![]() ![]() ![]() ![]() Secure data transfer takes place via an encryption algorithm included within the Standard Transfer Specification (STS) and all correctly entered meter specific tokens are registered, eliminating token fraud. A user- friendly interface is ensured through the large format custom designed LCD display, a visual consumption rate LED and the numeric keypad data entry terminal.Įach meter has a unique security key and credit is entered into the meter in the form of a secure 20 digit token, through the numeric keypad. The UIU provides the user with a convenient interface to the remote MCU. This includes the power supply, reset circuit, disconnection circuitry, power measurement, nonvolatile memory, three disconnect contactors rated at 250 Amps per phase, over temperature sensing and tamper detection. The MCU contains the measurement and control circuits. The UIU draws its power from the MCU via the current loop communication wires. ![]() This allows utilities to mount the MCU in a location where it is readily accessible, while the UIU is installed at a point of convenience within the customer’s premises. The split meter is unique in that it separates the user interface unit (UIU) from the Measurement and Control Unit (MCU). The meter provides a cost effective control of loads of up to 250 Amps per phase, and is an ideal unit for industrial and commercial applications requiring enhanced security and convenience. The BEC33HC is a three phase four wire, Class 2, split configured prepayment electricity meter.
