1.1 Overview
1.1.1 Construction Profile
Figure 1.1.1: APL SEM 3P V2 Three-phase Keypad Prepayment Energy Meter
1.1.2 Major Application
APL SEM 3P V2 Three-phase Keypad Prepayment Energy Meter takes digital medium as
information exchange media. It is an active electric energy meter in which users load in pre-
purchased energy, and it takes energy as its billing. The meter includes measurement unit,
real-time clock unit, infrared communication, load switch, GPRS communication module and
other auxiliary equipment.
1.1.3 Main Functions
When energy balance is 0, the meter can send out power off signal to control load for
auto switching off, and it shall auto restore the power supply after the new purchased energy
is loaded.
Record events of open terminal cover trip, open face cover trip, overload trip, power off,
reverse tampering, phase off, relay off, time synchronization, power purchase, meter
reset, demand reset, event reset and data alteration tampering, etc. (see 4.14 Event
Recording Function)

1.1.4 Additional Functions
Active energy multi-tariff metering.
Demand calculating.
Auto detection.
Realize users’ load detecting and controlling.
Detect grid parameters including real-time power, voltage, current and power factor.
Enable to display by pressing buttons after power outage.
1.1.5 Major Features
Prepaid mode- it is a power consumption mode by paying first and using electricity later.
APL SEM 3P V2 Three-phase Keypad Prepayment Energy Meter takes amount as its
electricity billing. In conditions of prepaid mode, electricity consumer purchases amount
at first and the meter subtracts the remaining credit amount equivalent to the
consumption. When remaining amount is 0 or the overdraft energy allowed by both
parties, it will send out power off signal to control load switch automatically cut off.
APL SEM 3P V2 Three-phase Keypad Prepayment Energy Meter adopts CTS algorithm,
which has a set of security management system with a high-level security and is
completely compatible with the CTS management system deployed in Bangladesh.

2. Technical Parameters
2.1. Operating Voltage

Rated voltage Un
3×230/400 V

Operating voltage range
60% Un ~ 130% Un
The meter can work normally within the operating voltage range.
Limited range of operating voltage 0 Un ~ 190% Un
Within this limited operating voltage range, the meter will show no damage. It can
guarantee metering during normal display, but cannot ensure the metering accuracy
class.
Meanwhile, the load control equipment cannot operate. After the operating voltage returns
to normal, the meter can work normally and the accuracy class will remain unchanged.
2.2. Current Parameters
Imax 100 A
Starting current (0.4%Ib) 40 mA
Metering current range 40 mA ~ 100 A
Common current specification 10(100) A
2.3. Frequency Parameters
Rated frequency fn 50 Hz
Frequency application range 47.5 Hz ~ 52.5 Hz
2.4. Self- power Consumption of Meter
Power consumption of voltage circuit ≤2 W 6 VA
Power consumption of current circuit ≤2.5 VA
2.5. Active Metering Accuracy
The accuracy of active energy measurement of APL SEM 3P V2 conforms to
IEC62053-21 Class 1.0.

2.8. Active Check Output
The meter is equipped with special pulse indicator for testing active energy (LED is on the
nameplate of meter). In order to ensure the accuracy of active measuring test, according to
different current test points, pulse quantity collected from test should be incremented with the
increase of current, and reasonably select pulses between the numbers 1~8.
