Energy Measurement and Management
ME341
Residential electronic single-phase meter
ME341 is a residential singlephase
meter designed for direct
connection and metering of
active energy. It is based on
electronic principle and destined
for the Blue Tariff (Tarif Bleu)
customers of the Electricité de
France for contracted power not
exceeding 18 kVA.

TECHNICAL CHARACTERISTICS
Measuring principle
Electric current is measured by shunt resistance. Signals proportional to the
current and voltage are fed to a microcontroller A/D converter. Active electric
energy consumption is determined by digital multiplication and subsequent
time integration.
User interface
– Liquid Crystal Display (LCD) controlled by two push buttons DEFILEMENT
and SELECTION
– Light Emitting Diode (LED) indicating the energy flow
– PROGRAMMATION push button for local programming of the meter
Communication interfaces
– Bi-directional Telereport interface with data exchange in compliance with
IEC 62056-31
– Unidirectional Teleinformation output for the customer’s use
Bistable relay output for local control of load
– Hot water preparation and heating (typically 2 A, 250 V)
– Customer circuit protection: 4 A fuse
Ripple-control receiver
– Integrated ripple-control receiver for 175 Hz according to
EDF HN 96-S-65, section 7
– Ripple-control receiver available in the 175 Hz half-rate version for the
Overseas French Departments and Territories (DOM-TOM)
Meter housing
– Made of self-extinguishing polycarbonate, assuring IP51 protection level
against dust and water penetration
– Designed to be vertically surface-mounted on a metering panel, attached
to a DIN rail of 35 x 7.5 mm according to DIN 50-022
Anti-fraud and security functions
– Sealed power terminals cover and customer terminals cover
– Integrated device for detection and registration of the power terminals
cover removal
– LCD segment test activated by a push button
