Static Transfer Switches – How fast do They Switch, In the event of a power loss ?
Power Continuity installations switch seamlessly via STS to the UPS & Generator supplies without any break, to avoid any disruption or loss to your site; virtually instantaneous.
No Break Power Protection. True Power Continuity.
For true resilience, though, there needs to be at least TWO GRID supplies feeding your Data Centre as a bare minimum and preferably these A & B feeds are from two separate ring mains. This is where a Power Continuity Static Transfer Switch (STS) comes into play.
The STS automatically selects the best & most stable available power from either of the two or more available sources, and rapidly switches over; as and when required, simultaneously. Should the STS sense any aberration in the mains supply it will switch. Your supply may not even go onto UPS and yet the STS can sense micro distortions and switch; afterwards switch back to the preferred source. This can happen many times or hardly any. It’s automatic.
How quickly will a Power Continuity STS respond?
It depends on the model of STS you choose.
Power Continuity Static Switches usually respond within around 3 to 5 milliseconds (thousandths of a second) – in fact, so fast that your equipment will not even notice or be affected by the change of power source from Source A to B feed or vice versa.
How is this achieved?
By the use of silicon-controlled rectifiers (SCRs) which, having no reliance on moving parts, allowing the transfer to be made extremely super fast, in fact Power Continuity STS are the most reliable in the industry.
As static switches are so vital to Data Centre resilience, what can go wrong?
PowerContinuity engineers are experienced in installing Power Continuity Static Transfer Switches as part of our complete power protection package.
