Eaton STS 16 - Critical Power Supplies

Eaton STS 16Source transfer systemPower supply redundancy for single-connection circuitequipment.With the Eaton STS 16, power from 2 independent sourcescan be supplied to servers and circuit equipment which onlyhave one input power supply.RedundancyOnly advanced servers are equipped with a dual electrical powersupply. A majority of network devices and entry-level servers aresingle connection witch means that the only have one electricalpower input. With the Eaton STS, every critical equipment canbe connected to a redundant power supply.Both sources (primary and secondary) are connected, in a verystraightforward manner, to the STS in the base of the rack.The Eaton STS then controls the redundancy of this electricalpower supply.Both sources (primary and secondary) are connected, in a verystraightforward manner, to the STS in the base of the rack.The Eaton STS then controls the redundancy of this electricalpower supply. If the primary source fails, transfer to the secondarysource is automatic and instantaneous.Eaton STS 16Simple and cost-effectiveConsidering its advanced design, the price of the Eaton STS ishighly competitive compared with the ‘dual power supply’ optionsavailable from suppliers of computer equipment.1U high, the unit can be installed easily within the rack. Five LEDsindicate the status of the sources and the Eaton STS.ReliabilityDesigned to provide redundancy as close as possible to theequipment, the Eaton STS deploys a ‘break before make’technology based on relays:• In the event of a short-circuit, the Eaton STS ensures thatthe fault cannot affect the alternative source, so that powercontinues to be supplied to the fault-free equipment• Power is transferred without overlap of the sources in orderto prevent any node of reliability• Even if it suffers a fault, the Eaton STS continues to supplypower to the equipment from the remaining available sourceEATON Product Catalogue1
