ENTES EPR-04S Power Meter User Manual
Below you will find brief information for Power Meter EPR-04S. This power meter is a 3-phase powermeter and energymeter that can measure active power, active energy, reactive power, reactive energy, apparent power, and power factor. It has a MODBUS serial interface and can be connected to a PC for data analysis. The EPR-04S also measures maximum demand, demand, maximum and minimum values of power, all of which can be accessed through the device's interface or via MODBUS communication. It can connect up to 247 devices using a repeater.

EPR-04S-31 TR B A GND TR B EPR-04S-2 A GND EPR-04S displays the energy and power values by multiplying voltage and current ratios by values read from input. So, the displayed values are the real values of system. Energy Pulse Outputs EPR-04S has 2 Energy Pulse Outputs; Pul1, Pul2. Pul1 (Reactive Energy Pulse Output): A 400msec. pulse output is given, if measured energymeter value increases 1 KVArh. Pul1 is used for Reactive Inductive energy values. Pul2 (Active Energy Pulse Output): A 400msec. pulse output is given, if measured energy meter value increases 1KWh. Pul2 is used for both (Active Import) and (Active Export) energy values.

Min. and Max. values are defined for Active Power(W),reactive power(VAr) and apparent power(VA). Demand values are defined for total active power(W),total reactive power(VAr) and total apparent power(VA). If measured instant value is smaller than min. value which was stored before, it is stored as new min. value. If measured instant value is greater than max. value which was stored before, it is stored as new max. value. Demand value is the smallest value of the measured values in demand time. If the smallest value of the measured values (for example 15 minute) in demand time is greater than the demand value which was stored before, it is stored as new demand value. If one of defined parameters is displayed when deman button is pressed , min.,max or demand values are displayed. When an undefined parameter is displayed if demand button is pressed, instant value is continued to display. For example when power factor is displayed instant values are continued to display because min., max. and demand values are undefined.

Frequently Answers and Questions
What is the purpose of the EPR-04S Power Meter?
The EPR-04S power meter is a 3-phase digital powermeter and energymeter that measures a wide range of electrical parameters, including active power, active energy, reactive power, reactive energy, apparent power, and power factor. It also provides information about maximum demand, demand, and maximum and minimum values of power. These measurements are crucial for monitoring and managing electrical systems efficiently.
Can I connect multiple EPR-04S devices to my system?
Yes, you can connect up to 247 EPR-04S devices to your system using a repeater. This allows you to monitor a larger network of power sources and loads.
What is the MODBUS serial interface used for?
The MODBUS serial interface enables communication between the EPR-04S power meter and a PC or other compatible devices. This allows you to read and manage all the measured parameters of the device, including transformer ratios, demand values, energy values, and other settings. By connecting to a PC, you can analyze the data and generate reports for monitoring and control purposes.
How do I set the transformer ratios for the EPR-04S?
The EPR-04S allows you to set the transformer ratios for both voltage and current transformers. This ensures that the device captures accurate measurements of voltage and current in your electrical system. You can set these ratios using the device's interface, a PC, or a dedicated software such as the MPR-SW-1/SW-2 software.
What is the meaning of maximum demand and demand values?
Maximum demand represents the maximum value of average power values measured during the demand time, which you can set between 1 and 60 minutes. Demand refers to the average power value measured during the specified demand time. These values are critical for understanding peak loads and ensuring that your electrical system can handle them efficiently.
