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 won’t 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.

4. How Do Problems Enter a System?
Normal Mode
Phase (hot) to Neutral
Should be <10 volts
Common Mode
Neutral to Ground
Should be < ½ volt

5. What Devices Are Used To Solve Power Problems
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
GEAR
Example of surge diverter/noise filter function.
Diverters and filters convert normal mode to common mode.

8. Remember Normal Mode Common Mode Phase (hot) to Neutral
Should be <10 volts
Common Mode
Neutral to Ground
Should be < ½ volt

9. B – Isolation TransformerH 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 TransformerH 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 ConditionerH
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 1’s and 0’s
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 Common Mode Phase (hot) to Neutral
Should be <10 volts
Common Mode
Neutral to Ground
Should be < ½ volt

14. An Example of Power Line Noise
Normal Mode Noise - ~ 1.5 volts
Common Mode Noise - ~ 2 volts

15. Remember Normal Mode Common Mode Phase (hot) to Neutral
Should be <10 volts
Common Mode
Neutral to Ground
Should be < ½ volt
