SWING-SESL-H-3P-S

> View Input Voltage Swings

In situations where there is a reasonably good mains supply, a Stabiliser 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 Stabiliser.

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.

  Output Voltage:

Presettable for any voltage between 380/220V, 400/230V or 415/240V (Customer to Specify) – Three Phase, 4 Wire (3 Phase + Neutral + G/E).

The permissible input voltage window is relative to the pre-set output voltage.

  Output Voltage Accuracy:

± 0.5%, ± 3% or ± 5% - auto selection based on input voltage swing

  Frequency:

47 to 65 Hz

  Response Time:

< 1.5 ms

  Correction Time:

A 10% supply variation will be corrected to within 2.5% in 0.6 seconds.

  Efficiency:

98%

  Power Factor:

Any Lagging to 0.95 leading

  Surge Ratings:

10 x max current rating for 2 seconds

 

3 x max current rating for 1 minute

 

2 x max current rating for 5 minutes

  Surge Suppression:

TVSS - Protects loads against high energy Spikes and Transient Voltages

  Total Harmonic Distortion:

 < 1%

  Independent Phase Control:      

Maintains each phase voltage stable irrespective of load unbalance, even up to 100% load unbalance.

  Soft-Switch-On:

Ensures the output voltage is set to a minimum upon Switch-On before commencing stabilisation - protects load equipment from damaging start-up voltage surges.

  Input Swing Redundancy:

Parallel Redundant Voltage Regulation Control    Modules (VRCM) on each phase. Should one Module fail or malfunction the other parallel Module will operate automatically without causing interruption to the load and also without affecting capacity.

Introduction

SESL-HD-3P-S Series - 200 to 1500 kVA
Three Phase 3 Wire (No Neutral) AC Voltage Stabilisers

3P 4W Solution

Input / Output:  380V, 400V & 415V AC -  50/60Hz


Our larger International / European voltage Three Phase 3 Wire (No Neutral) Stabilisers specifically configured for the needs of larger site applications. Ideal for over 95% of all general commercial and industrial applications.

Standard Permissible Input Voltage Window Options

SWING-SESL-HD-3P-S

> View Input Voltage Swings

In situations where there is a reasonably good mains supply, a Stabiliser 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 Stabiliser.

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.

 US Voltages

SESL-H-3P-S-X468 Series - 200 to 1250 kVA
Three Phase Servo Electronic AC Voltage Stabilizers

3P 4W Solution

Input / Output:  440/254V, 460/265V & 480/277V AC -  50/60Hz


Our larger US industrial voltage Three Phase Stabilizers specifically configured for the needs of larger site applications. Ideal for over 95% of all general commercial and industrial applications.

Standard Permissible Input Voltage Window Options

SWING-SESL-H-3P-S-X468

> 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 Stabilizer to accomodate and the more accurate the voltage you require on the output, the more expensive the Stabilizer. 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.
