Introduction
Introduction
Meter overview
The PM1130H / EM6438H series meters are dual source meters that offer comprehensive 3-phase electrical instrumentation and load management facilities in a compact and rugged package.
The PM1130H / EM6438H meters offer value for the demanding needs of your energy monitoring and cost management applications. Meters in the series range comply with Class 0.5 (PM1130H & EM6438H) and Class 1.0(EM6438H) accuracy standards and feature high quality, reliability and affordability in a compact and easy to install format.
Meter features
The PM1130H / EM6438H meter supports many features, a few of the features are listed below:
· LED display screen: Intuitive self-guided navigation using four buttons LED display, with three lines of concurrent values, and load bar that indicates current loading
· Energy accounting and balancing
· Relay (PM1130H only), alternate source, and RS-485
· THD% for voltage and current, per-phase
· Active, reactive, and apparent energy readings
· Cyber security: The meter enables disabling the RS-485 port through front panel keys against unauthorized access. This feature can also be used for toggling between the RTU devices in case of limited availability of nodes in software system
· Measurement of True PF
You can use the meter as a stand-alone device, but its extensive capabilities are fully realized when used as part of an energy management system.
For applications, feature details, and the most current and complete specifications of the PM1130H / EM6438H meters, see the technical datasheet at www.se.com.
Application
Your device can be used for dual source accounting applications that involve two energy registers, for example Utility vs Genset, Utility vs Solar, Utility vs Wind, or a combination of any two-power source.
Your device can also be used in installations that require split energy monitoring for two conditions, for example, running and idle. You can form a relay to control the load in event of abnormalities such as excessive power consumption or electric faults.
The meters can be used for secondary billing application in large commercial complexes or buildings as tenant meters in custom panels, switch boards, switchgear, Gen-set panels, non-renewable energy panels, and OEM panel boards.
Prepaid metering
A prepaid metering system enables customers to pay money to the facility management in advance for a fixed energy value. Prepaid metering is advantageous to both, the facility management and customers. While the facility
10
QGH1336303-05
Introduction
EasyLogicTMPM1130H/EM6438H
management can eliminate meter readings and get advanced payments, the customers can be freed of penalty through already stored energy consumption as against unit consumption.
The meter supports prepaid energy metering. Customers can add on energy credits to the balance register of the meter through communication only. The meter starts deducting the units based on energy consumption.
The customer can set a minimum value for energy credits consumption, beyond which the meter raises an alarm. The meter indicates the alarm through front panel LED, by blinking the top most LED on the load bar. In situations where the energy credits get exhausted, the meter switches on the relay. Beyond which, if the energy consumption continues, the meter keeps accumulating negative balance. When the customers recharge the next time, the negative accumulated energy will get deducted and only the balance energy will get credited for use.
The facility management can configure any one of the power source, that is Utility, Alternate Source, or Total (Utility + Alternate Source) based on the billing system.
Cost management
Your device can be used in various cost management applications.
Some of the applications are as mentioned below:
· Measurement of basic electrical parameters in control panels, power distribution boards, OEM’s, Building management systems, and panel instrumentation
· Aggregate energy consumption and cost allocation based on consumption from Utility vs Genset, or between any two power sources, per area, per shift, and per time within the same facility
Network management
Your device can be used in various network management applications.
Some of the applications are as mentioned below: · Power quality analysis (THD %) · Demand measurement · Measurement of power factor · Phase angle between the voltage and current · % unbalance among voltage and current · Modbus RTU protocol RS-485 port for integration with energy management system

Terminal covers
The voltage and current terminal covers help prevent tampering with the meter’s voltage and current measurement inputs.
The terminal covers enclose the terminals, the conductor fixing screws and a length of the external conductors and their insulation. These covers are secured by tamper-resistant meter seals. Ensure you push the cover upwards till you hear a click to make the cover stand.

Direct connect voltage limitsMeasuring voltage limit
You can connect the meter’s voltage inputs directly to the phase voltage lines of the power system if the power system’s line-to-line or line-to-neutral voltages do not exceed the meter’s direct connect maximum voltage limits.
The meter’s voltage measurement inputs are rated by the manufacturer for up to 277 V L-N / 480 V L-L. However, the maximum voltage allowed for direct connection may be lower, depending on the local electrical codes and regulations. As per installation category III the maximum voltage on the meter voltage measurement inputs should not exceed 277 V L-N / 480 V L-L.
If your system voltage is greater than the specified direct connect maximum voltage, you must use VTs (voltage transformers) to step down the voltages.

Balanced system considerations
In situations where you are monitoring a balanced 3-phase load, you may choose to connect only one or two CTs on the phase(s) you want to measure, and then configure the meter so it calculates the current on the unconnected current input(s).
NOTE: For a balanced 4-wire Wye system, the meter’s calculations assume that there is no current flowing through the neutral conductor.
Balanced 3-phase Wye system with 2 CTs
The current for the unconnected current input is calculated so that the vector sum for all three phases equal zero.
Balanced 3-phase Wye or Delta system with 1CT
The currents for the unconnected current inputs are calculated so that their magnitude and phase angle are identical and equally distributed, and the vector sum for all three phase currents equal zero.
NOTE: You must always use 3 CTs for 3-phase 4-wire center-tapped Delta or center-tapped open Delta systems.
