About AMETEK Power Quality Solutions
AMETEK Power Quality Solutions (AMETEK PQS) is a manufacturer of surge protection, power conditioning and power management solutions and comprises the ESP (Electronic Systems Protection) and SurgeX brands. ESP was founded in 1985 to protect the then-new integrated circuit technology in multifunction printers; SurgeX technology was originally developed to stabilize the electric field in gel electrophoresis and entered the AV industry in 1995. The product portfolio includes Advanced Series Mode Surge Elimination, Multi-Stage Protection, EMI/RFI filtration, Over/Under Voltage Cutoff, Inrush Current Elimination (ICE), Zero Voltage Switching, sequencers, isolation transformers, UPS solutions as well as diagnostic and monitoring software (SurgeX CONNECT, enVision IC). Applications can be found in pro AV and home theater, IT infrastructure, digital printing/imaging, building automation and smart home; partnerships exist, among others, with Crestron, AMX, Control4, Compass Control and LynTec. The company is part of AMETEK, Inc. and manufactures at its headquarters in Knightdale, North Carolina (USA), in a 125,000 sq ft (approx. 11,600 m²) manufacturing facility with its own on-site engineering. Distribution is worldwide, with dedicated sales teams for North America, EMEA and LATAM.

Technologies & Processes
Advanced Series Mode Technology
Patented inductive/capacitive circuit technology that fully eliminates surge energy rather than diverting it to ground, without ground contamination.
Multi-Stage Technology
Patented multi-stage protection using MOVs, gas discharge tubes, silicon avalanche diodes, EMI/RFI filtration and voltage cutoff.
EMI/RFI Noise Filtering
Filters interference on the power line to safeguard sensitive AV and IT systems.
Inrush Current Elimination
Limits inrush current peaks to protect connected electronics.
Zero Voltage Switching
Switches at the zero crossing to reduce switching stress on connected devices.
Over/Under Voltage Cutoff
Automatically disconnects the load from the mains in the event of over- or undervoltage.
