MULTICAL® 603
10 Power supply
MULTICAL® 603 is powered via the two‐pole connector in the calculator base. The internal power supply is 3.6 VDC
and can be carried out as battery or mains supply via a number of different supply modules from Kamstrup A/S, see
the below extract from the type number overview in paragraph 3.1.
Supply modules
Battery, 1 x D‐cell
230 VAC high‐power SMPS
24 VAC/VDC high‐power SMPS
230 VAC supply module
24 VAC supply module
Battery, 2 x A‐cells
All supply modules have been evaluated in connection with the extensive type tests, to which MULTICAL® 603 has
been subjected, and it is not permissible to use other supply modules than the ones mentioned above. The supply
modules are covered by the CE‐marking and the factory guarantee of the meter.
Note: The modules for mains connection must not be connected to direct current (DC), however except for module
no. 4 "24 VAC/VDC High power SMPS".
10.1
Lithium battery, 2 x A‐cells
Battery supply for MULTICAL® 603 can consist of a supply module which uses 2 x A‐cell lithium batteries (Kamstrup
type HC‐993‐09). No tools are required in order to mount or replace the battery module. Each battery cell has a
lithium content of approx. 0.9 g, which excepts the module from being subject to regulations for transportation of
dangerous goods.
The battery lifetime depends on factors like ambient temperature and meter configuration, an indication of battery
lifetime is thus a realistic estimate.
