Circuit Breaker Protection
The Dynastar / International Diamond Series voltage transformers have circuit breaker protection. This built-in technology will turn the transformer off when connected to an electrical device that is too powerful for the transformer. When this triggers, you can simply reset the transformer on models that are larger than 500 watts, while on models 500 watts and smaller, a fuse needs to be replaced.
Extra Durable, Lifetime Rated Coil
Silent Operation
Made with superior quality high end Transformer coils, these transformers are made to be silent. Should not have any humming noises like many of the inferior model transformers.
Thermal Protection
Thermal protection is a protection that gets activated by a fuse inside the transformer converter when it is too hot or overheats. This can happen sometimes when the transformer is overused or used on a appliances that is very close to the max watts of the transformer. We suggest buying a voltage transformer/converter that is at least double the wattage so that this protection doesn’t activate. If you will be using the transformer in a place that is hot, then try using a larger transformer than you normally would for that device. This protection will auto-resolve when the transformer cools down.
High Temperature Protection
High temperature protection is a protection that is in the transformer that will activate the fuse or circuit breaker when the transformer reaches a high temperature. This feature activates when the temperature is too high. This can happen when the appliance or electronics used on the transformer are very close to the max watts and the transformer is overworked. Once it reaches a high temperature, it will automatically shut down. This can be resolved automatically when it’s back to a normal temperature or by pushing the circuit breaker switch.
