FAQ: How do I determine which line voltage option to order for my power supply?

Some power products use power far beyond the range of typical electronic products, and this makes choosing the correct line voltage option more challenging. Also, power distribution systems, regulations, and connection techniques vary according to local standards. Higher-powered products often require a site electrician to provide the appropriate power distribution, especially for 3-phase power.

Most Keysight power products have field-changeable line voltage, but they may require moving internal jumpers to accomplish the change. Therefore, to ensure that your power product can be put into service quickly, it is important to use care in ordering the product, regardless of whether it is field-changeable.

For detailed information on selecting the correct line cord and line voltage, see Keysight Power Supplies and Electronic Loads. Also, be sure to consult with your site electrician as needed.
