> View Input Voltage Swings

In situations where there is a reasonably good mains supply, a Stabilizer offering an input variation swing of  ±10 % or ±15% (S10 / S15 Models) will usually be more than acceptable, but in more remote locations, or countries where the national supply infrastructure is less developed, variations of ±20% or greater may be needed to be accommodated by the Stabilizer.

TIP - The wider the permissible input voltage window you wish the Stabiliser to accomodate and the more accurate the voltage you require on the output, the more expensive the Stabiliser. So, when selecting the most appropriate and cost efficient model for your application, it pays to know the state of the utility mains supply on site and the designed input voltage tolerances of the load equipment you wish to protect.

MVSI-X468 Input Voltage Window

> View Input Voltage Swings

In situations where there is a reasonably good mains supply, a Stabilizer offering an input variation swing of  ±10 % or ±15% (S10 / S15 Models) will usually be more than acceptable, but in more remote locations, or countries where the national supply infrastructure is less developed, variations of ±20% or greater may be needed to be accommodated by the Stabilizer.

TIP - The wider the permissible input voltage window you wish the Stabiliser to accomodate and the more accurate the voltage you require on the output, the more expensive the Stabiliser. So, when selecting the most appropriate and cost efficient model for your application, it pays to know the state of the utility mains supply on site and the designed input voltage tolerances of the load equipment you wish to protect.
