High Performance Beta Range
GreentubeTM HV Series Gas Plasma Arresters
The HV Series is a 2-terminal bi-directional, voltage triggered
switch designed for the protection of high voltage circuits.
Switching voltages for the devices are fixed depending on the
part number selected. The gas plasma trigger technology offers
very fast switching speeds, high current capability and very low
leakage currents.
Features
2 terminal configuration.
Very high Isolation up to the specified switching voltage.
Switching performance is virtually unaffected by changes in
ambient temperature.
UL 1414 class Y2 rated. Listed under file number E56529.
Moisture resistance as per MIL-STD-202 method 106
(90-98%RH, 65C)
Tape and reel to EIA 481-1
Applications
To protect of high voltage circuits.
To provide isolation between chassis and ground.
