ABSTRACT:
An electronic meter that is capable of handling an analog cellular phone or radio modem under the meter cover provides significant improvements in the thermal management and power handling that is associated with a circuit switched wireless device. The electronic meter comprises a power supply capable of delivering the transmitter power plus the associated losses due to transmitter efficiency. It is desirable to deliver the high power over a wide range of AC input voltages (typically from about 90 to 530 VAC). The meter packaging allows the power supply and the analog cellular modem to operate in an enclosed metering package without exceeding the operating temperatures of the electronic components. The packaging adapts to increased steady state (idle) conditions as well as increased transmit conditions.
