Maintenance
The power supply and stand by battery(s) should be tested at least once a year as follows:
1. CHECK
LED’s for normal state
: AC ON Green, Trouble Normal ON Green, DC ON Red.
2. CHECK output voltage with normal load (assures proper voltage to float charge batteries): For 12V setting, voltage should
read between 13.6 VDC and 13.8 VDC; and for 24V setting, voltage should read between 27.1 VDC and 27.6 VDC.
3. DISCONNECT AC input: AC LED should be off, and
all other LED’s should remain normal.
4. CHECK DC output to be above 12.0 VDC for 12V setting and 24.0 VDC for 24V setting (checks standby batteries to be
operational).
5. APPLY AC and VERIFY AC LED ON.
Battery Selection
The table below shows typical standby time in hours for various loads and batteries. The table works for either 12 VDC or 24 VDC.
The AQD6 was evaluated at UL with a 75 Ah sealed lead acid battery.
