Description: This is an electric monitoring test module with a split-core current transformer. The module can be used to test power, energy, voltage as well as current, and then display on a PC or other terminals. Designed with one for key reset button, you can reset energy data by simply pressing one button. Moreover, it can store data when power off, and store the accumulated energy data before power off, so it is very convenient to use it. It can be widely used with power distribution box, distribution cabinet, voltage regulators, teaching aids and household small distribution box. Features: AC 80-260V voltage test range, 80-260V working voltage, maximum current can reach to 100A Electrical parameter measurement function including voltage, current, active power and energy measurement Designed to test high power equipment and you can observe the accumulative process intuitively for the low-power(within 100W)load test Equipped with TTL serial data communication interface, you can read and set the relevant parameters via the serial port The for key on the panel can be used to reset energy, convenient to users Note: 1. This is an indoor module and can not be used outdoors. 2. Load can be over rated power. 3. Wiring can not be wrong. Specifications: Working Voltage: 80~260V AC Test Voltage: 80~260V AC Rated Power: 100A/22000W Working Frequency: 45-65Hz Measurement Accuracy: 1.0% Board Size: 7.3x3cm/2.87x1.18" Current Transformer Size: 3.1x2.9x4.7cm/1.22x1.14x1.85" Wire Length: 20cm/7.87" Quantity: 1 Set Note: Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
