Installation Instructions
Current Loading
Power drawn from the Securitron B100 subtracts
from the power available from the Securitron AQL
supplying the Securitron B100. The most accurate
way to determine the draw from the Securitron
AQL is to calculate the actual power draw and
factor in the efficiency of the Securitron B100.
PI = PO*1.15
Where:
PI = Input power of the Securitron B100
PO = Output power draw on the Securitron B100
Current Load Examples
Example 1 What size Securitron AQL power supply do you need to create
a dual voltage power supply system providing 24 V at 2 A and 12 V at 2 A?
1 Determine current load: 12 V x 2 A = 24 W x 1.15 = 27 W | 24 V x 2 A = 48 W
2 27 W + 48 W = 75 W current load
3 Find Securitron AQL power supply rating: 144 W for AQL6 | 240 W for AQL104
4 Use a Securitron AQL6 or AQL104 to meet the system’s power needs
Example 2 An Securitron AQL4 is powering a Securitron B100.
The Securitron B100 is set for an output of 12 V and has 3 A total load
connected. How much power is available from the Securitron AQL4?
1 Determine current load: 12 V x 3 A = 36 W x 1.15 = 41 W
2 Find AQL power supply rating: 48 W for the Securitron AQL4
3 Subtract current load from power supply rating: 48 W – 41 W
= 7 W available from Securitron AQL power supply
Example 3 What size Securitron AQL power supply do you need to create
a dual voltage power supply system providing 24 V at 4 A and 5 V at 2 A?
1 Determine current load: 5 V x 2 A = 10 W x 1.15=11 W | 24 V x 4 A = 96 W
2 11 W + 96 W = 107 W current load
3 Find Securitron AQL power supply rating: 144 W for AQL6
4 Use a Securitron AQL6 to meet the system’s power needs
Max Power Available 12 V 24 V
Securitron AQL4 48 W 72 W
Securitron AQL6 72 W 144 W
Securitron AQL102 120 W
Securitron AQL104 240 W

Remove all AC and battery power from
the Securitron AQL system before adding
or replacing a Securitron B100 board.
Observe polarity of the DCIN and
BR Connections or damage to
the system could occur.
The DC In, DC Out, and BR terminals run
through the board for daisy chaining
and each terminal set is interchangeable
from a functional standpoint.
Either DC IN may be used, either
DC Out may be used or either BR
may be used interchangeably.
