SPEED™ LD-1200 Recorder    Data Bulletin

The LD-1200 Field Recorder collects data at the breaker panel location and is designed to be used in situations where installation at the meter base is either not possible or not permitted. Periodically this data is uploaded for processing using Enetics' SPEED™ algorithm, which produces energy consumption interval data for each major appliance in the residence.

Installation typically involves connection to the phone line (if present) at the site. Typically, the unit shares the premises phone line for periodic uploading of data and recorder management ("walk-up" data collection methods are also available). The LD-1200 is configured for single and 2-phase residential services.

The recorder samples the power line and computes watt and VAR values. It senses transitions in these parameters and uses this information to determine exactly when a particular appliance turns on or off. It then records, calculates and stores the date and time of each on/off event along with the voltage, real and reactive power (watt, VAR). The recorder also computes and stores the whole-building watt-hour and VAR-hours for each recording interval. The recorder can also log internal temperature if the Plug-in Temperature Sensor is in use at the premises.  The LD-1200 is functionally the same as the LD-1100 model, but includes two external CTs as well as increased memory.

Key Features

  • Rated for 200A direct metered service
  • Includes two(2) external CTs.
  • Records whole house energy consumption by interval
  • Records edge data for appliance consumption analysis.
  • Built-in phone modem (optional); external cellular modem (optional)
  • Data transfer to Master Station via phone (with optional modem) or walk-up

For applications where a separate channel is required to monitor an alternate energy source such as a fuel cell or photo-voltaic array, Enetics has created the LD-1203 AES recorder.  Click here for more information.
