4000 watt Voltage Conversion Transformer Heavy-Duty Step-up/Step-Down AC 110V/120V/220V/240V Power Conversion, with resettable Circuit Breaker Protection, with US Power Cord, LCD Display

This 4000 watt transformer steps up voltage from 110-120 volts to 220-240 volts. It also steps down voltage from 220-240 volts to 110-120 volts. It offers safe, reliable, steady, economical, and straightforward solutions. [Note]: Electrical appliances with a rated power exceeding 4000W are not supported. It is generally advised to select a unit with a power rating greater than 30% of the appliance's power consumption. The conversion efficiency is 90%. When the input supply voltage is 110V, the maximum output voltage is 230V ± 5V. When the input supply voltage is 220V, a stable output voltage of 110V ± 5V can be obtained. It features 3 American sockets and 3 universal sockets, compatible with plugs from all over the world. It contains a hard-wired heavy-duty insulated power cord and an LCD display that can show input voltage and corresponding fault codes in various situations for simple troubleshooting. It provides overcurrent protection, overload protection, overheating protection, short circuit protection, built-in grounding protection, and sturdy shell protection. Fitted with a resettable circuit breaker. If the unit stops due to overcurrent or overload, press the "FUSE" button on the back to restore the circuit. Note: If a malfunction occurs, you can locate corresponding instructions in the manual based on the fault code displayed on the screen. It features an efficient toroidal transformer for stable output and low power consumption, enabling continuous operation
