Three Phase STS Keypad Prepaid Electricity Meter


The DTSY150-K is a four-wire, 100 Amp per phase, keypad based prepayment meter in a compact BS housing. It is ideal for large residential homes, small commerical and industrial applications. The meter is manufactured to ISO9001 standards. It has an IP54 protection rating, wide range of power supply(Un-40%+20%) and improved RF immunity withstand of 30V/m, allowing it to be installed in harsh environments. It provides measurement of both active and reactive energy. 

Functions and Features: 

1. Maximum demand measurement
2. Adopt 20-digit token as data transmission media, you can purchase energy before consumption;
3. Detection of significant reverse energy(SRE)
4. IEC62056-21 compliant optical&RS485 port allowing data transmission.
5. disconnect on overload and no credit
6. prepayment and credit mode hot swap
7. programmable load limit and low credit warning
8. detection and record tamper event such as opening cover, reverse connection, black-out. 
9. Easy access to 12 months historical consumption data and last 5 token enter. 

10. Meter provides detailed power information such as phase voltage, current, total active power, reactive power, apparent power, total power factor, power grid frequency.

AMI&AMR Smart Metering Function(On Request):

1. Easy connection to User Interface Unit( UIU) for split type connection.

2. PLC/RF/GPRS/GSM communication with head-end AMR/AMI server.
