Description: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, andstore the accumulated energy data before power off. Designed with one key reset button, you can reset energy data bysimply pressing one button.The TTL serial port can communicate, read and set parameterswith a variety of terminals through a USB adapter.Features:This is a electric monitoring test module which can be used to test power, energy, voltage and current.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.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.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.Itdisplays through PC or other terminals, and you can download the software for PC. For other terminals, itneedto be programmed by yourself.Specifications:Working Voltage: 80~260VACTest Voltage: 80~260VACRated Power: 100A/22000WWorking Frequency: 45-65HzMeasurement Accuracy: 1.0Board Size: 7.3 x 3 x 2.3cm / 2.87 x 1.18 x 0.9"Display Format:1.

Voltage Test Range: 80~260VACDisplay Format is 110.0 ~ 220.04. Current Test Range: 0~100ADisplay Format is 00.00 ~ 99.99Function:1. Voltage(V), current(A), average power(kW), energy(kWh) measurement.2. Energy reset by pressing one button.3. Store data when power off(store the accumulated energy data before power off).4. PC display function(display voltage, current, average power, energy).5.Serial port communication function(TTL serial port can communicate, read and set parameterswith a variety of terminals through a USB adapter).Display Interface:It displays through PC or other terminals(need to be programmed by yourself), the following are brief description of each parameter display:1. Voltage(V) DisplayMeasure and display the voltage of electric power grid.2. Current(A) DisplayMeasure 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.3. Energy(kWh) DisplayMeasure 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.4. Power(kW) DisplayMeasure 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 requirementof testing power within 1W, it is not recommended.Serial Port CommunicationThis 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.
