DynaLock 5313 Series, Plug-in Transformer, 120VAC/12VDC, 3 Amp

Output type is the whole difference. The 5300 Series is built with secondary outputs in 12 or 24 volts, AC or DC, all rated 3 amps maximum; the DC models carry a built-in rectifier bridge. The 5313 is the 12VDC one. Pick a DC model when the lock, strike or controller wants DC (most maglocks and many electric strikes do), and an AC model when the device is AC only. Running an AC-only strike on DC, or a DC lock on raw AC, is how coils get cooked.

The Trine 5205 is a plug-in tri-volt AC transformer, meaning one unit covers more than one AC secondary voltage instead of committing you to a single output. The DynaLock 5313 is a fixed 120VAC/12VDC 3 amp unit. For a service truck or a retrofit where the strike voltage gets confirmed at the opening, the tri-volt Trine 5205 gives you the selection on site; for a specified 12VDC device with a 3 amp draw ceiling, the DynaLock 5313 is the single-purpose part.

The MS Sedco 12024 is an open frame 120V to 24V AC transformer with a screw mount, so it fastens into a can, cabinet, or junction box and is hard-wired rather than plugged in. The DynaLock 5313 is a plug-in unit intended for locations where a standard 120VAC convenience outlet sits close to the device being powered, with screw terminals provided for the field hook-up on the secondary side. Where the specification or the facility does not allow a cord-and-plug source at the door, the screw-mount MS Sedco 12024 is the mounting style to ask for. Note the output difference: the MS Sedco is 24V AC, the DynaLock 5313 is 12VDC.

Screw terminals are provided on the 5300 Series for field hook-up, so you land the low voltage conductors directly on the transformer. Nothing to solder and no pigtail to splice. On the 5313 those terminals are 12VDC, rectified at the transformer by a built-in bridge, so polarity matters at the lock end.

For 24V, ZenSupply carries the MS Sedco 12024, an open frame 24V AC transformer that converts 120V to 24V and mounts by screw rather than sitting on a plug. Trine's 5205 is a plug-in tri-volt AC transformer if you want to select the output voltage at install. Both are AC output; the DynaLock 5313 is the DC choice at 12 volts.

Three amps at 12VDC is the ceiling on the 5313, so add up the continuous current draw of every device on that circuit and stay under it. A pair of maglocks pulling half an amp each leaves plenty of headroom; a bank of doors will not fit. Also remember each 5313 needs its own 120VAC outlet nearby, which usually decides the layout before the amperage does.

Two things separate them for a facility standard. Output: the DynaLock 5313 is 120VAC/12VDC at 3 amps with a built-in rectifier bridge, while the MS Sedco 12024 converts 120V to 24V AC. Installation: the DynaLock 5313 is a plug-in unit for openings with a nearby 120VAC convenience outlet, and the MS Sedco 12024 is an open frame screw mount unit for hard-wired installation. A facility running 24V AC strikes standardizes on the MS Sedco 12024; one running 12VDC locks standardizes on the DynaLock 5313. Confirm the coil voltage on the door devices before you set the standard, because the two are not interchangeable at the lock.

Yes, the 5313 is a commercial-rated transformer, part of DynaLock's electronic access control line and intended as a low cost source of low voltage power for access control devices. It is an open transformer, not a sealed or enclosed unit, so it belongs in a protected interior location at an outlet, not somewhere exposed.
