DESCRIPTION

The SAMES SA2007H is a single phase bidirectional dual element energy metering integrated circuit. It provides a simple analog interface to a micro-controller and is specifically designed for meter manufacturers to have full control over the meter functionality.

The SA2007H has two current sensor inputs. The power consumption on both inputs are continuously measured. A typical application would be to monitor Live and Neutral lines for tamper detection.

For each current sensor input the SA2007H integrated circuit has a corresponding pulse output, each generating a pulse rate with a frequency proportional to the power consumption measured on the specific channel.

The SA2007H performs active power measurement and takes the power factor into account. Energy consumption can be determined by the power measurement being integrated over time. The energy flow direction information is also available for each channel.
