Product Description

Non-contact Compensating AC  Industrial Voltage Stabilizer

model :ZSBW  (three phase) ,   ZDBW (single phase) 

According to the change of the input voltage of the power grid line, the analog signal of the changed voltage is transformed into digital signal through sampling by the voltage detection unit, which is processed by microcomputer, preprogrammed program and prefabricated data. The intelligent control system sends commands to the optocoupler to drive the non-contact and fast electronic switching circuit to compensate the output voltage appropriately and accurately, so as to adjust the output voltage within the allowable error of accuracy, so as to achieve the purpose of automatic voltage stabilization.

Performance characteristics:

 

 

Fast response

12Bit high-speed AD acquisition, 128 wave acquisition points per cycle, digital processing and operation by single chip microcomputer, and rapid compensation by electronic module

Multiple adjustment modes can be set

Simultaneous regulation: when simultaneous regulation is set, AD simultaneously collects the true effective values of three-phase voltages a, B and C for average calculation, and gives instructions for compensation, which can effectively improve the imbalance of three-phase voltage

Individual regulation: when individual regulation is set, the three-phase voltages are adjusted respectively to ensure that the three-phase voltages are within the accuracy range, especially suitable for single-phase load

Automatic judgment: microcomputer automatic analysis should carry out simultaneous or individual regulation.

Advanced measurement technology

12Bit AD acquisition, digital filtering and true RMS calculation by single chip microcomputer

Accurate control

Perfect cooperation between large-scale programmable logic device and single chip microcomputer

Humanized Interface

Various indicators (output voltage, voltage stabilizing accuracy and protection function) can be set through the touch keys on the operation panel

No distortion of output waveform

Contactless zero crossing switch switching, same frequency, phase locking and sine wave superposition compensation principle

Resistance to harmonic interference

True RMS voltage detection

Wide load range

Resistive, capacitive and inductive loads can be adapted

Slow start and impact resistance

voltage stabilization first before output

Full protection function

In case of overvoltage and undervoltage, it can be protected within 1s or automatically switched to bypass without interruption, and has perfect phase loss, overload, short-circuit protection and sound alarm function after fault
