ACTIVE ENERGY MEASUREMENT – DIRECTIVE 2004/22/EC (MID)
Energy meters are mainly intended to measure energy for billing purposes
In European Union, every measuring instrument for billing must comply with and be certified according to MID (Measuring Instruments Directive)
The energy meter is designed to be safe and accurate (Type tests).
MID warrants
The energy meter is produced to be safe and accurate (Production conformity ).
All DMED energy meters are available in a version with MID approval.
“MID” suffix at the end of order codes.

ACTIVE ENERGY MEASUREMENT – ACCURACY
MID and non-MID active energy meters comply with different standards:
Non-MID: IEC/EN
MID: EN
A complete correspondence between the two standards does not exist.

STATIC OUTPUT
The static outputs can be:
Pulses for active energy counting (kWh)
User programmable in order to get:
Automatic reset.
Overtaking of a limit threshold on a controlled measurement
Pulses for active energy (kWh) or reactive energy (kvarh) counting.
After K pulses, 1 kWh is counted (accumulated).
M40 GB

11. ENERGY METERS DME SERIES
STATIC OUTPUT PROGRAMMED AS LIMIT THRESHOLD
50mA at 24VDC
The overtaking of the limit threshold enables a buzzer to advise the user about a power shutdown.
8LP 2T ZGB
Adding a timer, the static output can enable the buzzer and a timer that, after the programmed delay, opens a non-priority load.
TM M2
The information is transmitted to a programmable relay to:
Display a message.
Enable a buzzer.
Enable timers to open non-priority loads.
Let the user choose which load should be disconnected using the front panel keys.
