VPInstruments - 3 Phase Power Meter - User Manual

Congratulations on your purchase of the 3-Phase Power Meter - Wide-Range Modbus. This meter offers precision energy and power measurements in a compact package. It enables you to
make power and energy measurements within existing electric service panels avoiding the costly
installation of subpanels and associated wiring. It is designed for use in demand side management, submetering, and energy monitoring applications. The meter communicates on an RS485 two-wire bus using
the Modbus protocol. The one model covers all applications including single-phase, three-phase wye, and
three-phase delta configurations for nominal voltages from 100 VAC to 600 VAC at 50 and 60 Hz.
The meter is self-powered from the mains connection. In addition to low voltage applications, the meter
can be used in medium voltage applications (normally 2300 Vac and 4160 Vac) because potential
transformer (PT) ratio scaling is available.
