STS 16
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 single connection, 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.
Considering its advanced design, the price of the Pulsar STS 
is highly competitive compared with the 'dual power supply' 
options available from suppliers of computer equipment. 1U 
high, the unit can be installed easily within the rack. Five LEDs 
indicate the status of the sources and the STS. 
Designed to provide redundancy as close as possible to the 
equipment, the Pulsar STS deploys a ‘break before make’ 
technology based on relays:
A simple and complete mimic diagram displays the various 
status of the sources and the Pulsar STS. An 'STS COM' 
communication port of the dry contact type indicates the status 
of the sources and the Pulsar STS:
Both sources (primary and secondary) are connected, in a very 
straightforward manner, to the STS in the base of the rack. The 
Pulsar STS then controls the redundancy of this electrical power 
supply. If the primary source fails,transfer to the secondary 
source is automatic and instantaneous.
Redundancy
Simple and cost-effective
Reliability
Associate communication
With the Pulsar STS 16, power from 2 independent sources 
can be supplied to servers and circuit equipment which only 
have one input power supply
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
