Description
Overview: 1.We provide the software to connect it with the PC. If you want to connect it with other terminal device such as PLC, and so on, please prepare the fitable cable and write the program by yourself.2. This document describes the specification of the PZEM-004T AC communication module, the module is mainly used for measuring AC voltage, current, active power, frequency, power factor and active energy, the module is without display function, the data is read through the TTL interface. PZEM-004T-10A: Measuring Range 10A (Built-in Shunt)PZEM-004T-100A: Measuring Range 100A (external transformer) If you need the software, please download it via this link: http://www.mediafire.com/file/lk5wukg2v5n5iry/004T_software%252Bdriver%252Buser_manual.zip/file Specifications: Working voltage: 80 ~ 260VACTest voltage: 80 ~ 260VACRated power: 100A/22000WOperating frequency: 45-65HzMeasurement accuracy: 1.0 grade Function: Voltage1.1.1 Measuring range:80 - 260V1.1.2 Resolution: 0.1V1.1.3 Measurement accuracy: 0.5%1.2 Current1.2.1 Measuring range: 0 -10A(PZEM-004T-10A); 0-100A(PZEM-004T-100A)1.2.2 Starting measure current: 0.01A(PZEM-004T-10A); 0.02A(PZEM-004T-100A)1.2.3 Resolution: 0.001A1.2.4 Measurement accuracy: 0.5%1.3 Active power1.3.1 Measuring range: 0-2.3kW(PZEM-004T-10A); 0-23kW(PZEM-004T-100A)1.3.2 Starting measure power: 0.4W1.3.3 Resolution: 0.1W1.3.4 Display format:<1000W, it display one decimal, such as: 999.9W?1000W, it display only integer, such as: 1000W1.3.5 Measurement accuracy: 0.5%1.4 Power factor1.4.1 Measuring range: 0.00-1.001.4.2 Resolution: 0.011.4.3 Measurement accuracy: 1%1.5 Frequency1.5.1 Measuring range: 45Hz-65Hz1.5.2 Resolution: 0.1Hz1.5.3 Measurement accuracy: 0.5%1.6 Active energy1.6.1 Measuring range: 0-9999.99kWh1.6.2 Resolution: 1Wh1.6.3 Measurement accuracy: 0.5%1.6.4 Display format:
