Alpha Delta Model ATT3G50 - UHF Transi-Trap Coaxial Cable Surge protectors.
Transi-Trap surge protectors are gas surge arresters designed to protect sensitive electronic equipment from damage due to excess voltage or currents generated by transient phenomena (lightning or static buildup)
These Connector Coaxial Cable Surge Protectors have N Type (N Female) connectors and are rated for 200 watts at frequencies up to 500 MHz.
They are not DC-blocked, so they will pass control voltages in applications requiring the coaxial cable to carry both RF and DC voltage. They may be easily mounted for the most effective grounding with a 1/4-20 bolt or stud (depending on model) in a single hole or as a bulkhead-mount through the grounding panel.
Frequency Range: 0 to 500 MHz
Insertion Loss: <0.1 dB from 0 to 500 MHz
VSWR: <1.10:1 from 0 to 500 MHz
Impedance: 50 Ohms
DC Blocking: None Will pass DC for power and control purposes. Max. DC or peak is 150 volts
Connectors: N Type (N Female)
Firing Point: 350 volts +/- 15% @ <100 v/s <1000 @ 5k v/us rise
Breakdown Voltage: 20 to 30 volts
Surge Current: 5000 A (8/20 us pulse)
ARC-Plug life: >600 Times @ 500 A pulse (field replaceable)
Size: 1 w x 1-1/4 h x .875 Inches
Mounting and Grounding: Single hole 1/4 - 20 x 7/8 stud
Note: These devices are not intended to protect equipment, personnel or structures from the effects of a direct lightning strike as these are unpredictable in strength and vary widely in severity. Direct strikes can cause building damage, including damage to AC connected appliances and equipment induced through AC power lines.
