OT-HJWJL-1209-X Step up or down 5000W 110V Electronic Transformer

With the new series of step-up/step-down transformers, you can convert the voltage from 110 volts to 220 volts, or from 220 volts to 110 volts. The ST-5000 has a maximum rated power 4000W, which is very suitable for home and industrial applications.
Features
Make sure the appliance to be plugged in uses fewer watts than the transformer’s rating. Insert the voltage tap plug (located on the rear of the transformer) into the pair of holes marked “110”. Plug the transformer’s power cord into a source of 110 volts. 220 Volts will be available at the front panel outlet marked “220” volts when the power switch is turned on. Check carefully to be sure no error has been made.
Note: The power of our transformer must be 2.5 times larger than the buyer’s appliance to be used normally
