Is the Spectra IWM mount available without a power transformer?
IWM Series Mount
The power transformer in the IWM model is not needed for the installation.
The IWM can be purchased with or without the transformer. IWM models that include a transformer are indicated with a '24' in the part number. For example, an IWM-BK would be a black IWM. An IWM24-BK would be a black IWM with a 24VAC transformer included.
