HIGH-SPEED, HIGH-CURRENT SURGE PROTECTORS
PMT/UMT (275) Series
DESCRIPTION
CP Clare鈥檚 PMT(275) and UMT(275) Series surge protectors (350-500V and 550-2500V respectively) provide a
high level of protection from high-speed, high-current transient surges. These devices are constructed using a
proprietary semiconductor junction process which results in nanosecond response times combined with peak
current ratings in excess of 20kA.
