It features mutual inductance current monitoring with exceptional accuracy, a wide selection of measurable currents, and multiple output signal formats. Its user-friendly design ensures easy installation without the need for complex wiring, while its robust isolation withstand voltage guarantees safety and reliability. ## Description 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.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.Specification:Product Name: AC Current TransmitterModel: SZT20-CH-420EPower supply:Voltage output type, self-power supply does not require external current.Current output type requires ex ## Features - Mutual inductance current monitoring, high current detection accuracy, stable performance, safe isolation of input and output. - The measured current AC: 0-10A / 20A / 50A, 0-100A / 150A / 200A 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. ## Images ![AC Current Sensor, Current Transmitter Stable Current Transformer High for Automatic Control Systems for Electrical - Image 1](https://m.media-amazon.com/images/I/519UsPMsjkL.jpg) ![AC Current Sensor, Current Transmitter Stable Current Transformer High for Automatic Control Systems for Electrical - Image 2](https://m.media-amazon.com/images/I/51HBnTRWWPL.jpg) ![AC Current Sensor, Current Transmitter Stable Current Transformer High for Automatic Control Systems for Electrical - Image 3](https://m.media-amazon.com/images/I/61Ju7Hxt6xL.jpg) ![AC Current Sensor, Current Transmitter Stable Current Transformer High for Automatic Control Systems for Electrical - Image 4](https://m.media-amazon.com/images/I/61NotEYF8dL.jpg) ![AC Current Sensor, Current Transmitter Stable Current Transformer High for Automatic Control Systems for Electrical - Image 5](https://m.media-amazon.com/images/I/51KWrkdoDJL.jpg) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/403960736-ac-current-sensor-current-transmitter-stable-current-transformer-high-automatic](https://www.desertcart.fi/products/403960736-ac-current-sensor-current-transmitter-stable-current-transformer-high-automatic) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-05-25*
