Worldwide, plug and socket patterns are numerous. Instead of warehousing country-specific plugs in large quantities, consider cord sets with country-specific plugs for wall sockets (mains power) on one end, and IEC connectors on the other end. IEC connectors plug into the inlet of an accessory power strip (APS) or power distribution unit (PDU) offering greater versatility without requiring reconfiguration on the customer’s part while opening global markets.
Accessory power strips come in 10A-15A/100-240VAC, and 10A-15A/125-240VAC. The outlet type is Sheet F, and the inlet types are C14s or C20s. They can also arrive with quick-disconnect connector locks, and come with 4-10 outlets as well as a variety of circuit breakers and fuses. The exterior can is powder coated metal for durability, and colors offered are white, beige, and black.
The PDU is a socket strip using IEC 60320 components in a metal enclosure that is larger than an APS, offering up to 12 outlets and is mountable in a 19-inch rack. Interpower PDUs are rated at 16A/125-240VAC, C20 inlets and Sheet F/J outlets. Accepted worldwide, IEC 60320 components have universalized electrical connectivity by integrating country-specific cords with accessory power system products including jumper cords—entire electrical designs are built around IEC 60320 components. The APS and PDU are especially beneficial when there’s insufficient panel space to power up equipment, and where wall outlets are at a minimum.
Using the APS and PDU with Jumper Cords
IEC jumper cords add to the universal IEC design. Plug one end of a jumper cord to the APS/PDU and the other end to an array of equipment or devices. Interpower Jumper cords have currents and voltages ranging from 2.5A-20A/125VAC-250VAC.
“Accessory power is specifying one plug and socket configuration that is accepted globally for connections between equipment systems,” says Dan Ford, Technical Support Specialist at Interpower. “A country-specific mains connection is needed only for the primary power supply connections. This makes it easier to design and build equipment that can be accepted worldwide. The IEC 60320 interconnection system is generally accepted for use throughout the world.”
Interpower cords and components are manufactured in accordance with Interpower’s product quality plan: hipot testing, continuity testing, and ground testing with multiple inspections. “We test more than the standards require for our own benefit,” Interpower Product Development Manager Ron Barnett said. “We do so because it lends better reliability to our design.”
