The PDI® TFA Static Transfer Switch maximizes the availability and reliability of power for mission-critical loads through the automatic seamless transfer from two independent power inputs in an innovative True Front Access Enclosure.
Available in sizes ranging from 250A – 1200A, the PDI® TFA Static Transfer Switch maximizes the availability and reliability of power for mission-critical loads through the automatic seamless transfer from two independent power inputs in an innovative True Front Access Enclosure.
Known for its patented transfer algorithms, the PDI® TFA STS is unmatched in its 2 million hour Mean Time Between Failure (MTBF), Dual Redundant Operator Interfaces, Flash Memory Firmware Updates, and Hot Swappable Control Logic Components. The True Front Access enclosure allows for installation, service, maintenance, and IR scanning from the front of the unit – a first in the industry.
The PDI® TFA STS is adaptable for Primary (480V) and Secondary (208V) topologies by utilizing a common power and controls pass through on the PDI® STS and PDU enclosures simplifying installation. The PDI® STS also monitors power quality of both sources including real-time waveform capture and monitoring of downstream sub-feed and panelboard breakers through the 10.4” touchscreen display. Compartmentalized power, SCR, controls, and communications compartments decrease the risk of arc flash and increase worker safety. Adaptable top/bottom entry/exit for power and communications (BMS/DCIM) enables flexible deployment in a wide variety of mission-critical facilities.
PDI® TFA STS redefines performance, reliability and its innovative approach to installation and service ultimately achieves the lowest total cost of ownership for your mission-critical facility.
