14.16 Power Supply

Supply voltage 9 - 14V DC

IRIS 800 – typical current – dialler on hook 145mA (supply at 12v)

IRIS 800 – typical current – dialler off hook 175mA (supply ay 12V)

IRIS 820 – typical current – dialler on hook 165mA (supply at 12V)

IRIS 820 – typical current – dialler off hook 195mA (supply at 12V)

IRIS 850 – typical current – dialler on hook 185mA (supply at 12V)

IRIS 850 – typical current – dialler off hook 215mA (supply at 12V)

Note – on the IRIS 850 there will also be additional transient peak current of up to

250mA required as GSM and GPRS transmissions (e.g. for network registration

and calls) are made.
