The OPP-1 from Solid State Instruments is a convenient and low-cost way to monitor energy consumption information from compatible utility meters with no physical electrical connection. Using the meter’s infrared calibration pulse on the Optocom port, the OPP-1 picks up the infrared light flash (pulse) each time a pre-determined number of watt-hours (usually 1 Kwh) is consumed by the customer’s premises. In this way, the utility, their customer or their energy management contractor can read power from their meter temporarily for doing load survey, demand response or energy management activities quicker and at much lower cost.
Solid State Instruments’ unique pulse isolation and conditioning technology allows the calibration pulse to be picked up and converted into standard Form C metering KYZ pulses to interface with power monitoring equipment that uses a pulse input.
The electric meter must have the calibration pulse as the default mode on the Optocom port when the port is not being used for data uploading, downloading or other programming activities. The OPP-1 is a one directional device with read-only capability. It provides a truly secure method of acquiring power monitoring information with no hassle.
Known meters which are compatible with the OPP-1 are:
Landis + Gyr Model S4e
Landis + Gyr Model MAXsys Elite
GE Model KV2e
Elster Alpha 3
