Energy meter with wireless CIU/UIU
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 energy is equal to credit warning threshold, the meter will start the audio & video warning function in a way of warning light flashing
