Option Definition |
Unit of Measure | |
|---|---|---|---|
| Static UPS | UPS where solid-state power electronic components provide the output voltage. | None | |
| Alternating current output UPS | UPS that supplies power with a continuous flow of electric charge that periodically reverses direction. | None | |
| Direct current output UPS | UPS that supplies power with a continuous flow of electric charge that is unidirectional. Includes both individual rectifier units for dc applications and entire Dc-output UPS frames or systems, consisting of rectifier modules, controllers, and any other supporting components. | None | |
| Unknown | Unknown | None | |
| Standard UPS | Uninterruptible Power Supply (UPS) is a combination of converters, switches, and energy storage devices (such as batteries) constituting a power system for maintaining continuity of load power in case of input power failure. | None | |
| Other | Other | None | |
| Not applicable | Not applicable | None | |
| None | None | None | |
| Modular UPS | A UPS comprised of two or more single UPS units, sharing one or more common frames and a common energy storage system, whose outputs, in Normal Mode of operation, are connected to a common output bus contained entirely within the frame(s). The total quantity of single UPS units in a modular UPS equals Òn + rÓ where n is the quantity of single UPS units required to support the load; r is the quantity of redundant UPS units. Modular UPSs may be used to provide redundancy, to scale capacity or both. | None | |
| Rotary UPS without diesel | A Rotary UPS is where one or more electrical rotating machines provide the output voltage. A rotary UPS that does not contain an integral diesel engine to supply power to the load during an input power failure. | None | |
| Diesel-coupled rotary UPS | A Rotary UPS is where one or more electrical rotating machines provide the output voltage. A rotary UPS that contains an integral diesel engine that may be used to supply power to the load during an input power failure. | None |
