Introduction
Product Description
The MD-P1 and MD-P1D Power Meters monitor the voltage, current, power, energy
and many other electrical parameters on single and three-phase electrical systems.
The meters use direct connections to each phase of the voltage, and use current
transformers to monitor each phase of the current. Information on energy use,
demand, power factor, line frequency and more are derived from the voltage and
current inputs.
The communications interface to the meters is an RS-485 serial connection that uses
the Siemens P1 FLN protocol for sending commands and retrieving data. An APOGEE
Building Management and Control System is usually connected to the MD-P1 or MD-
P1D Power Meter. This APOGEE system unit provides data recording and trend
logging plus a human interface or display.
Up to 20 MD-P1 or MD-P1D Power Meters may be connected to a single P1 network
for monitoring and recording power usage at multiple locations within a single site.
The MD-P1D Meter, with an integral 2-line × 16 LCD display provides visual feedback
of volts, amps, and Kw, (see Appendix C).
