Production Information
 

PBD Uninterruptable Power Supply


The system runs in online mode normally. The AC input goes through the input isolating transformer, rectifier, filter and inverter, hence be sent through output isolating transformer and filtered again, thus a perfect sine AC output is produced. In the case of AC supply fault( over /under voltage or fail, rectifier fault ,etc), the system will shift to DC input and through inverter, output isolating transformer and EMI filter to get a perfect AC output with no transient supply interruption. If there happens that both AC and DC input fails, the system will shift to electronic bypass circuit by micro-processor(CPU) to continue power supply with the time less than 4ms. The system is furnished with repairing bypass circuit as well to ensure no interruptible power supply when system fault or repair met with the shift time 0ms. Moreover, the repairing bypass can also prevent mis-operation and avoid electrical power cut caused by operation.
