Automatic voltage stabilizer

PDX compensation type automatic voltage stabilizer consists of compensation transformer, regulating transformer, transmission mechanism, electric brush contact system, as well as box and simulation control system. It has stepless voltage regulation, stable output, no wave distortion and no harmonic increment.

The product has 1% to 5% adjustable accuracy as well as ±10% to ±50% compensation range. Its capacity 10 to 1800 KVA respectively. In addition, its efficiency can reach more than 96%. The product is stable and reliable, and comes with all the power protection function.

Compensation and regulation products adopt a ring-shaped disk type under 30KVA and the three-phase wich is all adjustable. In contrast, compensation trasformer uses E type product while regulating product adopts winding cylinder type wich is above above 50KVA. The three-phases is adjusted uniformly and can also be adjusted based on users' requirements.

The transmission mechnism of the product is composed of servo motor and sprocket chain. Its power on mode consists of automatic mode and manual mode. When the output voltage is greater than the rated value, the voltage stabilizer can automatically bypass or cut off the output and then send out sound and light alarm.

Circuit structure and working principle

PDX automatic voltage stabilizer consists of compensation voltage circuit, sampling circuit, output control and bypass circuit. Compensation voltage stabilizing circuit, control circuit and sampling circuit form automatic compensation voltage-stabillizing system.

CONTACT TYPE VOLTAGE STABILIZER

Arakawa introduce PDX series which is the best contact type voltage stabilizer today. it's differ with common voltage stabilizer. it have many advantages as the result of long R&D. it has stepless voltage regulation, stable output, no wave distortion and no harmonic increment. PDX series are the best choice for low total cost of ownership for heavy duty voltage stabilizer for all application.
Arakawa Power Stabilizer are designed for ease of installation and maintanance, with simple but secure wiring system.

ADVANTAGES

PDX Series are the best contact type voltage stabilizer. It resuited from more than 20 years solid experience in contact type voltage stabilizer continuous research and development as the result:
Fast regulation (Automatic)
Response times less than 1.5s to stable the output voltage which common type stabilizer need 7 second to complete the regulation.
Over and under voltage protective
When the Output line voltage exceed peak or below lowest, several seconds delay, the machine automatic turn into "By Pass" mode, at themean time, the value of input voltage equals to the output voltage, Buzzer alarm continuously and the yellow indicator is illuminated.
Fault protection
When the regulator component generates failure, regulator will automatically switch to bypass or cut off the output and send out sound and light alarm. The value of input voltage equals to the output voltage, Buzzer alarm continuously and the yellow indicator is illuminated.
Phase loss and phase sequence protection
When the three-phase output power produces phase-lack of fault phase, regulator will automatically cut off the output voltage.
Highest Compensation
Highest compensation can reach ±50%. The highest compensation of traditional stabilizer just reach ±30%.
High Efficiency
The efficiency can reach more than 96%. The highest efficiency of traditional contact type stabilizer are below 96%.
High Quality Purefied Power
Regulation process without wave-distortion and power-off wich is applied to computer and precision electronic equipment.
Safety
With Lightning-Proof and wave-filter function, depresses surge and filter harmonic waves.
