Reader Supply Current
There is a maximum of 200mA available per reader channel on the 18V supply. PAC Portico readers of all
types draw approximately 90mA each continuously. If you fit Alarm Modules or AEMs, a reader combiner
or Wiegand interface unit, ensure that the maximum current available, 800mA, is not exceeded.
In the table below record a current consumption for each device fitted:
Channel

Reader Current 1
35mA (see Note 1)
Reader Current 2
100 mA (see Note 2)
Wiegand/Magstripe
Reader 50 mA

Table 2 Total Reader Channel Current
Notes
1. Reader current 1 applies to the standard plus, slimline readers and vandal resistant reader MKII
(flying lead) (15 mA idle, 35 mA active).
2. Reader current 2 applies to the low profile reader, vandal resistant reader MKI (terminals) and
panel mount reader.
3. When using a reader combiner, you should include the current of the combiner in its column plus
the total current for both readers in the reader column.
4. Only include a value for the reader current if the Wiegand reader is powered from the Wiegand
interface unit’s 5V output or the 18V reader supply.
5. Include 40mA for each AEM that is connected to a reader channel.
Total Power
The door controller itself consumes 1A before the addition of any readers or locks.
For each 100mA of reader channel current, as determined above, an additional 150mA should be
allowed. This is due to several factors involved in the generation of the 18V dc supply.

Note
The above figures are all stated in Amps, 1A = 1000mA.
