Technical Specifications

The THE 115 VAC/HIGH ENERGY SURGE SUPPRESSOR combines in one unit the low clamping voltage and high surge current capabilities needed to protect solid state power and electronic systems from severe lightning-induced and other over-voltage surges. This suppressor meets the need for low clamping voltage and exceptionally high surge current capability packaged in a single, small size unit. Until now these capabilities have been available only from large hybrid protectors comprised of multiple components. The suppressor is packaged to withstand rugged airborne and ground-based environments and will clamp repetitive high energy transients. It is designed for use in a wide variety of applications.

THE 115 VAC/HIGH ENERGY SURGE SUPPRESSOR operation has been verified for single pulse capability and multiple pulse (multiple stroke) environments. This assures the suppressor will provide protection in the multiple stroke lightning environments for aluminum structures (6 x 70 μs wave-form), all composite structures (50 x 500 μs wave-form), and mixed structures (40 x 120 μs wave-form).

THE 115 VAC/HIGH ENERGY SURGE SUPPRESSOR is especially suitable for clamping lightning-induced surges appearing on aircraft 115 volt AC power distribution busses feeding solid-state avionics. The suppressor clamps the high energy surges to levels easily tolerated by most solid state power supply inputs without interruption of power or tripping of circuit breakers. Its surge current capability exceeds that of many spark-gap devices, and its response (“turn on”) time is virtually instantaneous. The suppressor meets applicable requirements of RTCA DO-160, US MIL-STD-704, and most other aircraft power quality specifications.
