Power Probe
The PSP Power Probe is a three
phase data logger, quality of
supply monitor, and remote
terminal unit for demand-sidemanagement.
Historical information of two months
is kept in non volatile memory for
later analysis.
Communication options to the unit
include direct connection to a
computer or PDA serial port, dialup modem, or real-time
communication via the internet.

Functions
The Analog Devices ADE7758 poly
phase multifunction energy
metering chip is the core of all
measurement in the Power probe.
It is presently the most advanced
metering chip in the world. The full
functionality of this chip is exposed
via a powerful main processor and
communication protocol.
Independent per-phase information is
kept in non-volatile memory for
active energy, reactive energy,
voltage peaks, voltage dips and
power-downs.
