Polyphaser dc Injector/dc Path Protectors
IS-MD50LNZ SERIES
DC Path-MW Downconverted Coaxial Surge Protectors
APPLICATION:
80Hz and up Microwave Systems that use Gunnplexers and have 50 to 500MHz lf frequencies with power and/or data or error signals in the dc to 0.5MHz band. Two are required for complete surge protection - one inside the tower top unit and one inside the
hut at the bulkhead panel.
FEATURES:
| Employs UL497B listed gas tube
| Transceive bi-directional to signals
| Isolates and protects standard telco battery power on coax from lightning and transient surges
| Patented design separates the dc from the RF, protects each optimally and recombines them
| Bulkhead mounting/grounding (flange mount adapter)
| Lower throughput energy than dc continuity protectors
(dc type protectors with a gas tube will not handle the
voltage and current for this application without the tube
staying on and destroying itself with the first strike)
| | | | | |
| Not weather resistant
| Weatherize using WK-1
| Multi-strike capability
| NEMP rated
| Aluminum enclosure 18-8 stainless steel hardware
| N silver shell and gold center pin
Mil Specs: Many - call with requirements
TEN YEAR WARRANTY
