C11 - Easy and compact
EQ meters
The EQ meters C11 is a truly compact meter for single
phase metering. The C11 is mounted on a DIN rail and is
suitable for installation in distribution boards and small
consumer units.
The C11 is suitable for many applications.
General features
The C11 is a very compact meter for single phase applica-
tions. The meter has an LCD with large digits on a vertical line
and small digits on a horizontal line below. The meter has a
wide temperature range which makes it possible to install the
meter in many locations. Navigating the meter is easily done
via the push-button below the display. The power consump-
tion of the meter is very low, less than 0.8 VA (0.2 W).
Communication
Data from the C11 meters can be collected via pulse output.
The pulse output is a solid state relay that generates pulses
proportionally to the measured energy.
Instrumentation
The C11 meters support reading of instrument values.
A number of electrical properties can be read:
• Power factor • Active power
• Current • Voltage
Outputs
The C11 meter has an output that can be used as pulse
output or alarm output. The alarm quantity and levels is easily
configured on the meter with the push button. The output can
be used for controlling external apparatus like a contactor or
an alarm indicator (connected via an external relay).
Approvals
The C11 meters are type approved according to IEC as well
as type approved and optionally verified according to MID.
MID is the Measure Instruments Directive 2004/22/EC from
European Commission. The type approval is according to
standards that covers all relevant technical aspects of the
meter.These include climate conditions, electromagnetic
compatibility (EMC), electrical requirements, mechanical
requirements and accuracy.
