The AEMC PEL 102 is a low cost, simple to use, one, two (split-phase) and three phase (Y, Δ) power/energy data logger. The PEL 102 (2137.61) has no display or sensors. The PEL 102 is ideal for electricians, engineers and contractors doing work in the area of building and system monitoring and upgrades, as well as residential energy audits. All vital energy data is easily measured, recorded, analyzed and reports are generated with confidence and minimal configuration time and effort. This logger has many up-to-date features demanded by the present market conditions.
The PEL 102 offer all the essential functions for data logging Power/Energy from most of the electrical power networks in use today. The PEL 102 energy loggers can measure three voltage and three current inputs and records these inputs, as well as Watts, VARS, VA and energy (kWh, kvarh and kVA). Power factor, displacement power factor, crest factor, frequency, neutral current and THD are calculated and recorded as well. Individual harmonic information as a % of fundamental out to the 50th harmonic is also recorded at the operator’s choice. All variables are recorded and stored on a one second basis and on user selectable demand intervals from one to sixty minutes. Energy costs can be calculated and displayed quickly and easily by simply programming in the unit cost for a kilowatt hour. Data is stored on a removable SD card. Data can be retrieved by USB, Bluetooth and/or Ethernet (local or internet) connection, as well as transporting the SD card back to the download site.
