NOTE 1. EURO 280 power supplies are NOT designed for use with multiple batteries connected.
NOTE 2. System load should not exceed the panel power supply output shown above, or the maximum load supportable by the battery for the
specified backup time, as in the table shown below.
NOTE 3. The power ratings are based on battery shown in table – but ANY battery capable of supporting the system load for the required time
may be used without affecting these ratings.

Recharge time <24 Hours
EN50131-6:2008 Rated Output
In accordance with EN50131-6:2008, the control panel standby times and effective output currents depend on the Security Grade of the
system and how 230V mains missing fault is signaled to the Alarm Receiving Centre. Power supplies are rated in accordance with the
requirements of EN50131-6, which are related to the maximum battery size that can be accommodated in the housing and vary according to
the grade of the system in which they are installed, as per the following table:
Electrical Capability EN50131-6 Rating. Maximum Load
Example Battery Model Grade 2 Grade 3
Yuasa NP7-12 1.4A 0.9A
EN50131-1:2006+A1:2009 (30 hrs if notified to an ARC) for 17Ah battery = 477mA (Grade 3).
EN50131-1:2006+A1:2009 (60 hrs if not notified to an ARC) for 17Ah battery = 193mA (Grade 3).
