KPM73 Multi function Panel Meter

Features of multi function panel meter

• Measure more than thirty different types of fundamental electricity, including phase/line voltage, three-phase current, zero sequence voltage, zero sequence current, apparent power, active power, reactive power, power factor, and frequency.
• Determine the amount of reactive energy consumed each month with precision by measuring and displaying the average power factor of the previous three months.
• Multi-rate statistics and power statistics for the class 0.5S 4 quadrant
• Compile demand data and note the highest and lowest values. Working hours and statistics about load times
• The function for recording time can capture 100 events.
• Support computation of the current K factor, imbalance rate, total harmonic distortion rate, and up to the 51st harmonic.
• Modbus-RTU protocol, standard 1-way Rs485 communication interface, and optional Profibus-DP connection module.
• Four-way passive digital input is optional. 4-way relay output option
• One-way 4–20 mA analog output option
• Passive optical coupler collector with one road and active pulse output Optional 1-way PT100 temperature input with voltage and current sampling at 256 points per cycle to guarantee measurement accuracy
• To get a good visual effect in a bright light and large viewing angle environment, use the FSTN large screen LCD with bright LED backlight uniform display.

Application of multi function panel meter

The applications of the multi function panel meter are listed in the following:

• Measure, and monitor power distribution system parameters
• Collect energy consumption data that cost center analysis needs
• Limit monitor alarm (such as over-voltage, and power consumption)
• Power quality analysis
• DC/Green building, or DC
