Feature: 1. Mutual inductance current monitoring, with high current detection accuracy and stable performance. 2. The measured current has AC 0‑10A/20A/50A; 0‑100A/150A/200A can be selected. 3. The output signal has three forms of DC0‑5V/0‑10V/4‑20mA to choose from. 4. With strong overload capacity, high accuracy, high isolation, high safety and other functions. 5. Through core structure design, isolation withstand voltage up to 2000VAC, hysteresis lower than 1%, can be used under strong magnetic field conditions. 6. The shell is made of self‑extinguishing material ABS, easy to install and use. Specification: Item Type: AC Current TransmitterMaterial: Plastic Model: SZT15-SH-420E External Power Supply: 24VDC (±10%) Input Through-Core Current: 0-50A AC Output Type (DC): Current Output Type: 4-20mA Minimum Switch Conduction: 1.5±0.2A Maximum Overload of Through-Core Current: 200% (the through-core current cannot exceed 200% of the rated value) Accuracy: 10% Power Consumption: ≤1W Maximum Leakage Current: ≤1mA Hysteresis: ≤1% Response Time: ≤200ms Working Temperature: -30~70℃ Humidity: 0-95% (no condensation) Square Diameter: Approx. 20 x 20mm / 0.8 x 0.8in Scenario Product Description: The SZT15/SZT20 series of AC current transmitters can isolate and measure the AC current in the power grid or circuit in real time, and transform it into a 0-5V/0-10V or 4-20mA DC output signal, which can be matched with various ADs. It can be connected to form various digital centralized acquisition systems, or output to PLC to form an automatic control system, or be connected with traditional analog or digital indicating instruments to display the measured value. SZT15 series can sense through-core current AC: 0-10/20/50A; SZT1020 series can sense through-core current AC: 0-100/150/200A, select the appropriate through the jumper cap on the transmitter Through the heart current..
