Rockstone Power Heavy Duty Step Up / Step Down Voltage Converter Transformers are meant for worldwide use for all electronics, heavy duty machines, or household & industrial applications.

For safety reasons, it's recommended to use a Voltage Converter Transformer that's max watts is at least 50% higher than your appliance. For example, if your appliance is rated at 3000 watts, you need to buy a Transformer with a max power of at least 4500 watts or greater to prevent damage from the transformer itself and the appliance being used. Some appliances, such as heating appliances, power tools, motors, laser printers and TVs, require 2-4 times more watts at start up than the printed rated wattage.

The Rockstone Power Voltage Converter Transformer has a safety breaker that shuts down the unit when the voltage is unstable. What could have caused this incident is that buyer connects the transformer to a non-grounded outlet. Non-grounded outlet tends to have bigger fluctuation of power. Also, if the breaker is broken and user continue to use the transformer without replacing the breaker will also cause issue. In the user manual, manufacturer recommends to always use a grounded safety outlet.

The Rockstone Power Voltage Converter Transformer has full range over-current protection through miniature circuit breaker (MCB), MCB is much more sensitive to over current than fuse, the fuse does not sense but MCB does it in more reliable way, it’ll automatically switches off the electrical circuit during abnormal condition of the network means in over load condition as well as faulty condition, as the switch operating knob comes at its off position during tripping, the faulty zone of the electrical circuit can easily be identified, quick restoration is possible by just switching on the On/Off switch.
