Product Description

DTSY150   Three Phase Keypad Prepayment Electric Meter
The DTSY150 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 commercial 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.

 20 digit (Standard Transfer Specification) STS encryption
 Detection of significant reverse energy (SRE) 
 IEC62056-21 compliant optical & RS485 port allowing for easy data interrogation

 Main Features
  • Energy Measurement
Total and time-sharing forward active & reactive energy measurement
Total and time-sharing reverse active & reactive energy measurement
Save last one to sixteen months energy data
  • 20 digit Standard Transfer Specification(STS)
Credit data transfered from a point of sale (POS) or vending system is made into a numeric token  in a 20 digit number using the Standard Transfer Specification (STS) encryption techniques, which comply with IEC62055 protocol
  • Load control function
When the residual energy is 0 or the allowable overdraft that both sides agreed, this meter will send out power-off signal to have load switch cut off power. The power will be recovered automatically after inputting new purchased energy amount.
  • Programmable low credit warning
The meter can be programmed for setting user credit warning threshold, When the meter's residual energyis equal to credit warning threshold, the meter will start the audio & video warning function in a way of warning light flashing.
  • Tamper detection
With event recording function (including cover-opening event, tamper event and power failure event)
  • Max. Demand Measurement
Measure total and time-sharing forward active & reactive maximum demand and time of occurred
Measure total and time-sharing reverse active & reactive maximum demand and time of occurred
Measure total forward & reverse apparent maximum demand and time of occurred
  • Real Time Measurement
Real-time measurement of the phase voltage, current, total active power, reactive power, apparent power, total power factor, power grid frequency
  • TOU
4tariffs, 100holidays, 14seasontables, 8time zonetables, each table on maximum 14 time zones
  • Event Log
