Lcd Display Automatic Voltage Controller with Battery

Lcd Display Automatic Voltage Controller 

Voltage fluctuations can lead to unplanned production line shutdowns, causing the  production line to operate abnormally and product quality to decline. It can also lead to  serious consequences caused by production line disorder and disorderly start-up. In  addition, the wear and tear on the machine is increased, which in turn shortens the  service life and even damages the equipment. The Automatic Voltage Controller (AVC)  developed by our company is an inverter-based system used to protect sensitive  industrial and commercial loads from voltage fluctuations. This product can quickly and  accurately compensate for voltage sags and swells, and can provide continuous voltage  regulation and load voltage compensation functions. At the same time, the product has  a power-off protection function, and the internal clock and user-set parameters are not  affected by system power outages. The automatic voltage regulator is a three-phase  five-wire single-phase compensation transformer-type voltage regulating output, which  is suitable for situations where the voltage is unbalanced.

The automatic voltage regulator is composed of AC-DC-AC converter, knife switch QS, circuit breaker QF, contactor KM and compensation transformer. The AC-DC-AC converter uses fully controlled power electronics to realize bidirectional energy flow. Knife switch QS is cut to bypass state during maintenance. The contactor KM is used to turn off or on the load in the compensated state. By sampling the grid voltage, the automatic voltage regulator monitors whether the grid voltage deviates from the set value in real time. Once it deviates from the set value, it controls the AC-DC-AC converter to output a voltage with the same or opposite polarity of the grid voltage, and adjusts the voltage amplitude and polarity of the compensating transformer in series in the main loop to ensure the stability of the load terminal voltage.

Available in sizes from 30 to 500 kVA, the outdoor automatic voltage regulator provides superior voltage regulation.  Capable of withstanding climactic extremes from -20° to +50°C, the AVC is uniquely suited to provide regulated precision power to mission critical outdoor loads.  Each phase is independently regulated, and the PCBs are fully connectorized for ease of service.  Applications include oil & gas, mining, construction, chemicals, water treatment, and defense.
