Why should sensitive electronic loads be protected? - To
directly improve your "bottom line"! One study shows failure to
protect sensitive electronic loads is costing American manufacturing,
commercial and service industries over $39 billion per year in lost time and
revenue. The manufacturing industry alone spends 1.5 to 3.0 cents for every
dollar of sales paying for power disturbance costs. Addressing these losses
is a major profit opportunity for your business.
How common are transients? - Low level transient
disturbances (100-1000V) occur on a daily basis and result in equipment
failure over time. Transients over 1000V can result in immediate damage.
Transient Voltage Surge Suppressors are like a
"pressure relief valve" on the electrical system. Although
effective at handling high energy disturbances, TVSS components will not
activate until the disturbance reaches a designated clamping voltage.
A series hybrid filter reacts instantly to changes in
frequency and voltage regardless of phase angle or polarity. In comparison
to other TVSS filters, this technology (inductor/ capacitor circuit combined
with suppression elements) provides a higher level of suppression,
reliability and life expectancy.
Why are electronic loads threatened by power
disturbances? - Advancements in micro processor
technology have resulted in integrated chips that are
smaller and much faster due to more "densely
packed". As a result, sensitive electronic loads:
- Are easily damaged by low level, repetitive
transients (dielectric failure);
- Cannot always operate reliably on the raw power
supplied by the utility or backup generators; and
- Are susceptible to physical damage and
operational upsets (logic errors, software glitches).
This increased level of sensitivity causes electronic
loads to be more susceptible to damage, errors and malfunctioning. Even the
smallest power disturbance can upset the operation of your microprocessor
The effects of noise - Noise disturbances can be
interpreted as legitimate on/off digital signals, resulting in operating
errors and equipment downtime.
To function properly, your sensitive electronic loads
must be supplied with the "clean" power required and recommended
by equipment manufacturers.
Why Do OEMs choose AEGIS? - AEGIS is used by
manufacturers and OEMs that build panels, control systems or
equipment assemblies. Benefits include:
- Reduces costly field service calls to repair or
replace damaged microprocessors and PC boards
- Fewer OEM warranty claims; and
- Improved uptime and system
These benefits far exceed the cost of Aegis TVSS filter

B3/C1 Combination (Impulse) Wave (6000V, 3000A)
AEGIS protect against the full spectrum of transient
disturbances. - AEGIS filters the entire sine wave and
is effective against both frequently occurring low energy
and occasional high energy transients. High energy
transients can create immediate damage, while low energy
transients cause microprocessor failure over time.
Tycor's products are designed in accordance with
ANSI/IEEE C62.41 (1991) recommended spectrum of transient
wave forms. The AEGIS protects against all ringwave and
Let-through Voltages (L-N) - (Based on ANSI/EEE
C62.41, 1991 AND C62.45, 1992)
