The Vevor variable transformer provides adjustable AC output from 0V to 130V for precise voltage control in home, office, industrial, and laboratory applications. Its 500VA capacity and 3.84A maximum output current make it suitable for powering and testing a range of electrical devices. Built-in protections include fuses, a thermal control switch, and a resettable overload protector for safer operation. An analog dial and top-mounted adjustment knob make voltage changes easy and accurate. The metal housing is designed for durability and heat dissipation.
