5500 Watt Diamond Series Voltage Transformer – Step Down Voltage Stabilizer

5500 Watt Voltage Converter • Step Up & Step Down Voltage Transformer with Voltage Regulator

The 5500 Watt Diamond Series Voltage Transformer with Regulator is built for people who need stable power when voltage levels rise or drop during the day. This Type 5 model includes a built-in regulator that keeps the output steady, making it dependable for gear that needs clean and consistent current. It works for both directions, letting you run 110 volt, 120 volt, and higher-draw 220-volt equipment without worrying about sudden dips or spikes.

The internal coil is made with real copper, and every connection is hand-soldered. This is the same build quality used across the Diamond Series, and one of the reasons this unit holds up well under long sessions. The heavier construction helps it handle strong start-up loads and makes it suitable for devices that need a Step Down Voltage Stabilizer rather than a simple converter.

Choosing the right transformer always comes down to the same rule: pick a model rated two to three times higher than the wattage of your appliance. With that margin, this Type 5 unit can run computers, printers, shop tools, and home equipment that may draw more power when they switch on. The integrated regulator adds another layer of protection by smoothing out unstable lines, especially in areas where electricity changes from hour to hour.

This transformer supports both directions, so it can power 110/120-volt devices in 220-volt regions and run 220-volt electronics in places that supply lower voltage. It includes a hardwired Euro-style plug and works easily in countries across Europe and Asia. The metal housing, fuse protection, and durable cord all reflect a design built for continuous use rather than short, occasional sessions.

As a regulator 220 votls unit, it keeps output stable even in locations where voltage fluctuates often. Whether you use 110-volt, 120-volt, or 220v equipment, the transformer stays steady under load. That reliability makes it a strong choice for anyone who needs long-term performance and a safe way to run sensitive or high-value gear.

This 5500-watt Type 5 model combines solid construction, a built-in regulator, and dependable output in one unit, giving you a transformer you can count on every day.

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 a 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 size, while on 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 to buy a transformer that is at least double the wattage so that this protection doesn’t activate. If you wil be using the transformer in a place that is hot, then try using a larger transformer then you normally would for that device. This protection will auto resolve when the transformer cools down.			✔		✔
Overload Protection			✔		✔
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.			✔		✔
