Comparative table  of Three Phases stabilizer between Static Electronics and Servo Motor system 
  

Static Electronics System

Servo Motor System

    It is a stabilizer that design to stabilize voltage by changing Tap of transformer with using Thyristor be as electronic switch to adjust coil of transformer.
It is the stabilizer that design to stabilize voltage by movement of charcoal brush that touch along coil of transformer by use motor to be as a driver.

Respondent time or time for voltage stabilization is very high speed more than all other typ.

Respondent time or time for voltage stabilization is very slow more than all other typ.

Without line disturbance into electrical system when it is stabilizing voltage.

There is line disturbance into electrical system when it is stabilizing voltage, which occurs by arc at touch panel of coil and charcoal brush. From the beginning, it is quite rarely to happen but when using for long time it will more increase line disturbance then affect to damage of instrument, machine or high sensitive electronic equipment that they are connected with stabilizer.

None of any movement and soundless to annoy when it is stabilizing voltage.

There are movement and sound to annoy when it is stabilizing voltage such as motor of driving belt, chain or touch panel of charcoal brush.

There are line conditioner circuit and spike protection for automatic shutdown.

There are no line conditioner circuit and no spike protection, to make damage of instrument, machine or high sensitive electronic that they are connecting for operation.

Able to be well operation with electrical system that there is changing up-down both low and high.

Able to be well operation with stable electrical system or there is a few of changing up-down. If apply to supply with electrical that there is always change up-down to much or frequency,  it will not able to follow up the voltage stabilization and also will be more worn out both at coil and charcoal brush, include other power transmitter system.

It can be operated in many places.

There is a limit for using, just only place such as the place that need to be quiet for working. The place that it has to much minute dust form working, it will be the catalyst of arc at touch panel of coil.

For Three Phase stabilizer, voltage stabilization system of each phase will separate by free control, which it will effect to voltage that pass control to be accuracy by requirement of regulation, even as voltage between Phase and Phase (Line to Line) or Phase and Neutral (Line to Neutral) though voltage that coming of each phase will be different change.  

For Three Phase stabilizer that import to distribute in nowadays, the voltage stabilization system of each phase is not free separate from each other.  If voltage that coming of each phase is different change such as Phase 1 is higher, Phase 2 is normal and Phase 3 is lower, if sensor circuit is set to check Phase 1 then the driver system that use seized axle together, it will stabilize voltage at Phase 1 to be correct but it will effect to Phase 2 and phase 3 to be wrong as consecutive low and lower voltage. Although the sensor circuit is designed the best but if driver system still use seized axle together then voltage that pass control will not be accuracy in any phase. Therefore if it is necessary to use stabilizer of Servo system, it must be the control system that free separate of each phase, which it is better but then the price might be higher also.

Suitable application with electronic equipment or machine that control by computer, including all kind of high technology equipment.

Unsuitable application with electronic equipment or machine that control by computer, but suit to apply with light system, cooling system or general electric appliance.

Easy maintenance.

Need more especially maintenance such as need to clean around surface of coil that it will touch with charcoal brush, need to change charcoal brush when it has worn-out, need to clean and lubricate for chain, gear wheel, ball bearings that they do function as a power transformer. (if there are)    

Long-life durable using.

Short-life and un durable using and depends on the condition of operation. Such as voltage condition that it has more or less change, load type that take to connect for using, which it has electrical system supply by stability or instability, the dust in working, include frequency of maintenance.

Available repair, modification or devices change. 

Difficult repair or modification such as when arc occurs at coil of transformer, it can not repair but it need to change all set and wait for spare parts from abroad.

All internal devices are standard quality, be as high grade devices, well known and reliable brand name such as Magnetic Contactor of Hitachi, Circuit Breaker of Mitsubishi.


Internal devices are unknown brand name and unknown origin place.

Reasonable price, designed and made in Thailand by
SILICON POWER SUPPLY CO., LTD.

Little cheaper price, the majority import from China.
