Sdc TR12 Plug-in Transformer 12 Volts Dc Lock Accessory

Product Description

The SDC Security Door Controls TR12 is a plug-in power transformer that converts standard AC wall power to 12 volts DC output. It is designed to supply low-voltage power to electric door hardware, including magnetic locks, electric strikes, and access control devices. The TR12 connects directly to a standard wall outlet, making it a straightforward power source for door security hardware installations. Licensed locksmiths, access control technicians, and security integrators commonly specify this type of transformer when a dedicated low-voltage power supply is required at the door or panel level.

The TR12 is suited for use in both light commercial and residential access control applications. It serves as a convenient plug-in power source where a hardwired transformer or larger power supply is not practical or necessary. Typical installation scenarios include powering standalone electric strikes, magnetic locks, or other 12-volt DC door control accessories in retrofit or new-construction security hardware projects.

Installation Notes

Installation should be performed by a qualified locksmith, security integrator, or access control technician familiar with low-voltage door hardware systems. Disconnect or de-energize all door hardware before connecting or disconnecting the transformer. Verify that the connected load does not exceed the transformer output rating prior to energizing the circuit. Local electrical codes and access control standards should be consulted to confirm compliance for the specific installation environment.
