Commercial Facilities are at even greater risk of power quality events like transient surges and harmonics because of the number of highly sensitive electronic-based devices. ACT Surge Protection devices in a fifteen-year study with a major retail chain have shown a reduction in electrical lightning repairs by 70%, and also reducing HVAC service calls by over 35%. 

The ACT Family is designed to protect all phases and modes against transient surges and limited overvoltage events and, with the Advanced Power Filter selected, is able to reduce induced high-frequency noise by over 50 dB across a broad frequency spectrum.

With our Power Quality Meter option, we can add Power Quality Diagnostic information with Transient Snap Shot, Time Stamp Data Logging and Wave Form capture. No other SPD company is offering this breadth of power filtering and monitoring capability in a single package.
