Product Description

 ZSBW, ZDBW three-phase, single-phase intelligent and purified no-contact compensating alternative stabilizers are new products combining the most advanced technology abroad with our national condition. It uses micro-program process, light and electrical transmission, no-contact switch, compensated alternative stabilizing technology, and has advantages of high efficiency, energy saving, quick adjustment, no noise, no connected spot, anti-interference, auto adjustment  according to each phase, full function, high reliability, long life, free of maintenance. It's also equipped with RS-232 interface and can realize promote control and test.
This series is widely used in the places requiring stable voltage such as communication equipments, broadcast and TV stations, in dustrial production line, digitally controlled machine, textile industry, medical equipments, hotels, computer rooms, etc.


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
Voltage and current display	The true RMS values of voltage and current are displayed on the touch screen
