ROFU 9102-12D UL/9102-24D Power Supply, 10/120VAC, 60Hz Input

Two output configurations. The 9102-12D UL gives 12 VDC at 2.0 amps; the 9102-24D gives 24 VDC at 1.0 amp. Both run off 110 VAC, 60 Hz line power. Note this is not a field-selectable dual-voltage unit, you pick the voltage when you order, so size the board to the locks you are feeding before you buy.

It depends on the current draw. The 12 VDC board has 2.0 amps to give, the 24 VDC board only 1.0 amp. Add up the holding current of every device on the circuit plus inrush on strikes, and stay under that figure. One 24V maglock or a couple of 12V strikes is comfortable; a bank of doors is not. For a larger load look at the Altronix AL1024ULACMCB, which is rated 24VDC at 10A across 8 PTC outputs, or the Securitron AQS1210 at 12 VDC 10 amp.

Match it to the lock hardware, not to preference. Electric strikes and most standalone keypads run 12 VDC, and the 9102-12D UL covers those with 2.0 amps of headroom. Delayed egress hardware, electrified exit devices and many maglocks want 24 VDC, which is the 9102-24D at 1.0 amp. The two are separate part numbers, so there is no jumper to move after the fact.

The ROFU 9102 is a 110 VAC 60 Hz input supply with a 12 VDC 2.0 A or 24 VDC 1.0 A output. If the opening has to hold up through a power loss, the Adams Rite PS-1 is a regulated power supply, 1 Amp, 12/24 volts DC with battery backup, and the Command Access PS204/204B is a linear power supply with 2A at 24VDC and battery backup. The Detex 10-800 Series pairs a universal logic controller with a 120VAC/24VDC power supply and battery backup.

The ROFU 9102 covers both voltages across its two versions - the 9102-12D UL at 12 VDC 2.0 A and the 9102-24D at 24 VDC 1.0 A, from a 110 VAC 60 Hz input. If you want a single unit that is field selectable between the two voltages instead of picking a voltage at order time, the Von Duprin PS902 is a base power supply rated 2A at 12/24 VDC field selectable for access control, and the Securitron AQD1 is a switching power supply at 12/24 VDC 1 Amp. The SDC 620 Series is a 1 Amp regulated and filtered low voltage supply with dual voltage selection.

The ROFU 9102 is a general purpose 12/24 VDC access control supply at 2.0 A and 1.0 A respectively. Motorized latch retraction draws a heavy inrush and is normally fed from a supply built for it: the BEST RPSMLR2 Series is a power supply for motorized latch retraction exit devices. For delayed egress hardware, the BEST PS161-6 is a 120V input, 12/24V output supply with 6A capacity.

The 9102-12D UL is rated 12 VDC at 2.0 A, so a bank of strikes or maglocks that draws past that needs a larger supply. The Aiphone AC-PS1250 is a 12V DC 5A UL Listed power supply for AC Series access control kits, and the Securitron AQS1210 is a switching power supply at 12 VDC 10 Amp. The Securitron AQL4 is a switching supply rated 12/24VDC at 4/3 Amp if you want headroom on both voltages.

The 9102-24D delivers 24 VDC at 1.0 A. Moving up at the same voltage, the Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC output and boost circuitry, the SDC 632 Series is a 2 Amp regulated and filtered low voltage supply with dual voltage selection, and the SDC 634 Series is the 4 Amp version. For much larger loads the Altronix AL1024ULACMCB is a power supply and access power controller with 115VAC 60Hz input at 4.2A and 24VDC at 10A across 8 PTC outputs.

The 9102-12D UL is UL Listed. If the job spec calls for a listed supply at other ratings, the Aiphone AC-PS1250 is 12V DC 5A UL Listed, the Command Access PS210 carries UL 6E/CSA at 1.5A 24VDC, and the Von Duprin PS902 is a Grade 1 base power supply rated 2A 12/24 VDC field selectable.

No. The ROFU 9102 requires a 110 VAC 60 Hz input, so it needs line power at the location. Where there is no AC run, the Securitron BPSS is a boxed solar power supply. If you only need to power a device temporarily at the door to test it, the Command Access CAT Field Tester is a 12-24VDC portable power supply compatible with DeWalt, Makita and Milwaukee batteries.

Count amps, not doors. With 2.0 amps at 12 VDC you have a real budget to divide among devices; at 24 VDC you have 1.0 amp. Also note this is a single-output supply, so if you need individually fused or PTC-protected runs to separate openings you will want a controller-type board instead. The RCI DKPS-2A gives 8 outputs at 12/24VDC 2A, and the Altronix AL1024ULACMCB gives 8 PTC outputs at 24VDC 10A.

The ROFU 9102 is a power supply - it takes 110 VAC 60 Hz in and puts out 12 VDC at 2.0 A or 24 VDC at 1.0 A. Several items that come up alongside it also switch or manage that power rather than just producing it: the Altronix AL1024ULACMCB is a power supply and access power controller with 8 PTC outputs, the RCI DKPS-2A is a power supply with 8 outputs at 12/24VDC 2A for access control systems, the SDC 631 Series is a 1.5 Amp regulated and filtered DC power controller, and the BEST ELR150 Series is a power supply control module. The Detex 10-800 is a universal logic controller with its supply built in. If you need multiple independently protected door outputs, a multi-output unit does that; the 9102 feeds its output directly.

The ROFU 9102 is a 110 VAC 60 Hz input DC supply offered at 12 VDC 2.0 A and 24 VDC 1.0 A. The comparable set splits by conversion type: the Securitron AQD1 at 12/24 VDC 1 Amp, the AQL4 at 12/24VDC 4/3 Amp and the AQS1210 at 12 VDC 10 Amp are switching supplies, while the Command Access PS1 Series 24VDC 1 Amp, the PS204/204B and the PS210 are linear supplies. The SDC 620, 631, 632 and 634 Series are described as regulated and filtered. Which one you specify usually follows what the lock or reader manufacturer calls for on its wiring sheet.

Commercial. The 9102 is built as access control infrastructure for commercial openings, and the input is 110 VAC 60 Hz line power hardwired into an enclosure, not a plug-in wall transformer. Expect to mount it in an electrical or IT closet and pull line voltage to it, which is licensed electrical work in most jurisdictions.
