• A guide to Real Power Protection

2
Why Buy Power Protection?

• Because AC Power is the most unpredictable part
  of you system design
• Without AC, you system wont work
• Unregulated AC can subject your system to voltage
  bursts (spikes and surges)
• These can damage your system or cause it to
  operate incorrectly
• Incoming AC voltage can vary.
• This causes your electronics to be starved from
  the voltage they need to operate correctly

3
Why Buy Power Distribution? Continued

• AC noise will cause irritating buzz in your
  system
• EMI (Electro-Mechanical Interference) is caused
  when another device on the same circuit
  introduces noise.
• Refrigerators, Air conditioners, etc.
• The noise could even be coming from the operation
  of your neighbors electronics.
• RFI (Radio Frequency Interference)
• Initial Powering up of our equipment can cause a
  on rush of power can cause a breaker or fuse to
  trip or damage your electronics.

How Do Problems Enter a System?
Normal Mode Phase (hot) to Neutral Should be lt10
volts
Common Mode Neutral to Ground Should be lt ½ volt
5
What Devices Are Used To Solve Power Problems.
Which Device Is The Appropriate One To Use?
6
SIMPLE AS A-B-C
7
AC The Surge Diverter/Filter
Example of surge diverter/noise filter
function. Diverters and filters convert normal
mode to common mode.
8
Remember
Normal Mode Phase (hot) to Neutral Should be lt10
volts
Common Mode Neutral to Ground Should be lt ½ volt
9
B Isolation Transformer
H N/G
H N G
Isolation transformers eliminated common mode
voltage. Transformers provide a code legal way of
bonding neutral to ground.
10
Balanced Power Transformer
H N G
H G N
60 volts
60 volts
Balanced power transformers have their ground
separated from phase and neutral by 60 volts.
Neutral and ground cannot be bonded and common
mode voltage is not eliminated. Balanced power
transformers are primarily designed to eliminate
60 Hz. hum. They are not intended for
microprocessor based electronics.
11
ABC ETA Power Conditioner
H N/G
H N G
When used with a true isolation transformer with
a neutral to ground bond, surge diverters and
noise filters can do their job without creating a
common mode disturbance. The number of surge
diversion and filter elements is also greatly
reduced.
12
So What Does This Mean to Digital Equipment?

• Digital Equipment is very sensitive
• Digital communication is a sequence of 1s and
  0s
• The slightest variance could cause a Errors,
  causing No Fault Found service calls
• Digital Takes a Reference Point from Ground
• If Noise is present on Ground, the reference is
  corrupted and errors result.

13
Remember
Normal Mode Phase (hot) to Neutral Should be lt10
volts
Common Mode Neutral to Ground Should be lt ½ volt
14
An Example of Power Line Noise
Normal Mode Noise - 1.5 volts
Common Mode Noise - 2 volts
15
Remember
Normal Mode Phase (hot) to Neutral Should be lt10
volts
Common Mode Neutral to Ground Should be lt ½ volt
