Altronix MAXIMAL77 – Frequently Asked Questions

1) Does the Altronix MAXIMAL77 access power controller run on standard 120V building power?
It runs off standard single phase 120VAC line power, so it wires into a normal 115/120V branch circuit in the electrical room or IT closet. Output is low voltage DC for access control field devices, so the only high voltage work is the feed into the enclosure.
2) How much DC current does the Altronix MAXIMAL77 deliver for locks and access control devices?
Roughly 9A of DC output is available across the unit. Budget it against the actual draw of your devices: maglocks and electric strikes pull the most, and continuous duty locks should be counted at their holding current, not their inrush. If your load list lands near that ceiling, split it across two enclosures rather than running the supply at its limit.
3) I only need to power one or two electric strikes. Is the MAXIMAL77 overkill?
For a single opening it is. At around 9A of DC capacity it is sized for multi door systems. For one or two devices, a small regulated supply such as the Securitron AQD1 at 12/24 VDC 1 amp, the SDC 632 Series 2 amp, or the Von Duprin PS902 at 2A 12/24 VDC field selectable is the right size. Step up to the MAXIMAL77 when you are feeding a whole bank of doors from one cabinet.
4) What should I use instead of the Altronix MAXIMAL77 if I only need to power one or two electrified locks?
The MAXIMAL77 is a 120V input access power controller built for high output count and 9A class current, which is more capacity than a single opening needs. For one or two devices, single-output supplies include the Securitron AQD1 switching power supply at 12/24 VDC 1 Amp, the Command Access PS1 at 24VDC with 1 amp output, and the SDC 620 Series 1 amp regulated and filtered supply with dual voltage selection.
5) Is the MAXIMAL77 a commercial grade access power controller or something for a house?
This is commercial equipment, meant for access control systems in commercial and institutional buildings, not residential doorbell or gate duty. It combines power supplies with a fused output controller in one enclosure, which is what a security integrator uses to feed a bank of doors from one place.
6) What is the difference between the Altronix MAXIMAL77 and a plain power supply like the RCI DKPS-2A?
Capacity and scale. The RCI DKPS-2A gives eight outputs at 12/24VDC but only 2A total. The MAXIMAL77 is a power controller with integrated supplies rated around 9A, so it carries far more doors and more current hungry devices from one cabinet. If you are wiring a handful of low draw strikes, the smaller unit does the job; if you are feeding maglocks or a large door count, size up.
7) We want one enclosure feeding every door in the building. Does the MAXIMAL77 support that kind of standardization?
That is what it is built for. It is an access power controller with the supplies built in, sold for commercial installations, so a facility can centralize lock power in one cabinet and distribute fused low voltage runs out to the openings. For a facilities or MRO buyer, that means one product line to stock spares for instead of a scattering of small plug in transformers at each door.
8) I need battery backup with my access control power - does the Altronix MAXIMAL77 compare to supplies sold with backup?
The MAXIMAL77 is built around two AL1024ULXB supplies feeding 16 fuse protected 12/24VDC outputs at 9.7A from a 115VAC 60Hz 5.2A input. Alternatives that state battery backup in their description include the Adams Rite PS-1 regulated power supply at 1 amp 12/24 volts DC with battery backup, the Command Access PS204/204B linear supply with 2A at 24VDC and battery backup, and the Detex 10-800 universal logic controller with 120VAC/24VDC power supply and battery backup. Those are single or low amp units, so they fit far fewer devices than the MAXIMAL77.
9) What looks like a substitute for the Altronix MAXIMAL77 but will not do the same job?
Several items in the same power family serve different purposes. The ROFU 9126T is a plug in mini power supply at 12 VDC 1.5A with time delay, the Command Access CAT Field Tester is a portable 12-24VDC supply that runs off DeWalt, Makita and Milwaukee batteries, the ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V rather than a supply, and the Securitron BPSS is a boxed solar power supply. None of those distribute 16 fuse protected 12/24VDC outputs at 9.7A the way the MAXIMAL77 does.
10) If my spec sheet names a Von Duprin or Aiphone power supply, how does the Altronix MAXIMAL77 differ?
The MAXIMAL77 is a 120V input access power controller rated 9A with 16 fuse protected 12/24VDC outputs. The Von Duprin PS902 is a base power supply at 2A, 12/24 VDC field selectable for access control and is listed as Grade 1. The Aiphone AC-PS1250 is a UL Listed 12V DC 5A supply for AC Series access control kits and is single voltage. Where a drawing calls out a brand-matched supply for a specific device family, match the callout; the MAXIMAL77 is the choice when many fused outputs from one enclosure are wanted.
