PSU rating
Power supplies conforming to the new European standards are specified differently from
older designs. The following information will give a rough indication of how to compare the
current availability figures for new power supplies. The “New Rating” current can be drawn
from the PSU even when the standby batteries are flat.
Example: an EN compliant power supply rated at 1A is able to provide 1A to the system eve
with flat batteries connected and the mains supply at its minimum rating. To achieve this, a
1A power supply could have an overall rating of up to 2.7A depending on the batteries
allowed.
Current available
To meet the relevant standby durations for PD6662, it is important that the current taken
from the power supply does not exceed the figures in the table below. To meet the
requirements of EN50131-1, the figures below must be divided by 2.2 (e.g. 1.5A becomes
0.68A).

Note: in both the above tables, it is assumed that the system transmits a “Mains Fail”
event to the ARC. If it does not, the required standby time is doubled, thus all the
available current figures must be halved.
