SEYAS 500W Auto Step Up & Step Down Voltage Transformer Converter, 110-120 to 220-240 Volts, Soft Start & Full Load, 7x24hrs Continous Run, Circuit Breaker Protection, U.S. Patent No. US9225259 B2
Brand: seyas
Color: black

Automatic Voltage Conversion Technology
In the past, you have to select the input voltage (by the selector) manually. If the transformer not properly set,it could cause damage the transformer itself and the device trying to power off. SEYAS Automatic Voltage Conversion Technology makes the transformer safer and easily use,it can detect the input voltage and convert to the corresponding you need (U.S.Patent No.US9225259 B2.)

100% Full Load Capacity
This latest high level voltage transformer can be used in 110 volt countries and 220 volt countries,It will convert from 220-240 volt to 110-120 volt AND from 110-120 volt to 220-240 volt 50 60 Hz, The Universal 220v Output Socket will accept all types of plugs except the Big South African plug. Provided 100% FULL Load Capacity. Make sure the total starting power does not exceed the maximum capacity of the converter.

Over-Current Protection by Circuit Breaker
There are 2 input miniature circuit breakers(MCB) installed, once an overcurrent or short circuit happens, the MCB will trip off.MCB is much more sensitive to over current than fuse. Unlike a fuse, which operates once and then must be replaced. Thus, it is safer and easy in use.

7x24hrs Continous Run
High efficiency toroidal transformer with stable output and low consumption. With Temperature Rise Test and IEC test report.

Soft Start Function
Safe start with soft-start Function. A soft-start circuit is built inside to prevent an inrush current at the starting moment. Home circuit breaker not trip off.
NOTE: This converter is designed only for European/Asian 220V (Single Phase), and will not Work with American 220/240V (Dual Phase). WARNING: We recommend 3X efficiency factor for high wattage heat producing items such as Air Condition, Welding Equipment etc.

The SEYAS Advantage: Automatic Voltage Conversion Technology (US Invention Patent No. US9225259 B2). Automatic recognizes the input voltage and convert to the correspond voltage. Manual selecting input voltage is no need any more. Auto convert voltage from 110-120 volt up to 220-240 volt or from 220-240 volt down to 110-120 volt. Premium chip delivers efficient performance for transformer.
Multiple Sockets: 3 AC outputs, 1US Standard Socket for 110-120V appliance(s) & 2 Universal Sockets accept all types of plugs except the Big South African plug for 220-240V appliance(s). Patented Wonpro Upgraded Outlets, work well and are secured in gripping plug firmly. The transformer can be used in countries which voltage are 90V～125V or 180V～250V such as US, EUR, UK, JP and more.
Durable Design: 24*7 hrs work time and 100% loading capacity. Provided 100% FULL Load Capacity, Maximum Power Support 500Watt. Premium chip delivers efficient performance for transformer. High efficiency toroidal transformer inside with stable output and low consumption for a safe, cost-effective use. Built-in silence equipment to lower the noise. Work well with super-quiet performance. 380 Joules Surge Protector inside protects your appliances from unstable surges.
Safe and Simple: Simple on/off button with Soft-start Function. A soft-start circuit is built inside to prevent an inrush current at the starting moment. Home circuit breaker will not trip off. There are 2 sensitive input mini circuit breaker installed for overcurrent protection. Once an overcurrent or short circuit happens, the circuit breaker inside will trip off and shutoff the transformer. Reset the transformer by the button on its back, no need to replace fuse.
