      Diamond Series Voltage Converters with Regulator

      Ultimate Protection for Your Most Valuable Electronics

      Experience the pinnacle of 110V-220V power transformation technology with our Diamond Series Voltage Converters featuring integrated voltage regulation. These premium transformers represent the absolute best in power conversion and protection, combining bi-directional step-up/step-down capability with advanced stabilization technology that guards against harmful power fluctuations, surges, and brownouts.

      Engineered to military-grade specifications with superior copper coil construction and precision hand-soldering, each Diamond Series voltage converter delivers unmatched reliability in even the most challenging electrical environments. The built-in voltage regulator constantly monitors incoming power, automatically correcting unstable current to deliver clean, consistent electricity that safeguards your sensitive electronics, whether converting from 220V to 110V or 110V to 220V.

      Voltage Superstore's Diamond Series voltage converters come with our industry-leading 5-year warranty and feature multiple layers of protection including thermal safeguards, overload prevention, and circuit breaker technology. These professional-grade step-up/step-down transformers are essential for regions known for unstable power grids including parts of Africa, the Middle East, Asia, and South America.

      Whether you're protecting high-value medical equipment, precision electronics, or irreplaceable devices, our Diamond Series voltage transformers provide the ultimate defense against power-related damage while ensuring flawless operation of your equipment anywhere in the world.


      ***  IMPORTANT - WHEN SELECTING A VOLTAGE CONVERTER, WE SUGGEST THAT YOU BUY ONE WITH 3 TIMES THE WATTAGE OF THE PRODUCT YOU ARE CONVERTING *** 

      Additional Information

      voltageregulator Voltage Regulator: In many countries voltages can fluctuate so much that electronic equipment can be damaged. Protect your valuables from damaging fluctuations with a built-in voltage regulator stabilizer.
      5yearwarranty-5 5-Year Warranty: VoltageSuperstore offers a five-year guarantee with our products. In any repair, parts/labor is fully covered and you only have to pay for shipping.
      CE_Approved_logo_small_7b93afa0-6a2e-4e79-9fff-e1e1777e5581 CE Approved: After thorough quality assurance tests, the trusted CE has approved the quality of our products.
      stepupstepdown_6c9c41ec-c734-4abf-8311-e3ef6152ad93 Step Up & Step Down Converter: These products serve as a step up and step down converter, converting from 110V to 220V as well as down from 220V to 110V.

      Select 220V when stepping down, and select 100V when stepping up. You can use this anywhere in the world.
      universal-plug Universal Socket: All of our models have a universal socket, and some have more than one. Universal sockets take both grounded as well as nongrounded plugs from everywhere in the world.
      fuse-pic Fuse Protected: Our models are also fuse protected. An additional, replacable fuse is included that will automatically shut down the power in the event that the voltage converter is overloaded.
      grounded Grounded Cord: These models include a grounded cord. This will complete the ground from an input socket through to an output socket of a voltage converter/voltage transformer. Since the units have Shuko pins, they can be operated in regions with wall outlets that accept round pins and work fine with grounded and nongrounded power outlets.
