Altronix MAXIMAL75D – Frequently Asked Questions

1) Is the MAXIMAL75D meant for a commercial access control system or a home setup?
This is commercial-duty gear. The MAXIMAL75D is an access power controller with integrated power supplies, built for distributing low-voltage power to electrified locks, strikes, maglocks and readers across a multi-door commercial opening set, not for a single residential door. If you only need to power one or two devices, a small single-output supply like the Securitron AQD1 or the Von Duprin PS902 is the right scale instead.
2) I need both 12VDC and 24VDC devices in the same closet. Do I have to buy two separate supplies?
Not with the MAXIMAL75D. It is built around two supplies, one 12VDC and one 24VDC, so 12V strikes and 24V maglocks or motorized latch retraction devices can be fed from the same enclosure. Single-voltage-at-a-time units such as the SDC 632 or the Securitron AQL4 are field selectable between 12 and 24V, which means one voltage per box, not both at once.
3) Will the Altronix MAXIMAL75D drive motorized latch retraction exit devices, or do I need a different supply?
Motorized latch retraction draws a heavy inrush and is typically fed by a supply built for it, such as the BEST RPSMLR2, a power supply specifically for motorized latch retraction exit devices. Delayed egress hardware has its own dedicated option in the BEST PS161-6, rated 120V input with 12/24V output at 6A capacity. The MAXIMAL75D is a general access power controller distributing 16 PTC protected outputs at 12VDC 9.5A or 24VDC 9.7A, so match the device manufacturer's inrush requirement before substituting.
4) I only need to power one or two electric strikes, not a whole access control room. What is a simpler option than the MAXIMAL75D?
The MAXIMAL75D is built for large systems, combining an AL1012ULXB and an AL1024ULXB into 16 protected outputs. For a single opening, a small single-output supply is the simpler route: the Securitron AQD1 is a 12/24 VDC 1 Amp switching supply, the Command Access PS1 is a 24VDC linear supply with 1 Amp output, and the Von Duprin PS902 is a 2A 12/24 VDC field selectable base power supply for access control.
5) What is the difference between an access power controller like the MAXIMAL75D and a plain power supply?
A plain power supply just converts AC to regulated DC. The MAXIMAL75D is an access power controller with power supplies built in, meaning it both makes the power and switches it per opening from the access control system, so each door can be released, locked down or fail-safe/fail-secure controlled from one board. Products like the SDC 634 4 Amp regulated supply or the ROFU 9102 are power sources only; you would add separate relay or control logic to switch them.
6) What else could I use instead of the Altronix MAXIMAL75D for a smaller door count?
For a handful of openings, an eight-output board like the RCI DKPS-2A (12/24VDC at 2A) covers the same distribution job at a much smaller current budget. For a single electrified device, the Command Access PS1 at 1A 24VDC or the Adams Rite PS-1 with battery backup is enough. Step up to the MAXIMAL75D when you are powering a full bank of doors from one enclosure.
7) If I need high amperage at a single voltage instead of both 12 and 24 volts, what should I look at instead of the MAXIMAL75D?
The MAXIMAL75D supplies both rails, 12VDC at 9.5A or 24VDC at 9.7A, because it carries both an AL1012ULXB and an AL1024ULXB. If the job is all 12 volt, the Securitron AQS1210 is a 12 VDC 10 Amp switching power supply. If you need mid-range dual voltage, the Securitron AQL4 is a 12/24VDC 4/3 Amp switching supply and the SDC 634 is a 4 Amp regulated and filtered supply with dual voltage selection.
8) I need battery backup on the opening. Does the MAXIMAL75D cover that, or is there another option?
The MAXIMAL75D is built around the AL1012ULXB and AL1024ULXB battery-charging supply boards, which is why it is described as an access power controller with power supplies. On smaller jobs, comparable supplies that state battery backup include the Adams Rite PS-1, a regulated 1 Amp 12/24 volt DC supply with battery backup, and the Command Access PS204/204B, a linear supply with 2A at 24VDC and battery backup.
9) What is a good step down from the MAXIMAL75D for a two or three door retrofit at 24 volts?
For a handful of openings rather than a 16 output board, the SDC 631 is a 1.5 Amp regulated and filtered DC power controller with dual voltage selection, the SDC 632 is a 2 Amp version, and the SDC 620 is a 1 Amp regulated and filtered supply, all with dual voltage selection. The Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC and boost circuitry. Size the choice to total holding current plus inrush on the locks you are feeding.
10) Does the Altronix MAXIMAL75D include access control logic, or do I need a separate control module?
The MAXIMAL75D is an access power controller that takes a 115VAC 60Hz 7A input and distributes 16 PTC protected outputs, so relay logic for sequencing is typically handled by the panel or by a control module. Where a module is wanted, the BEST ELR150 is a power supply control module for electronic access control, and the Detex 10-800 is a universal logic controller with its own 120VAC/24VDC power supply and battery backup.
11) What is a plug-in alternative when there is no room to mount something like the MAXIMAL75D?
Where a wall cabinet will not fit, the ROFU 9126T is a plug in mini power supply rated 12 VDC at 1.5A with time delay, and the ROFU 9102-12D UL/9102-24D runs on 10/120VAC 60Hz input. The Aiphone AC-PS1250 is a UL listed 12V DC 5A supply for AC Series access control kits. These serve one device or a small kit rather than the 16 protected outputs the MAXIMAL75D provides.
