Energy Harvesting Pulse Counter

Energy Harvesting
Pulse Counter

An energy harvesting, pulse counter designed to count pulses from an installed electricity meter and output a KWh reading via the EnOcean® Wireless protocol.

Designed to be installed onto an existing electricity meter, the Pressac energy harvesting pulse counter takes it’s energy from the power cable supplying the meter via a CT clamp. A very small amount of energy (<30W) needs to be flowing through the meter at the time of pulse measurement and telegram output.

Connection to the electricity meter itself for pulse counting is via a standard ‘dry contact’ relay output or an open collector output from the meter.

Depending on meter type, the number of pulses to be counted for a KWh measurement can be configured between 0.1 pulses per KWh and 1000 pulses per KWh via DIP switches.
