This wired doorbell transformer may be used as an 8V, 16V, or 24V transformer.  Manufactured by Carlon, a Thomas and Betts company, this transformer will power up to two low-voltage devices; 10VA(watts) for 8 and 16 volts, and a secondary 20VA(watts) at 24 volts.

The Ideal Transformer to Power Two Chimes, Bells, or Buzzers on the Same Transformer.

Small and compact, this product is durable and packs a punch.  The versatility enables contractors to use it in a variety of situations.  Rather than stocking three different voltages of transformers, stock this one and use the setting you need.

Clamp-on style makes mounting easy.  Mount the outer bracket, wire it, and snap it back in the mounting bracket.
