This UL-listed power cord adapter is designed for low-voltage home/office setups. It converts a NEMA 5-15P plug into a C14 connector and is ideal for a device's built-in power cord that doesn't match the available outlet. You can use this adapter to connect a computer, monitor, printer or other device with a NEMA 5-15P plug to an AC wall outlet or UPS system with C13 power outlets. You can also connect your C13 printer or monitor to a switched source on your PC, allowing you to turn both devices on and off at the same time.
