Cashpower ECU
Common base meter with built-in earth leakage and circuit breaker
The new generation Cashpower ECU is a compact, single-phase, two-wire, keypad-based prepayment electricity meter in a housing compatible with the ESKOM standard common base electricity dispenser socket.
The ECU which has built-in earth leakage and over current protection, is most suited to new reticulation and is directly and easily interchangeable with common base prepayment meters from other approved manufacturers using the common base configuration.
User interaction with the meter and access to meter information (such as a low credit warning, energy consumption and load contactor status) are available using the keypad and LCD display.

Principle of Operation
The ECU meter is based on the ESKOM specification which calls for a prepayment meter that can be fitted into a standard plug-in base. This concept ensures simple installation and replacement procedures.
The meter is keypad-based and supports the industry-standard STS encryption algorithm.
Access to meter information is available using the keypad and LCD. More detailed information and programming is achieved via the standard interrogation port at the rear of the meter, according to the defined ESKOM specification.??Integration of a supply isolator, earth leakage protection and over current and short-circuit protection into the prepayment meter eliminates the need for a distribution board in the house, thereby reducing overall installation costs.
