Ashley-Edison Servo Electronic SES Series Three Phase AC Voltage Regulators,

are designed to ensure that, should the incoming mains voltage drift high or low, the

output voltage remains continuously constant. With inbuilt Transient Voltage Surge

Suppression (TVSS), they also protect electrical and electronic load equipment

against, all to common, harmful high-energy surges, transients and voltage spikes.

With over 25 years of unrivalled experience, gained in some of the world’s most

challenging and demanding power environments, SES AC Voltage Regulators &

Stabilizers include as standard many advanced protection and control features - such

as Independent Phase Sensing, TVSS, Input Circuit Breaker, Bypass Control Switch

and Soft-Switch On - which others only offer as expensive add-on options.

AC mains voltage fluctuations

can cause equipment to

behave erratically and

malfunction. Some systems

may even break down due to

these fluctuations, noise or

spikes. Failure to ensure the

incoming mains voltage is

stable and clean, can often

result in costly equipment

repairs.

Cost Efficient Voltage

Regulation with Fast Speed

of Response, High

Output Voltage Accuracy

and inbuilt Energy

Saving Ability.

With tight output voltage regulation of 1%, or better, and high

efficiency, SES Series Three Phase AC Voltage Regulators are

configurable to optimize energy usage and deliver energy cost

savings. Generating no magnetic interference, they are completely

unaffected by Power Factor, or Load and Frequency variations

and are capable of withstanding high instantaneous overloads.

Their compact and quiet nature means these Voltage Regulators

are suitable for indoor use and may be located near to sensitive

equipment.

When looking for affordable durable Quality voltage protection,

the SES Range of AC Voltage Regulators & Stabilizers from

Ashley-Edison lead the market in all respects.

Voltage Stabilizer

In situations where there is a

reasonably good mains supply, a

Stabilizer offering an input variation

swing of ±15% (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.

An output voltage to within ±0.5%

(±1%) of the preset output voltage is

the norm when specifying a Voltage

Stabilizer. However if a lower output

voltage accuracy of ±3%, or ±5%, can

be accommodated by the load

equipment, the input voltage window

can be further widened proportionally.

Given that the cost of the Stabilizer is

linked to the size of the input voltage

range it has to handle, accepting a

lower output voltage accuracy may

prove to be a more cost

efficient

solution than simply opting

for a larger standard

swing model.
