I've two Vibro Graver electric engravers (120V 60Hz) with me. I gave one to a friend who recently moved to another country. He got a step down converter from 220V to 110V but then he noticed the frequency used there is 50Hz. What would the effects of using the device on a 110V 50Hz supply when the device is meant to be used on 120V 60Hz supply.
First, it is important to understand the basics of the available power. 480V 3-Phase power involves three individual legs of power at different voltages, typically designated L1, L2, and L3. Each of these lines is 120V relative to each other, and they sum together to be 480V. When transforming this power to 120V, the goal is to balance out the
To determine the size of the transformer needed, follow the steps below: Note down the load voltage. Next, note down the load current. Multiply the voltage by the current. Divide the result by 1000. The result is the minimum kVA (kilovolt-amperes) for a single-phase transformer.
In a conversion from an American 120V to an American 240V system, you replace the neutral with a 2nd hot leg. In a conversion from an American 120V to a European 230V system, you still have just 1 hot leg, –but it would just carry more voltage, which the motor wires may not be rated to handle. Performing this conversion is ill advised.

Remove the power cord by unscrewing the connections on the terminal block on the circuit board. Then remove the jumper wire from the "Red AC" section. Move the number 10 dipswitch down and that converts it to 240v. Your electrician will then bring in the neutral, 2 hot wires and a ground wire and you are good to go.

This transformer is designed to convert 3-phase 480v to 3-phase 240v to run equipment such as panels, motors, CNC machines, welders, conveyor systems, pumps, printing equipment, fabrication tools, cryptocurrency miners, datacenter equipment, and other business machines. Primary Voltage: 480 Delta. Secondary Voltage: 240 Delta / 120.
