3. Power supply
3.1 IMB power supply modules
The power supply of an IMBus can be carried out by the USB port of the PC on using an IMB-usb con-
nection cable. If the power consumption does not exceeds the specified value of the particular USB-port,
then there is no extra IMB power supply module necessary. On all other IMB-Connection cables / mod-
ules an extra IMB power supply module is necessary.
Approximate power supply by USB ports :
-
Standard USB ports
:
Iout = 500 mA ( max. )
-
USB ports of devices supplied by batteries
:
Iout = 100 mA ( max. )
-
USB ports of USB-hubs without external power supply
:
Iout = 100 mA ( max. )
!!! Please mind the technical specification of the USB port of your device
IMB power supply modules :
IMB-ps2 (
Switching power supply with wide voltage input 85 – 260 V AC
)
1200 mA
IMB-dc1 (
DC voltage converter for input voltages 9 – 32 V DC
)
1200 mA
IMB-acc (
Accumulator module for portable units
)
1200 mA
