POWER LINE IMPEDANCE STABILIZATION NETWORK
POWER LINE IMPEDANCE STABILIZATION NETWORK MOOEL 3925/2
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
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.
