SBWZ three phase non contact voltage stabilizer is a fast speed automatic voltage regulator based on DSP CPU controlling, fast AC sampling,effective value correction,zero current transition and fast compensation stabilization technology. It consists of the isolation transformer, SCR module, CPU control unit and safety protection ,the perfect combination of SCR switch technology and transformer achieved a real non contact control, safe, high efficient,energy saving and environment friendly advanced design of AC automatic voltage regulator. SBWZ series is ideal for application on electrical equipments such as production lines, lift, automation equipments, laser euipments, industrial robots,medical equipments. air conditioner, all kinds of electrical home appliances and others in factories, transportation system, telecommunication system, railway system, medical equipments, commercial lighting etc.
FAST DSP CONTROLLED CIRCUIT AND DOUBLE SYSTEM SUPPORTED SCR MODULE
1. Three-phase regulation: The output voltage unbalance is less than 1%, ensuring the accuracy of the output voltage of each phase.
2. Super redundancy: The most unique feature of the SBWZ series is its super redundance. in electronics design, redunancy means reliability. With this ideaology, we used double quantity SCR modules to ensure best reliability. meanwhile, we produced the SBWZ series AVR in 1.0 power factor. in other words, 100KVA=100KW.
3. Wide application range: Wide voltage regulation range, can meet the needs of places and equipments with poor power supply grid quality and large voltage fluctuation range. This SBWZ series can be produced with maximum +/-30% input range based on standard rated voltage of 380V/400V/415VAC. with guranteed output precision.
4. High-speed reaction: with reliable fast DSP control unit, it makes the SBWZ series the three phase AVR with most powerful computing capability. which ensures the regulation reaction speed is within 20 milliseconds, and no voltage change is affected for any computer automation, equipment and instruments.
5. Complete protection functions: Fault display and protection functions such as overload, overvoltage, undervoltage, and short circuit are provided to ensure safe operation of the regulator and load.
6. Flexiable Preset function: The user have acess on the control display panel to set the protection values more flexiable than ever.
7.Adaptability: It has strong adaptability to power grid and load, and can reliably and continuously work stably under various harsh power grids and complicated load conditions.
8. No distortion: Adopt current zero-crossing switching technology, no interruption current during the switching process, no surge current, and the waveform is not distorted.
9. Low loss: minimum power loss, no-load loss less than 0.5%, saving customers a lot of electricity.
10. Quite and long life span: Thanks to the usage of SCR control, this SBWZ series neither have noise of the moving carbon brush as in servo motor type AVR, nor clicking noise of the relays as in the relay controlled AVR. The seemless regulation by SCR modules makes its life span much longer than the relay type and servo motor type AVR.
1. Strong overload capability: The whole machine adopts high-quality components, has good performance, can be used continuously under 100% rated load conditions, and can withstand transient (10 millisecond) overload (3 times) without damaging the machine.
2. Reliable bypass function.Bypass function, easy to maintain: It can be switched between “regulation” and “bypass direct power supply”, which is convenient for fault repair.
3. Intelligent and informative display: The smart meter displays the effective values such as line voltage, phase voltage, current and power in real time, clear, accurate and high resolution. The membrane button operation is safe and reliable.
Meanwhile, it also display error codes for better understanding of the performance status of the voltage stabilizer unit.
4. State of the art workmanship and product finishing.
