DynaLock 5225 Series, Open Transformer, 120VAC/24VDC, 2 Amp

Yes, within its rating. The 5225 takes 120VAC input and puts out 24VDC at up to 2 amps, so it will power a maglock or strike drawing 2 amps or less at 24VDC. Add up the holding current of every device on the circuit before you size it, since 2 amps is the maximum, not a per-device allowance.

DC. The 5225 is the 24VDC version, with a built-in rectifier bridge on the secondary. Other models in the DynaLock 5200 Series are built with 12 or 24 volt secondaries in either AC or DC, so pick the model that matches the device you are feeding. A DC maglock will not hold correctly on an AC supply.

The DynaLock 5225 is an open transformer with a 120VAC input and a 24VDC output rated at 2 amps, with the rectifier bridge built in. If the device you are powering runs on AC rather than DC, the MS Sedco 12024 is an open frame 24V AC transformer that steps 120V down to 24V and mounts with screws. Both are open frame units meant to be mounted inside a cabinet or enclosure rather than plugged into a receptacle, so the swap is mainly a question of whether your lock, strike or detector wants DC or AC at the terminals.

The DynaLock 5225 is an open frame transformer supplied with color-coded flying leads, so it is intended to be hard wired and mounted inside an enclosure or box. Where there is a convenient receptacle and no box, the Trine 5204 is a plug-in type transformer with a 12VAC output, and the Trine 5205 is a plug-in tri-volt AC transformer that lets you select among its output taps. Those give you AC only; if the device on the door needs DC, stay with the 5225, which outputs 24VDC through its built-in rectifier bridge.

No. The Trine SR-1 is a silicon rectifier, not a transformer - it converts AC to DC but does not change 120V line voltage down to low voltage. The DynaLock 5225 does both jobs in one device: it takes 120VAC input and delivers 24VDC at up to 2 amps with the rectifier bridge built in. An SR-1 is what you add downstream of an AC-output transformer, such as a plug-in AC unit, when the load needs DC. If you buy the 5225 you do not need a separate rectifier.

Open frame means the 5225 ships as a bare transformer with no housing or cover. It comes with 10 color-coded flying leads for wiring. You supply the enclosure or backbox, so plan on mounting it inside an access control cabinet or junction box where the leads and primary connections are protected.

No. The 24VDC models in the DynaLock 5200 Series, including the 5225, have the rectifier bridge built in, so DC comes straight off the secondary. You would only add a separate unit like the Trine SR-1 silicon rectifier if you were converting the output of an AC-only transformer.

The 5225 puts out 24VDC at 2 amps from a 120VAC primary with a rectifier built in. The MS Sedco 12024 is an open frame 120V to 24V AC transformer with screw mount, so its output is AC, not DC. Use the MS Sedco where the device accepts AC, and the DynaLock where the lock or strike requires DC.

Only if the combined draw stays at or under 2 amps at 24VDC, which is the maximum rating for the 5225. Two typical maglocks on one supply can exceed that, so total the current for every device on the run first. If you are over, split them across separate transformers or move to a larger supply.

Both are open frame transformers fed from a 120V line, so both get mounted inside a cabinet, panel or box rather than hanging off a receptacle. The difference is the output: the DynaLock 5225 delivers 24VDC at 2 amps with the rectifier bridge already inside, while the MS Sedco 12024 delivers 24V AC and mounts with screws. Standardize on the 5225 where your maglocks and electrified hardware call for DC, and on an AC unit where the devices are AC coils or AC-driven sensors.

Commercial. The DynaLock 5200 Series is catalogued for commercial electronic access control work, feeding low voltage power to locking devices where an economical power source is wanted rather than a full supervised power supply with battery backup.
