1.Product application 

Products for the railway system, power system requirements and carefully designed a new generation of intelligent UPS power supply, to meet the requirements of high quality power supply, and suitable for all sensitive to power supply, need stable, reliable, clean, uninterrupted sine wave AC power supply system.

2.Product feature

·The inverter unit adopts advanced SPWM pulse width modulation technology, and the output is a pure sine wave with stable frequency and voltage, filtered noise and low distortion.
·Advanced control theory and mature and stable inverter mode can quickly respond to changes in the external environment and provide uninterrupted, completely high-quality AC output in real time.
·Mature and reliable power frequency mode, online double conversion topology design.
·Fully isolated inverter technology, outputs noise-free sinusoidal AC voltage, and complete transformer isolation between any two circuits of AC input, DC input, and AC output.
·Unique dynamic current loop control technology ensures reliable operation of the inverter.
·Strong overload capability, able to withstand computer startup at full load
High-power bypass switch, which can be powered by the bypass when overloaded
·The inverter has an LED display on the front panel, making the status clear at a glance.
·Provides RS232 or RS485 standard communication interface, supports real-time data communication function, and uses monitoring software to monitor and manage the working status of the inverter power supply in real time
·Perfect overvoltage, undervoltage, overcurrent, short circuit and anti-reverse protection can protect the module under abnormal conditions
·Featured input anti-reverse and input buffer design

3.Protective function
The WD-U series UPS power supply has complete protection functions. Once a fault listed in the table below occurs, the UPS power supply will enter the bypass state or shut down the output to ensure that the load is not damaged. At the same time, the UPS power supply itself is also protected.
