Data Centers

OnFILTER Filtered PDU Press Release.jpg

One of the key parameters for data centers operation is their uptime. Transients on power lines can easily cause interruptions in operation, data loss, and even equipment damage.  Conventional surge protectors don't do adequate suppression transients, enabling several hundred volts spikes to get through to the servers - please see this page.  OnFILTER' CleanSweep® AC EMI filters not only very effectively suppress EMI on power lines and ground; they are very good in reducing high transient spikes down to very low levels.  They use a different approach than regular surge suppressors - instead of relying on MOV (metal oxide varistors) that utilize voltage levels for suppression of transients, CleanSweep® AC filters treat these spikes as EMI which they are well-equipped to handle; plus the filters are free from typical MOV fatigue rendering MOVs ineffective after some time in service.

Special rack-mounted filtered CleanSweep® power distribution units (PDU)  provide a combination of advanced multi-stage surge protection and highly-effective EMI filtering in both power and ground.

​

CleanSweep® filters and PDUs also block power-line communication (PLC) which may serve as a back door into the servers, enhancing data security of the data centers.

​

Our special ground EMI filters assure EMI-free grounding throughout the data center.

What is EMI?  NIST defines EMI as "“an electromagnetic disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics/electrical equipment.” Most conventionally, EMI is understood as undesirable high-frequency signals, and EMI filters as devices that suppress such signals while preserving the "good" ones.
