Cashpower 3 Phase
A three phase split prepayment meter
The Cashpower Three Phase meter is a four-wire 100 Amp per phase, keypad-based prepayment meter in a compact BS housing. The meter is suitable for residential, commercial and light industrial environments. An optional local keypad and display can be fitted to the meter at the time of manufacture. The meter also features a dedicated diagnostic indicator which shows the status of communication to the remote customer interface unit. The meter boasts a large custom display and also features a host of standard Cashpower software features including the ability to operate as a prepayment meter or in credit metering mode.
As a standard feature, the Three Phase meter offers an IEC 62056-21 compliant optical communications port. This allows the utility to access a variety of information stored inside the meter and to upload it to a hand-held unit.
The Cashpower Three Phase meter is mechanically sealed against tampering through the use of factory sealed plugs and optional sealing wires for the electronic enclosure. In addition the terminal cover can be sealed by standard utility seals.
The Cashpower Three Phase meter is equipped with a tamper sensor that will automatically disconnect the power to the load in the event of tampering.
The meter has been designed to have a surge voltage withstand that significantly exceeds the requirements of both SABS 1524 and IEC 62052-11.
Remote Customer Interface Unit
The meter has two parts, the prepayment meter and the customer interface unit. The meter is connected to the customer interface unit by a two-core communications wire up to a distance of 130 metres. It operates independently of the customer interface unit and is usually installed in a secure, locked enclosure outside the consumer’s home. The customer interface unit is compact with a user-friendly keypad and display. An optional local keypad and display can be fitted to the meter at the time of manufacture. The meter also features a dedicated diagnostic indicator which shows the status of communication to the customer interface unit.
The meter contains all critical metering, token decryption and load control functionality. It operates independently and is immune to any form of tampering on the Customer Interface Unit.
The meter is usually installed outside the home in a secure, locked enclosure which should not be accessible to the consumer. This facilitates easy inspection by the utility at any time and reduces the opportunity of fraud by tampering.
The customer interface unit is installed inside the consumer’s house in a convenient location. The communications interface can withstand voltage surges of 6kV, however it is recommended that one of the communication lines be earthed at the meter for additional protection.
