STS SABS Approved Digital Prepaid Electric Meter Prepayment Electricity

General description

The meter is with advanced measuring chip with high reliable CPU, and manufactured with advanced SMT Process. The main features are:

l Bidirectional active energy measurement, reverse energy accumulated to positive energy.

l Measuring the total accumulative and remaining energy.

l The meter will automatically switch off when the remaining power was used out.

l Using the STS encryption techniques and protocol to generate 20 digits cryptograph which can be used to charge energy, set key, clear tampering sign and so on.

l Multi-level remaining power, the meter will alarm when the remaining power is low.

l Credit overflow limit: If the credit amount transferred plus remaining credit more than credit stock limit, then the credit amount transferred will be refused, but the Credit amount transfer token is still valid.

l Alarm: When remaining credit crosses the minimum credit (5.00kWh,2.0kWh, 0.5kWh), the warning LED glitter,LCD also indicates the warning symbol to remind user to purchase credit. Buzzer buzzes should customize.

l Open upper cover and terminal cover detection whether the meter is power on or off.

l Switch off when the power is over the set value.

l LED pulse light output.

l Pulse output energy

l Design the meter according to IEC 62055-41, IEC62055-31, and IEC 62055-51.

l Charge the meter through SMS, internet and so on.

l High reliability and accuracy, easy to use.

Meter data check

We can use two ways to check.

1. Through STS test command to check the data.

l Switch on/off

TOKEN: 0000_0000_0001_5099_7584 is used to test the relay. The relay operate two times (switch on and switch off) and back to the original status when the meter received the command. (If the meter with zero energy, the meter will show that the relay has on operation)

l Full screen

TOKEN: 0000_0000_0001_6777_4880 is used to display the full screen one time and then back to the original status.

l Display the total active energy

TOKEN: 0000_0000_0002_0132_8896 is used to display the total consuming energy and back to the original status.

l KRN

TOKEN: 1844_6744_0738_4377_2416 is used to display the KRN value and back to the original status.

l TI

TOKEN: 3689_3488_1475_5332_2496 will display the TI value.

l Test all above function.

TOKEN: 5649_3153_7254_5031_3471 will test the whole above test one time and back to the original status.

2. Through input the command refer to 2.2.


Over power alarm

The meter will come into over-power status when the power is larger than the value that we set. The meter will show “OU_LOAD”. The over power symbol will lose only when the power less than the set value. Using keypad input 09+enter key to show the present power, input 07+enter key to show the over power value.

The meter also has the following function.

l When the meter is over power for 3 seconds, the meter will show over power status.

l The over power status is last more than 45 seconds; the meter will switch off and switch on 150 seconds later.

l If the total over power time is more than 45 seconds in half an hour, the meter will switch off and switch on 150 seconds later.

l If the meter switches off more than 5 times in 30 minutes because of over power, the meter will switch off for 45 minutes before switch on again.


Low energy alarm

When the remaining energy is lower than the set value, the Led will change from yellow to red flash and the buzzer will ring. We can put any key to close the buzzer, but the buzzer will ring again after some time. With the energy reducing, the led will flash more quicker and buzzer will ring louder. When the energy is 0, the meter will switch off.

Set parameters that related to the lower energy value:

l 123xxx: Set time to make the buzzer ring again. After setting, put any key to close the buzzer, then the buzzer will ring again automatically after xxx minutes.

l 456xx: Set the lower energy value. After setting, the meter will alarm when the remaining energy is lower than xx.

l 567xx: Set how long the buzzer will ring. After the meter ringing xx minutes, the buzzer will ring XX minutes. (the same as we set)

4.7 Clear the energy

The operator can use STS command to clear the remaining energy. The meter will display “BENAR” when the meter accepts the command. Then the energy will be 0 and the relay will be switch off.

4.8 Change the Key

The customer can change the key through the STS command which complies with IEC 62055-41.

Refer to the following column to check whether the different level key can change each other.
