STI STI-34107 Multi-Blade 12 VDC Power Adapter
Overview
The STI-34107 is a 12 VDC multi-blade power adapter designed to convert line power into regulated direct current for electromagnetic locks, strike plates, and access control door hardware. This adapter solves the distributed power-delivery problem in commercial security installations where you need reliable 12V output at multiple door points without running separate transformers to each lock. The multi-blade connector format accommodates standard STI lock and strike assemblies, making it suitable for retrofit into existing access control architectures.
Compatibility
The STI-34107 is compatible with STI brand lock and strike assemblies rated for 12 VDC operation. Verify your installed hardware is marked for 12V input before specifying this adapter—mismatched voltage will damage the device or fail to energize the lock. The multi-blade connector configuration aligns with common commercial access control power distribution designs. If your strike or lock uses a proprietary or non-standard connector, confirm mechanical fit with the device datasheet before ordering.
Installation Notes
Mount the adapter in a secure, climate-controlled enclosure—do not expose it to moisture, dust, or temperature extremes unless the mounting location is specifically rated for outdoor use. Keep the adapter clear of high-current loads and RF sources that may degrade regulation. Wire the input according to local electrical code and the power budget of your existing panel. Ensure the output load (total current draw across all connected locks) does not exceed the adapter's rated capacity—check the datasheet for maximum current specification. Ground the adapter frame to building ground before energizing to prevent noise coupling into access control signaling lines.
