This product is one of our basic PDUs. What is a basic PDU? A basic PDU is a dependable, space-saving, cost-effective way to deliver power to wiring closets, server rooms and equipment racks from a UPS system, generator or utility wall outlet. It complements the benefits of a UPS system by adding more outlets than are provided by a UPS to essentially convert a single high-amperage UPS outlet to multiple low-amperage PDU outlets. A basic PDU is the easiest way to distribute facility UPS or generator power to multiple rack loads.
