SDC TR24 Regulated 24VDC Plug-In Power Supply
Overview
The TR24 is a regulated 24VDC plug-in power transformer rated at 1 amp output — a straightforward power component for access control systems that need reliable, code-compliant DC voltage distribution. It converts 120VAC wall input to regulated 24VDC via a 6-foot wire lead configuration, eliminating the need for a dedicated power cabinet in retrofit or small-scale networked access control deployments. UL-listed and Class 2 certified, it fits standard institutional and commercial door control architectures where you're distributing power to readers, keypads, or credential processors.
Compatibility
The TR24 outputs 24VDC at 1 amp — a standard voltage across the access control industry. It operates with any 24VDC reader, keypad, NFC/proximity credential system, or door strike controller designed for networked or hybrid access systems. The 6-foot lead termination allows flexible placement near reader power drops or control panels. Confirm your reader or door control device is rated for 24VDC input before deployment; higher-current applications (door strikes, mag-locks drawing sustained draw above 1 amp) require a larger supply.
Installation Notes
Primary input is 120VAC, grounded — requires a standard wall outlet with proper ground connection. The regulated output maintains stable 24VDC even with minor load fluctuations, protecting sensitive credential readers or wireless repeaters from voltage sag. Thermal overload protection engages if the downstream circuit draws sustained current above 1 amp, shutting down the supply until the fault clears. No special tools required for plug-in installation; wire leads connect directly to the control panel or reader power terminals via standard binding posts or terminal blocks.
