through the transducer and connect 24 volts dc to the lugs. to measure 4-20mA connect either your meter in series with the negative or connect the negative directly to your 4-20mA device(as long as the device is utilizing the same 24vdc +).

Bom dia, comprei esses transdutores em Agosto de 2023.Foram instalados em Novembro de 2023. Só que eles não estão funcionando desde o dia 07/03/2023.Os 2 que comprei abriram.Estou sem assistência, o prazo de garantia encerou em Setembro de 2023, mesmo assim o tempo muito curto de vida útil do produto.
