Power Distribution, Inc. (PDI) has announced the 1200A WaveStar® TFA (True Front Access) Static Transfer Switch (STS). Breaking the notion that “bigger is better” while keeping the same mold, PDI’s latest innovation retains the same 800 AMP STS footprint and boosts power load transfers for mission-critical facilities to 1200 AMPs. Following suit with its WaveStar TFA family of products, the new 1200A STS also allows front access to compartmentalized and commonly-accessed electronics to improve worker safety while enabling IR scanning and touch-screen display power monitoring capabilities.

Every data center manager has a different preference for input/output power connections. To meet these flexibility requirements, the new 1200A TFA STS provides the ability to arrange the Molded Case Switch and Power-connections modules to show preference for either Top or Bottom service entrances within the 60” wide by 36” deep cabinet.  Additional features include:

  • Line-and Match with PDIs POWERPAK 2 and POWERHUB 2 Power Distribution Units (PDUs) offer independent customization of both the PDU and STS to offer power switching and distribution unique to each client or facility.
  • Triple Redundancy provides the ultimate in power system reliability.
  • Dual Redundant Operator interface enables operators to select Mode-of-Operation to maximize uptime. When combined with the triple redundancy feature, it offers an industry-leading 2 million hours Mean Time Between Failure (MTBF).
  • Volt Second Synchronization (VSS) Algorithm provides quick power source switching within CBEMA limits, without connecting the two sources, and minimizing voltage disruptions while preserving transformer flux balance.
