Energy Meters By xcluma

• 1. Accuracy: 1% 2. Range: AC voltage: AC 80-300V AC current: AC 0-99.99A, minimum resolution is 0.01A.Display 100.0A when the current is over 100A Active power: 0-45000W. resolution is 0.1W (< 0-9999.9W ), otherwise Minimum resolution is 1W.
• Electric energy: 0-9999999Kwh 0-9999.999kwh minimum resolution is 0.001kwh 10000.00-99999.99kwh minimum resolution is 0.01kwh 100000.0-999999.9kwh minimum resolution is 0.1kwh The rest minimum resolution is 1Kwh. 3. Speed: 2 times per second 4. Size: 79x43x48mm 5. Installation Size: 76*39mm 6. Auto-saving: When power off, the electric energy will be saved. The saved electric energy will be accumulated continued when the meter power-on next time. "
• "1. The voltage input will connect to green terminal and the current transformer will connect to blue terminal. block can not be connected incorrectly, otherwise the instrument will be damaged! ! ! 2. This instrument is only suitable for pure AC 50-60HZ mains power supply, can not be used for square wave, inverter output and modified wave circuit measurement, otherwise the instrument will be damaged! ! !
• 3. During the process of installing the instrument, remember not to squeeze the LCD screen of the instrument, otherwise garbled/broken code will occur! !! 4. Many buyers responded: How is the data I tested wrong, voltage * current = power, the actual test power is less than the voltage * current, why?
• A: there are three types of power: active power (P for / unit W), reactive power (Q for / unit Var), and apparent power (S for / Unit VA). Here only the active power,The calculation formula of active power is: P=U*I*cos?, cos? represents power factor, and the power factor of pure resistive load is generally close to 1, and the inductive and capacitive load load power factor is Between 0-1; the power factor of each appliance is different.

• 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
• 1. Electrical parameter measurement function (voltage, current, active power, energy) 2. Overload alarm function (over power alarm threshold, backlight and power flashing to alarm). 3. Power alarm threshold preset function (can set power alarm threshold). 4. The reset function of energy key. 5. Store data when power off. 6. Large-screen LCD (display voltage, current, active power, energy at the same time) 7. Backlight function.

• Model: PZEM-004T 1. electrical parameter measurement function (voltage, current, active power). 2. The power button clear function. 3. Power-down data storage function (cumulative power down before saving). 4. PC PC display function (display voltage, current, active power). 5. The serial communication function (comes with TTL serial interface, via various terminals communicate with the adapter plate, read, and set the parameters).
• 1. Power: meas range 0 ~ 22kW 0 ~ 10kW within display format of 0.000 to 9.999; Within 10 ~ 22kW display format 10.00 ~ 22.00. 2. Power: measrange 0 ~ 9999kWh 0 ~ 10kWh within display format of 0.000 to 9.999; 10 ~ 100kWh within display format of 10.00 to 99.99; 100 ~ 1000kWh within display format of 100.0 to 999.9; 1000 ~ 9999kWh and above display format from 1000 to 9999. 3. Voltage Range 80 ~ 260VAC Display Format 110.0 ~ 220.0. 4. Current meas range 0 ~ 100A Display Format 00.00 to 99.99.
• Electricity clear method: Press ZERO key five seconds, then release the button! Press again to clear the key, the data is cleared and exit charge cleared, cleared so far completed.>>Serial Communication if you want a device with a USB or RS232 (such as computers) to communicate, then you need to be equipped with different TTL adapter hardware board (USB communication needs with TTL to USB adapter plate;
• 1. Connect the hardware according to the wiring diagram. 2. Connect the line after a good first select the communication port of the PC software module supports communication port COM2 COM3 COM4, through the Device Manager to view, if not more than a few ports you need to modify the port over. E. Considerations 1. This module is suitable for indoor, not outdoor use. 2. the applied load should not exceed the rated power. 3. The wiring can not be wrong.
