POWER LINE IMPEDANCE STABILIZATION NETWORK MOOEL 3925/2 OPERATING INSTRUCTIONS The Model 3925/2 Power Line Stabilization network Is a two channel low pass Filter network designed to Isolate an electrically operated device from an external power source so that high frequency conducted measurements may be made In accordance with certain electronics standards. The High Frequency Section of this device Is nominally designed for a 25 ampere maximum load capacity with a maximum voltage drop of 2.5%. The low frequency section is nominally rated at 15 amps (10% voltage drop) although the unit will handle 25 amps with a substantial voltage drop (18-20%). Overload protection is provided by a two pole 25 ampere circuit breaker located on the rear panel. The allowable AC line frequency is DC-62 Hz and maximum line to ground voltage Is set at 220 VAC and line to line at 440 VAC. Line side of the PLISN should be connected to the power source with the three pin receptacles located on the rear panel. Three socket plugs are provided to make the necessary connections. Load side of the unit should be connected through the Type ”N" receptacles of the desired channel. The ground connector located on the rear panel should be connected to a safety ground. If a ground contact to the instrument under test Is made to the power source ground. It should be made the ground terminal (socket receptacle or ground stud) on the front panel. No radio frequency isolation Is provided at this terminal and connection Is made directly to the chassis of the PLISN. There are two BNC type coaxial connectors for each line. There Is one for higher frequencies and one for lower frequencies. The BNC type coaxial connector of the line under test and the frequency range of Interest should be connected to the field Intensity meter or spectrum Analyzer Input. The other three BNC receptacles must be terminated with a 50 ohm termination. It Is advisable to connect the input terminals to their proper power source and load before connecting the line under test to the measurement Instrumentation, otherwise It Is possible to damage the mixers or attenuators or the test Instrumentation due to power'surges. Again, when the power Is to be disconnected, remove the measurement Instrument at the coaxial receptacle before removing the power source.
