Automatic power supply detection

Power supply requirements

The meter can be supplied with power via a battery or via power supply mod-
ules as preferred. Battery and power supply are replaceable at any time.
Options:

6 years battery

11 years battery

16 years battery

Power supply 230 V AC

Power supply 110 V AC

Power supply 24 V ACDC
*) From 2018 replaced by a wide-range power supply 100 - 240V
The power supply detects whether a line voltage is applied. This signal is
routed to the meter. That enables the device to detect automatically whether it
is being powered from a battery or power supply.
Requirements
(for measuring timebase Q = 4
s and time base T = 30 s)
Standard pulses,
M-Bus read out (max. each
15 min.), CL-Module
Radio module 868 MHz (mo-
bile radio; 16 sec. transmis-
sion interval)
Radio module 868 MHz (sta-
tionary radio; 15 min. trans-
mission interval)
M-Bus fast read out (max.
each 4 sec.), fast pulses,
analog module
Fast measurement raster
(for measuring timebase Q =4
s and time base T = 4 s)
Note: The lifetime of battery depends on the type of battery and on
the requirements.
Note: Only batteries approved by the manufacturer may be in-
stalled.
