Cognitive advantages of STS meters through comparison

Prepaid meters are widely used in Africa, Southeast Asia and other countries, and they are also respected in the rental housing market. Prepaid meters and postpaid meters have major differences in the management mode of electricity sales.

1, prepaid meters "pay first and then use electricity" to effectively solve the problem of hard to get charges

2, no manual meter reading, electricity collection, the user independent door-to-door purchase of electricity, saving a lot of manpower and material resources

3, prepaid implementation of the management of pre-charge, can solve the problem of shortage of funds

4Built-in magnetic holding relay can be used for power limitation to protect cables and power equipment; over the set power automatic power off protection

 

There are various types of prepaid meters in the market: STS code type prepaid meters, card meters, numerical prepaid meters; today I would like to list the differences between different types of prepaid meters

Compatibility

STS standard transmission specification is currently the only globally recognized open standard for prepaid systems; high compatibility

Different IC cards use different encryption methods, and different manufacturers' meters use different protocols, resulting in low compatibility

Different manufacturers use different encryption methods and protocols; low compatibility

Cost of electricity purchase

Power can be purchased online by recharging via remote communication. Low cost of electricity purchase

bringing your card to designated sales points

High cost of electricity purchase

Power can be purchased online by recharging via remote communication.

Low cost of electricity purchase

Security

20-bit code, can only be cracked for a single table, high security

AES encryption, not high security

AES encryption, not high security

Fault Tolerance

Communication failure can be recharged by entering the code through the keyboard

IC card damage can only be replaced

Communication failure can not be recharged

 

According to the comparison of index contents in the above table, we can obviously see that STS meters have greater advantages in compatibility and expandability, convenience of purchasing electricity, transmission security, and fault tolerance in use. The STS meters and STS electricity sales system developed by Yongtailong have been certified by STS Association; in STS prepaid meters there are even more series of products to meet the needs of different customers, single-phase STS meters, three-phase STS meters, STS anti-tamper meters, smart prepaid electricity meter, STS split energy meters, wall mounted STS meters, Din rail mounted STS meters, etc.
