Trine 5205 Transformer Plug-in Type/Tri-Volt (AC)

Yes, on the 24V option. At 24VAC the 5205 delivers 20VA, .83 amps, and electric strikes are one of the loads it is built for along with bells, buzzers, chimes and other low voltage devices. Add up the draw of every device on the circuit, not just one strike, and keep the total under .83 amps at 24 volts. Note the output is AC, so a strike or lock that requires DC needs a DC supply instead.

It is a plug-in type transformer that goes straight into a 120 volt receptacle, with all primary leads pre-stripped for quick connection on the secondary side. If your install calls for an open-frame unit screwed into a box or a can rather than an outlet, that is a different form factor: the DynaLock 5212 Series is an open transformer at 120VAC/12VAC 2 amp, and the MS Sedco 12024 is an open frame 24V AC screw mount converter. Choose by where the power is available at the door.

The Trine 5205 covers 8VAC, 16VAC, and 24VAC and does not include a 12 volt tap. For a 12VAC device, the DynaLock 5212 is an open transformer rated 120VAC to 12VAC at 2 amps. Choose by the voltage the strike or buzzer actually calls for: the 5205 if it is 8, 16, or 24 volts AC, the 5212 if it is 12 volts AC.

The Trine 5205 is a plug-in type, so it goes into a 120 volt receptacle and its primary leads come pre-stripped for connection. The DynaLock 5212 and the MS Sedco 12024 are open frame units - the MS Sedco 12024 is a screw mount 120V to 24V AC converter. An open frame transformer is meant to be mounted and hard wired, typically inside an enclosure or a can above the door, so the choice comes down to whether you have a receptacle at the location or are running line voltage into a box.

Use the MS Sedco 12024, an open frame 24V AC transformer that converts 120V to 24V and screw mounts, which suits hard wiring into a box or enclosure. The Trine 5205 also delivers 24VAC, but it is a plug-in type that occupies a 120 volt receptacle, so it fits openings where an outlet is already within reach of the strike run.

The body measures 2 inches D by 3 inches H by 2-1/2 inches W, so it needs a receptacle with roughly that much clearance around it. Because it plugs in rather than mounting to a surface, plan on an outlet within cord reach of the strike, typically above the frame or in the adjacent closet or ceiling space.

It takes itself offline. The 5205 shuts down safely when it overheats, which is what protects the winding on a continuous-duty condition like a strike held energized or a buzzer button stuck closed. That is a thermal cutout, not a resettable breaker you flip, so the fix is to clear the fault and let it cool before expecting the door to work again.

Only if the total draw stays inside the tap you bought. The ceiling is 1.25 amps at 8VAC, .62 amps at 16VAC, and .83 amps at 24VAC. Intermittent-duty strikes that fire briefly are a different load picture than anything held energized, and multiple doors on one supply is where installers overrun the VA. If the arithmetic gets close, run a second transformer or move to a higher-amperage supply such as the DynaLock 5313 at 3 amps for a DC system.

On the 16V option, yes, provided the old unit was also 120 volt primary and your chime draws no more than .62 amps at 16VAC. The 5205 is a plug-in with pre-stripped primary leads, so if the existing transformer was hard-wired into a junction box you will need an outlet at that location or an open frame screw-mount unit instead. Confirm the voltage stamped on the old transformer, because chimes, buzzers and strikes on the same building are often on different taps.

The Trine 5205 is a tri-volt commercial unit with 8VAC, 16VAC, and 24VAC secondaries, and it is rated for electric strikes, bells, buzzers, chimes, and other low voltage devices, so one part number serves openings with different voltage requirements. The DynaLock 5212 and DynaLock 5313 are each fixed at a single output - 12VAC and 12VDC respectively - and the MS Sedco 12024 is fixed at 24VAC. Fixed-output units suit a facility already standardized on one voltage; the 5205 suits a mixed fleet.

No. Both are plug-in units, but the DynaLock 5313 outputs 12VDC at 3 amps, while the Trine 5205 delivers AC at 8, 16, or 24 volts. Matching the plug-in mounting style does not make them interchangeable - a 24VAC strike needs the 24 volt AC output, so the 5205 is the part for that opening.

Commercial. Trine catalogues the 5205 as a commercial installation accessory for low voltage door hardware, though the load list, bells, buzzers and chimes alongside electric strikes, is exactly the range a multi-family or apartment entry intercom draws on. Property managers replacing a burned-out entry transformer on a buzzer system are in the right place.
