AC Industrial Voltage Stabilizer for the Rural Area

AC Industrial Voltage Stabilizer

A voltage stabilizer used in rural area is a device that can solve the voltage fluctuation caused by long distance transmission of the electricity.

Advantages:

1: Wider voltage regulation range.

2: Every phase can be regulated individually.

3: Special structure can be easily installed on the pole.

4: Long application life free of maintenance.

5: Can be remote control without local monitoring.

6: Over-voltage, under-voltage, overload, phase loss., short circuit and the bypass protection can protect equipment from voltage fluctuation.

Main function

Over-voltage and under-voltage protection

When output voltage over or under rated voltage value, equipment will automatically trip

 

Over current protection

When the over-current exceeds the rated value, the input will be cut off automatically

 

Mechanical protection

When the voltage regulating operation exceeds the region, the adjustment will be automatically terminated

 

Overload protection

Once overload, it will automatically cut off the power

Main function

Short circuit protection

When the load short circuit, it will automatically cut off the power supply;

 

 Bypass function

 Can be manually switched to mains supply the during the maintenance

 

 Return function

When the sampling voltage exceeds the set value, the power supply automatically returns to normal

 

Display function

LED display

Optional function, extra charge

Phase sequence protection

when phase sequence is reserve or less, it will automatically protect

anti-surge performance

the input terminal is equipped with a high-energy surge impulse suppressor, which effectively solves the fatal impack of the pulse spike voltage between 10μs-100μs, such as lightning induction on the euip.

wave filtering performance

Equipped with a sensitive tracking filter device at the input, which can effectively filter and absorb the pollution signals generated by the inductive load disconnection and the electric field and magnetic field on the line, and strictly control the impact of harmonics on digital equipment;

 

remote communication

 RS485 communication interface (communication protocol provided)

Product characteristics

 true effective value sampling

High accuracy, good sensitivity, good measurement rate and frequency characteristics, hig input impedance , low output impedance, wide power supply range, low power consumption

 

 Vacuum dipping paint

 high insulation strength, good mechanical properties, low noise, corrosion resistance and long service life

 

control chip

The MCU control chip adopts the original imported industrial-grade 32-bit interface ARM chip produced by STMicroelectronics, which has the advantages of strong anti-interference ability, high computing speed, and high-precision AD acquisition.  Digital circuit control, reliable and intelligent operation.

Application field:
