Description: _x000D_ This is a electric monitoring test module which can be used to test power, energy, voltage and current then displayed on a PC or other terminals. It can store data when power off, and store the accumulated energy data before power off. Designed with one key reset button, you can reset energy data by simply pressing one button. The TTL serial port can communicate, read and set parameters with a variety of terminals through a USB adapter. _x000D_ _x000D_ _x000D_ Features: _x000D_ This is a electric monitoring test module which can be used to test power, energy, voltage and current. _x000D_ The connection of this module is divided into 2 parts: voltage, current input connection and serial port communication, and you can use different TTL adapters to make it communicate with various terminals. _x000D_ The test module is design to test high power equipment and you can observe the accumulative process intuitively for the low-power(within 100W)load test. _x000D_ There is a button on module for energy reset, simply press and hold the button for 5 seconds and release, then press the button again to finish energy reset. _x000D_ It displays through PC or other terminals, and you can download the software for PC. For other terminals, it need to be programmed by yourself. _x000D_ _x000D_ _x000D_ Specifications: _x000D_ Working Voltage: 80~260VAC _x000D_ Test Voltage: 80~260VAC _x000D_ Rated Power: 100A/22000W _x000D_ Working Frequency: 45-65Hz _x000D_ Measurement Accuracy: 1.0 _x000D_ Board Size: 7.3 x 3 x 2.3cm / 2.87 x 1.18 x 0.9"_x000D_ _x000D_ _x000D_ _x000D_ Display Format: _x000D_ 1.

Voltage(V), current(A), average power(kW), energy(kWh) measurement. _x000D_ 2. Energy reset by pressing one button. _x000D_ 3. Store data when power off(store the accumulated energy data before power off). _x000D_ 4. PC display function(display voltage, current, average power, energy). _x000D_ 5. Serial port communication function(TTL serial port can communicate, read and set parameters with a variety of terminals through a USB adapter). _x000D_ _x000D_ _x000D_ Display Interface: _x000D_ It displays through PC or other terminals(need to be programmed by yourself), the following are brief description of each parameter display: _x000D_ 1. Voltage(V) Display _x000D_ Measure and display the voltage of electric power grid. _x000D_ 2. Current(A) Display _x000D_ Measure and display the current of load (device). The current test value is from the beginning of 10mA, and this module is designed to test high power equipment, if you need the current testing accuracy in mA level, it is not be recommended. _x000D_ 3. Energy(kWh) Display _x000D_ Measure and display the accumulative power consumption. The minimum unit of the energy metering is 0.001kWh, which means it begins to accumulate from 1Wh. You can observe the accumulative process intuitively for the low-power(within 100W)load test. _x000D_ 4. Power(kW) Display _x000D_ Measure and display the load power. The power test value is from the beginning of 0.001kW, which means it begins to test from 1W, and this module is designed to test high power equipment, if you have the requirement of testing power within 1W, it is not recommended. _x000D_ _x000D_ _x000D_ Serial Port Communication _x000D_ This module is design with TTL serial port data communication interface, you can read and set the relevant parameters via serial port. If it need to communicate with a device which has USB or RS232 (such as computer), a TTL adapter is required.
