24VAC Pendant & Accent Lighting Kit
Build a set of vintage-style pendant or under-cabinet lights powered by the 4011F-3 (120V→24VAC, 40VA). Use AC-compatible 24VAC LED modules or add a small bridge rectifier + regulator to run DC LED strips. The transformer’s 40VA rating lets you power multiple fixtures on one unit; mount it in a discrete metal box and add fused outputs and a dimmer compatible with 24VAC for adjustable mood lighting.
Electromechanical Automata with Solenoids
Create kinetic sculptures or tabletop automata that use small 24VAC solenoids and relays for movement. The transformer supplies reliable low-voltage power for timed sequences and can run several solenoids (check coil VA). Pair with a simple microcontroller-driven relay board or cam-timer to sequence motions—perfect for gallery pieces or interactive displays.
Model Railroad Accessory Hub
Turn the transformer into a compact accessory power station for a model railway layout: feed turnout motors, street and building lighting, and accessory relays. 24VAC is commonly used for many layout accessories; use terminal strips, fused circuits, and a few isolated outputs so you can power lighting, point motors and animated features from one stable source.
Automatic Garden Valve & Fountain Controller
Use the transformer to power irrigation/sprinkler valves or small fountain solenoids that require 24VAC. Build a weatherproof enclosure with a dedicated terminal block and relay outputs driven by a timer or microcontroller (with moisture/temperature sensors) to create an automated garden watering or water-feature system. 40VA lets you run multiple valves (verify each valve’s coil current).
