ROFU 10305-LA/10306-LA Power Transfer Hinge, Tamper Resistant, 1.5A at 42V, Plastic White Finish

That's the job of a power transfer device like the ROFU 10305-LA / 10306-LA. It bridges the gap between the frame and the door leaf so low voltage can reach an electrified lock, strike, or exit device on a moving door without running exposed cable across the hinge side. It's rated 1.5 A at 42 V, which is the ceiling for whatever you run through it.

Yes, so long as the strike draws no more than 1.5 amps. The transfer is rated 1.5 A at 42 V, which covers the usual 12 and 24 VDC access control loads. Check the strike's inrush current, not just its holding current, since that is the number that exceeds a transfer's rating.

No, and they are not interchangeable. The ROFU 10305-LA / 10306-LA only carries power across the frame-to-door gap, it does not generate or regulate anything. You still need a supply feeding it. For that, ZenSupply carries units like the Command Access PS210, a linear supply with 1.5A at 24VDC output, or the Securitron AQD1 switching supply at 12/24 VDC 1 amp. Size the supply to the door hardware, then use the transfer to get that power onto the leaf.

The SDC 631 is a 1.5 amp regulated and filtered DC power controller with dual voltage selection, which matches the 1.5 A rating the ROFU 10305-LA and 10306-LA transfer devices carry. The Command Access PS210 is a UL 6E/CSA linear power supply with 1.5 A at 24VDC output and boost circuitry, also at the same current. If the opening needs more headroom for additional devices on the same run, the SDC 632 is a 2 amp regulated and filtered low voltage supply and the SDC 634 is a 4 amp version, but the current actually passing through the transfer device still must stay within its 1.5 A rating.

No, those are not interchangeable. The Altronix AL1024ULACMCB is a power supply and access power controller in a grey enclosure, taking 115VAC 60Hz at 4.2A in and putting out 24VDC at 10A across 8 PTC outputs. It is head-end equipment that lives in an electrical room or above the ceiling and distributes power to multiple doors. The ROFU 10305-LA and 10306-LA are the in-frame device that moves that power onto the swinging leaf, rated 1.5 A at 42 V. A single AL1024ULACMCB can feed many openings, each of which still needs its own transfer device.

The choice is by conductor count: the 10305-LA has 2 pins and the 10306-LA has 3 pins, with the 10305-LA measuring 2.8 x 0.5 x 0.3 inches and the deeper 10306-LA measuring 2.8 x 0.5 x 1.1 inches, so the 3-pin body needs more depth in the frame prep. A two-wire lock takes the 2-pin; add a third conductor for monitoring or a second device and you are at the 3-pin. On the supply side, the Aiphone AC-PS1250 is a 12V DC 5A UL listed supply for AC Series access control kits, and the RCI DKPS-2A gives 8 outputs at 12/24VDC and 2A for access control systems if you are powering the reader and the lock from one enclosure.

Three things beyond the transfer itself. A low voltage power supply sized to the door hardware, cable from the supply to the frame side of the transfer, and the electrified hardware on the leaf. ZenSupply stocks supplies across the range, from the 1 amp SDC 620 with dual voltage selection up to multi-output panels like the RCI DKPS-2A with 8 outputs at 12/24VDC. Match the supply's amperage to the lock, then confirm it sits under the transfer's 1.5 A ceiling.

Yes. The 10305-LA and 10306-LA mortise into the frame and the door edge, so with the door shut the contacts are between the leaf and the frame and out of reach. That is what makes it tamper resistant compared with a surface loop running across the hinge side.

Motorized latch retraction draws a high inrush at the moment of retraction, and BEST offers the RPSMLR2 series specifically as a power supply for motorized latch retraction exit devices. The ROFU 10305-LA and 10306-LA carry 1.5 A at 42 V, so confirm the retraction current your exit device draws stays inside that figure before specifying them on an MLR opening. For a delayed egress device instead, the BEST PS161-6 is a 120V input, 12/24V output supply with 6A capacity built for that application.

Choose a supply with battery backup on the source side. The Adams Rite PS-1 is a regulated power supply providing 1 amp at 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 is a universal logic controller with a 120VAC/24VDC power supply and battery backup, which suits an opening that also needs logic and timing. The ROFU 10305-LA and 10306-LA do not store energy themselves; they carry whatever the supply delivers, up to 1.5 A at 42 V, across to the door leaf, so the standby capability has to come from the supply you pair with them.

Size the head end for the total door count, then put a transfer device at each opening. The Securitron AQL4 is a switching supply at 12/24VDC and 4/3 Amp, the Securitron AQS1210 gives 12 VDC at 10 Amp, and the Locknetics LP Series comes in 150 and 250 amp ratings with an enclosure. The ROFU 10305-LA with 2 pins and the 10306-LA with 3 pins are the per-door piece, each carrying 1.5 A at 42 V from the frame into the leaf, so the count you order matches the number of doors, not the number of enclosures.

No. The BEST ELR150 series is a power supply control module for electronic access control, meaning it sits in the power path to switch and manage the output. The ROFU 10305-LA and 10306-LA are a mechanical and electrical crossing point that brings power from the frame onto the door leaf, with 2 pins on the 10305-LA and 3 pins on the 10306-LA. A door using an ELR150 to control its lock still requires a transfer device to get the controlled output into the moving leaf.

It's built and specified as commercial door hardware, intended for framed openings with electrified hardware on the leaf. Nothing stops it working on a solid residential door with a mortiseable frame, but the application it's specified for is commercial access control.

The Command Access CAT Field Tester is a 12-24VDC portable power supply compatible with DeWalt, Makita and Milwaukee batteries, so you can energize the lock at the door and confirm it functions before committing to the frame prep for the 10305-LA or 10306-LA. It is a service tool rather than a permanent source; the installed opening still needs a fixed supply such as the SDC 631 at 1.5 amps behind the transfer device.

The Securitron BPSS is a boxed solar power supply, which addresses an opening with no line voltage run to it. Whatever source you choose, the door side is unchanged: the ROFU 10305-LA and 10306-LA still carry the power across from frame to leaf at 1.5 A and 42 V, and the solar system has to deliver within that rating for the devices on the door.

White plastic, one finish only. Since the unit mortises into the frame and door edge, it isn't visible with the door closed, so the finish rarely needs to match the rest of the openings in a building.
