This is a switched 24 vac power supply, i.e. not a transformer. Have used it as a substitute for a “C” wire in a Wi-Fi thermostat. Advantage is the small size and cool operating temperature. Since the waveform is not full wave sinusoidal, the typical voltmeter will not record voltage accurately but it does work with a Honeywell Wi-Fi thermostat and associated heating relay.
Worked as advertised.

Just what we needed, easy installation
Low power draw on idle. Measured at 0.15w, which is terrific compared the standard transformer that draws 3w.
90-degree bendGood training clips with a true 90-degree bend. A bit Large, but better too big than too small.
