The doorbell transformers is step-Reduce the 120 V line voltage to the down transformer at the lower voltage required to use the doorbell.The 120 V voltage in your home is applied to the primary winding or coil of the transformer to obtain a lower voltage from the secondary winding or coil.The old doorbell is provided by a 6 or 8 volt transformer.The newer doorbell works under 12 or 14 v ac.The modern doorbell works under 16 v ac.Replace the transformer with singleCenter-voltage secondaryTap, two voltage secondary or multiple tap, multiple tap-Voltage secondary.All the Bell transformers are step-The down transformer lifts the 120 V voltage to the voltage required for the doorbell being used.A transformer with a fixed voltage secondary reduces the line voltage of 120 volts to 6, 8, 10, 12, 14 or 16 volts.Center-The tap Bell transformer provides dual voltage outputs of 5 and 10, 6 and 12, 8 and 16 or 7 and 14.The old 6 v doorbell will be operated using a 5, 6 or 7 v transformer.The operating voltage of the 8 v doorbell is 7 V or 8 v.The rated voltage of any doorbell is plus or minus 1 volt.Multiple-The tap secondary transformer is a general-purpose transformer that can provide a variety of different voltages.Some taps provide all the nominal voltage for any system you may encounter--6, 8, 10, 12, 14 or 16 volts.
