Pulsar STS

With the Pulsar STS 16, power from 2 independent sources can be supplied to
servers and circuit equipment which only have one inputb power supply.

Redundancy
At present, only top-of-the-range servers are equipped with a dual electrical power supply.

In their original form the majority of these types of equipment - including concentrators, switches, auto-routers, invoicing servers, SMS servers and
middle-of-the range servers - are singleconnection, that is to say they have only
one electrical input supply. With the Pulsar STS, every rack of critical
equipment can be connected to a redundant power supply.

Reliability
Designed to provide redundancy as close as possible to the equipment, the Pulsar STS deploys a ‘break before make’ technology based on relays:

In the event of a short-circuit, the Pulsar STS ensures that the fault cannot affect the alternative source, so that power continues to be supplied to the fault-free equipment,

Power is transferred without overlap of the sources in order to prevent any
node of reliability,

Even if it suffers a fault, the Pulsar STS continues to supply power to the
equipment from the remaining available source.
