Split Keypad Prepaid Single Phase Electricity Meter with CIU
A split keyboard means that the electricity meter is equipped with
a separate user interface unit (CIU).
So what is CIU? Customer Interface Unit (CIU), is offered to enter
recharge tokens and information by short codes. A communication
module will be installed in CIU to facilitate users to check the
use status, recharge or query the information they want to know at
any time when the electricity meter is elsewhere and users cannot
reach or touch inconvenient places.To do this, you just need to
enter the corresponding broken code on the CIU keyboard.However,
there is only one corresponding CIU for each user's electricity
meter, and their table number is corresponding to facilitate the
information exchange between each other.Avoid interference between
two users who are close to each other and have the same CIU number
when sending messages.Therefore, if the User's CIU is lost or
damaged, it will be a trouble to replace it with a new CIU. The
manufacturer needs to re-install the CIU with the corresponding
table number and reset it.These operations down, will take a lot of
time, and will incur some costs.Therefore, attention should be paid
to the use of CIU to avoid damage and loss.
Main characteristics
● Meter Recharge By Inputting TOKEN
● Active energy measurement
● MD(maximum demand measurement)
● Auto scroll mode display
● Build-in relay control

Main Functions:
●Prepaid function: can only use water after paying, close water
valves after running out of water.
●Low credit alarm:when the remaining electric quantity is less than
the alarm quantity, the electricity meter often shows the remaining
electric quantity to remind the user to buy electricity.

or post-paid mode.
●Measurement function:user can measure the electricity
consumption,the credits,etc.
●TOU Tariff:utilities can set step price on request.
●Event recording:meter can record the tamper event, open cover
event, purchase event and TOKENS.
●Self-testing:meter has a self-test function, it can test LCD and
relay etc. and report the results directly.
●Anti-tamper:meter will automatically close the valve after
detection of magnetic field and cover-opening event.

day or month by month.
●Communication:the meter is available with AMI system through LORA
RF or Bluetooth 4.0 on request.
●Load control function:meter can be programmed for load control
threshold, If the current power is more than threshold. The meter
will cut off user load.
●Information Inquiry:consumer could check the data like credit
remain, total purchased and total credit by inputting the short
code.
