DH910 Tri-Volt Wired Doorbell Transformer Ideal for Two Chimes

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.

Use One Transformer for Multiple Low-Voltage Doorbell Jobs

The DH910 tri-volt doorbell transformer is useful when you need flexibility across 8V, 16V, and 24V low-voltage doorbell applications. Contractors and maintenance teams can use it as a replacement doorbell transformer for different chimes, bells, or buzzers without stocking separate transformer models for every voltage.

What to Verify

Match the output to the device: check whether your chime, bell, or buzzer needs 8V, 16V, or 24V before wiring. Also confirm the load requirement, especially when powering two low-voltage devices from the same transformer.
