This module is mainly used for measuring AC voltage, current, active power and active energy, the module is without display function, the data is read through the TTL interface.
Feature:
1. Support for overload alarm function, exceeding power alarm threshold power flashing alarm.
2. Support for power alarm threshold preset function, you can set the power alarm threshold by yourself.
3. Support for electrical parameter measurement function, measuring voltage, current, active power and energy.
4. Support for energy button clear function and support power-down data saving function (save power before power-down).
5. Support for highlight red LED display function, display voltage, current, active power and power.
6. Support for serial communication function, with TTL serial interface, can communicate with various terminals through the adapter board, read and set parameters.
7. The display consists of four four-digit bright red digital tubes for displaying voltage, current, power, and energy parameters.
1. Working voltage: 80 ~ 260VAC
2. Test voltage: 80 ~ 260VAC
3. Rated power: 100A/22000W
4. Operating frequency: 45-65Hz
5. Measurement accuracy: 1.0 grade
Function
1. Ectrical parameter measurement function (voltage, current, active power, energy).
2. Overload alarm function (over power alarm threshold the power flash).
3. Power alarm threshold preset function ( can set power alarm threshold).
4. The reset function of energy key.
5. Store data when power off (store the accumulated energy before power off).
6. Bright red digital display function (display voltage, current, active power, energy).
7. Serial communication function (with TTL serial interface itself, can communicate with a variety of terminal through the pin board, read and set the parameters).

1000 ~ 9999kWh and above, the display format is 1000 ~ 9999.
3. Voltage: Test Range: 80 ~ 260VAC
Display Format is 110.0 ~ 220.0.
4. Current: Test Range: 0 ~ 100A
Display Format is 00.00 ~ 99.99.
III. Key
There is a key on the panel, it can be used to reset energy.
The method of reset energy: Long press the key for 5 seconds until the digital on energy display window flicker, then release the key. Short press the key again, then the energy data is cleared and quit the flickering state, now the reset operation is completed; if long press for 5 seconds again until no longer flicker, it means exit the reset state
Illustration of the communication
1. Connect hard wire according to the wiring diagram in figure 1 and 2.
2. After connect the wire, please choose the communication port, this module’s upper computer software support communication port: COM2\COM3\COM4, you can check through device manager, if it is not the above communication port, you should amend it through port.
Precautions
1. This module is suitable for indoor, please do not use outdoor.
2. Applied load should not exceed the rated power.
3. Wiring order can’t be wrong.
