I have a power supply with an input of 115/230 VAC. There is no wall plug wired to it, just cut wires. I don't have much experience with this. If I wire this to a cord can I plug it into the wall (120 volts)?

berkeman said:Lordy. I just replied in your laser power supply thread. Why are you migrating to dangerous stuff?
But in case you are really interested in learning how to deal with high voltages in a safe way, there are design rules for trying your best to avoid fire hazards and shock hazards. Do you have an idea of what those design rules would be?...

The first would have 4 wires and the second would have 3 wires.
You should be able to work out which wires are which using a multimeter on the "ohms" scale.
As your supply is 120 volts you may be able to use just one of the input windings if the transformer is the first kind.
If it is the second kind, ie with a center tapped transformer, you would use one of the outer wires and the center tap as the two inputs to your primary.
You would open the box and connect to the terminal block where the transformer leads are anchored. Do not attempt to join a new cable to the wires that come out of the power supply.
Follow the same type of anchoring that was used for the original power cord.
Don't touch anything when the power is connected.
To wire a 115/230 VAC power supply without a wall plug, you will need to first determine the voltage and amperage requirements of your specific power supply. Then, you will need to purchase the appropriate wires and connectors to match those specifications. Finally, you will need to follow the wiring diagram provided by the manufacturer to properly connect the wires to the power supply.
No, it is important to use wires that are specifically designed for use with high voltage and high current applications. These types of wires are typically labeled as "high voltage" or "high amperage" and are made with materials that can withstand the electrical load without melting or shorting out.
It is crucial to follow all safety precautions when working with high voltage and high current electricity. This includes wearing protective gear such as gloves and safety glasses, ensuring that the power is turned off before beginning any work, and using insulated tools to prevent electric shock.
No, it is not recommended to use a wall plug from a different voltage for your power supply. This can cause damage to both the power supply and any connected devices, and can also pose a safety hazard. It is important to use the correct voltage and wiring for your specific power supply.
Yes, it is important to ground your power supply when wiring it without a wall plug. This helps to prevent electrical shocks and can also protect your power supply from damage. It is recommended to consult the wiring diagram provided by the manufacturer for specific grounding instructions.
