Binary logic of digital processors operates on strings of 1s and 0s based on very rapid fluctuations of low voltage – relative to the equipment ground. Very small ground line power disturbances are significant to those digital processors and can mimic actual logic signals causing a computer (e.g. DSP) to incorrectly interpret data.The semiconductor industry published recognized guidelines on the maximum levels of normal mode and common mode (ground) power disturbances that should be present in the semiconductor environment. Their guidelines clearly state that power disturbances up to those described in ANSI-IEEE C62.41 (maximum 6000 volt) must be reduced to less than 10.0 (ten) volts for line – neutral (normal mode) surges and 0.50 (one-half) volt for ground (common mode) surges.
Several products on the market are capable of reducing normal mode problems. But, the only way to limit power disturbances on the ground to the recommended levels is with an isolation transformer or other specialized power conditioner. Ordinary surge protection devices, even so-called “series mode” devices, do not have that capability.
Since we represent Juice Goose, we will introduce you to what Juice Goose offers to combat the issue of voltage on the ground. The PowerVar series is an Isolation transformer and UPS, all in one box.
Here are just a few of the features of this product series:
Key power conditioning features of the Security II series include:
| A | Power Surge Diverter |
| B | Isolation Transformer |
| C | Power Line Filter |
| E | Battery Backup |
These components combine to limit normal mode (line to neutral) surges to 10 volts. Common mode (ground line) surges are limited to 0.50 volts.
