Frequently Asked
Questions
Q.
Which products of yours have the sine wave tracking/active
filter? What does sine wave tracking do, is it just a
filter built into a normal Surge Protective Device (SPD)
that filters out high frequency noise on the sine wave?
A.
Any of our AC power products can be ordered with true
sine wave tracking. Sine- wave tracking is also available
on some DC models. The term true sine-wave tracking simply
means that the sine-wave tracking unit will keep an A-1
ringing transient, as identified by ANSI-IEEE, below the
peak of the sine-wave when tested with 6" of lead
length. The sine-wave tracking components act as a filter
and suppress the ring wave transient. The active circuitry
of the sine wave tracking unit will also attenuate undesired
electrical disturbances such as EMI and RFI. The end result
is that the protected equipment will see a purer sine
wave. The sine-wave tracking unit will still clamp threshold
voltages. A margin of safety is provided as per ANSI/IEEE
UL/CSA (see spec sheet enclosed, category B3/C1). All
Advanced Electronics products can be ordered without sine-wave
tracking since it is not required or needed on all applications
(i.e. main entrance panels).
Q.
What do the lights on the front of the unit indicate?
A.
If the indicator lights are off it indicates
that the unit is no longer working. If a unit is installed
in a remote area, monitoring the device may be necessary.
We have taken this into consideration. All our AC panel
models can be ordered with N/O dry contacts. Other monitoring
options are also available.
Q.
What is your standard warranty on all your products?
A.
Our standard warranty on all products is 25 years. Even
if destroyed by lightning!
Q. How many suppression components are in the
Advanced Electronics products?
A.
Advanced Electronics, Inc. makes use of a variety of well-known
and widely used suppression components. These include,
but are not limited to inductors, capacitors, resistors,
metal oxide varisitors, zener and suppression diodes,
and other proprietary elements and combinations thereof.
All components in the products are coated in our unique
Environment Protective Coating (EPC). The compound enhances
the already superior performance of the units.
Q.
Does The Advanced Electronics SPD Use Printed Circuit
Technology
A.
Yes, Another time and field proven technology is printed
circuits. Advanced Electronics uses printed circuit boards
in its products. Meticulous engineering goes into each
printed circuit board. The circuit boards are not typical
computer type boards, as some may believe. In the development
of the circuit boards our Engineers combine principles
of high current, high voltage, high power and RF circuit
board design. Using these engineering principles, we are
able to reduce circuit impedance resulting in low let-through
voltage and higher peak surge current withstand capability,
providing greater equipment protection.
Here are some facts. Some of our printed circuit traces
contain the equivalent copper weight of 6 AWG wire. The
traces are mounted on a substrate of UL94-V0 fiberglass
material. The Advanced Electronics design approach gives
the products their ability to achieve extraordinarily
low let-through voltages and outstanding voltage and current
performance by reducing the circuit impedance.
A troublesome concern for some is an opinion that printed
circuits are weak. Quite the contrary, with better reliability
and longevity, many power supply companies use printed
circuits to carry hundreds and even thousands of amps.
The resulting reliability and longevity are evidenced
in the products. Advanced Electronics does not experience
printed circuit board failures. Surge suppression components
will fail before the circuit cards during destructive
transients.
Compared to bus bar technology, printed
circuits have significant advantages. The use of a bus
bar requires some type of mechanical connection (a bolt,
nut or rivet, etc.) to connect the TVSS components. Mechanical
connections deteriorate over time, especially in industrial
environments where mechanical vibration is expected. A
familiar example: Electricians are often called to "tighten"
panel board connections. Loose connections within a TVSS
unit will dramatically and adversely affect that unit's
performance. Loose connections increase internal junction
impedance. An increase in junction impedance will increase
junction temperature further contributing to the loose
connection problem because of thermal cycling. Additionally,
an increase in junction impedance causes an increase in
let-through voltage performance leaving the equipment
attached to the panel more vulnerable to transient damage-exactly
what the TVSS device was intended to prevent.
By using printed circuit technology, TVSS circuits inside
the devices are permanently mechanically connected and
metallurgically bonded by use of solder. Internal junction
impedance is kept to a minimum and remains consistent
for the life of the unit because of printed circuit technology.
There is never any need to "tighten" any TVSS
part inside a Surge Protection Device (SPD).
Q.
Is The Product Warranted Against Lightning Strikes?
A.
Yes our warranty does include lightning strikes.
Q.
How Does The Advanced Electronics SPD Work?
A.
When a transient voltage appears upon any combination
of conductors which exceeds the preset activation level
of the SPD, the suppression circuitry activates in less
than one nanosecond. Upon activation, the suppression
circuitry creates "temporary bond" above the
peak of the sine wave (preventing "crowbar effect"
or shorting of the power supply) between all of the combinations
of conductors affected by the transient. While the suppression
circuitry is activated, the transient energy is diverted
away from the protected load, reflected back toward the
transient source and converted into heat by the Surge
Protection Device (SPD). The transient energy which the
SPD converted to heat is transferred harmlessly through
the electro-chemical compound to the surrounding air,
instead of damaging protected equipment. The Advanced
Electronics Suppressor is equally effective on positive
and negative transients.
Q.
Will The Advanced Electronics SPD Reduce Our Electric
Bill?
A.
No, there will be no measurable difference in your electrical
consumption following a surge protection installation.
There will, however, be a noticeable difference in your
repair and maintenance cost of protected electrical equipment.
