*12*****
Industrial Power Supplies 90-250 V AC, 24 V
DC or 12 V DC Distributed Power Systems.
This module is necessary for the complete
flowmeter.
Electrical Specifications
Input Voltages ±5% /
possible current
consumption
AC 90 - 250V / max. 15 VA
DC 24 V / max. 600mA
DC 12 V / max. 1050mA
R = 50mm
H(230V) = 58mm
H(12,24V) = 58mm
The device does not have a network power switch. For any electrical work or housing open it is
necessary to disconnect the device from the network power, and this has to be done via a switch.
The mains protective earth wire has to be connected to the PE terminal (power supply class 1). A
switch or circuit breaker (B6) has to be in the building installation if mains supply 90 – 250 V AC
from building installation is connected to the power supply module. It must be in close proximity
to the equipment and within easy reach of the operator, and it shall be marked as the
disconnecting device for the flowmeter.
