Functions

• Tamper and fraud prevention function

Meter is divided into two parts
12
Function

• CPU card is adopted

CPU card is adopted as customer card And ESAM
security module in meter is Provided to carry
out 3DES encryption Authorization. One meter
corresponds to One card to achieve perfect
security.
13
Function

• CPU card has function of data readback

14
FUNCTION

• The meter has a tri-color LED to indicate the
  available credit levels clearly and directly.

15
FUNCTION

• Three levels alarm threshold

Three levels alarm threshold can be set
Available credit is enough
Available credit 30, not enough
Available credit 20
Available credit 10, meter maybe cut off soon
16
FUNCTION

• Communication function

• The meter is equipped with an infrared interface,
  via the port, can perform following operations
  credit loading, relay controlling, load threshold
  programming etc.

19
QUALITIES

• We took the best raw materials for example the
  PCB shell used for the meter are very strong, it
  is very difficult to damage if it falls down or
  is hit by a very hard object.
• The LCD materials are all imported from Germany
  which can be used for more than 20yrs and it can
  withstand a very high temperature of 70?

20
PRODUCTION TECHNIQUES

• We adopted advanced production technique jointly
  from the best product in the world with zero
  pollution. Our factory has passed the ISO14000
  certification.
• We are using advanced production equipment and
  put together by high precision computers
  automatically without interruption of any kind.
  This is the first modern special production line
  of China for meter production.
• We have a strict management of meter production
  according to advance quality management system.
  HENAN STAR is the first meter factory to get the
  ISO9001 in China. We have continue our meter
  production according to this quality standard for
  more than 10yrs

21
PRODUCTION TECHNIQUES

• We re-evaluate all the quality of Nigeria meter
  to meet the climatic condition, all meters
  delivered here are of the highest grade and we
  can confirm that no other PPM can be compared to
  our meters.
• Unistar is the first company in Nigeria to teach
  Nigerians how to produce and install the
  prepayment. These expose us (HENAN STAR) to have
  experience. We believe that we can offer all best
  all round technical and support service with the
  assistance of our Nigerian engineers.

22
FEATURES OF PRODUCT

• We have all types of prepayment, we have single
  phase compact and split meter, three phase
  compact and split meters. We also have prepayment
  without wire i.e. remote control to control it we
  also have prepayment meter without wire
  controlling it (remote control) and also
  prepayment meters that uses key pads. Our meter
  also have the current rating of 100A and of
  course other smaller current rating like 40A, 60A
  etc
• We also adopted CPU card technique which nobody
  can open i.e. the data are highly secured.
• This technique can be compared to the advance
  bank secret system. We also adopt the split
  technology to check tampering or by passing. We
  also incorporate the advance vending software
  system to be controlled on the meter and billing
  or vending on-line.

23

• FEATURES OF PRODUCT

• We have made use of the best software together
  with advance technique so as to ensure serious
  monitoring of the meter i.e. we can analyze the
  billing data and print the report to detect the
  customers that did not vend according to required
  amount.
• We also have a protection device in the meter in
  case the customer overloads his or her supply,
  instead of fire the meter will trip off, the
  meter can be revived with the customer card after
  necessary correction on the load. However, we can
  design other electric meters according to
  Nigerian request

24
PRICE

• The price of our meters are very competitive
  considering their robust configuration, quality
  and efficiency. If we pay peanut, we get
  monkeys. Quality of PPM in an environment of
  likely power outage cannot be over-emphasized.
• Compact PPM already in use are obviously cheaper
  all over the world but prone to tampering.
• Our Split PMM come with the following value added
  functions
• It has high accuracy, stability and long life
  span.

25

• The CPU card has data read back function
• International warranty against manufacturing
  defect
• After sales service in our local factory
• On-line vending facility
• Monitoring of each meter against tampering
• Difficult to by-pass
• Assurance of high recovery and higher revenue
  collection
• It has a high capacity for surge resistance
• It has protection against over load and theft.

26

• It has a tri-colour LED to indicate the available
  credit level on the meter
• It can display cumulative energy consumption and
  operation recorded in turn
• It can identify on the LCD automatically the
  nature of fault on the meter, if at all it has a
  fault
• The meter case material is flame resistant,
  rainproof and is protected from dust and solar
  radiation
• It has cooling mechanism for solving internal
  heat
• The insulation test is 2Kv AC/min

27
SECURITY

• One card, for one meter, and vice versa
• ESAM Module
• IC card with CPU
• 3DES encryption arithmetic
• 7 kinds of cryptographic key

28
Summary

• Digital design
• Metering, Data transmission, Display
• Comply with international Standards
• ISO14000,ISO9001
• Prepayment function
• Anti-tamper
• The meter has perfect anti-tamper functions
  because customers cannot access to the metering
  unit.
• Short-circuit, phase and neutral interchanged
• High security
• Smart Card, 3 DES, Seven Keys, ESAM Module
• Personalized design
• Installation, convenience, maintainability
• High rate of performance/cost
