Product Features

◆ Microprocessor logic control, DDS sine wave generation, bipolar full-bridge SPWM inversion; pure output waveform;

◆ Wide AC input range, input voltage fluctuation range ±30%. Input and output are completely isolated;

◆ An LC surge voltage filter is added to the input end to filter out surge voltages below 600V from the power grid.

◆ The two outputs are isolated from each other, and the inversion control is isolated, so no isolation transformer needs to be added to the output end.

◆ Active soft switching power factor correction is used to achieve an input power factor of 0.99.

◆ LCD and LED dual display, clearly understand the various conditions and parameters of the power supply;

◆ The unit has a self-test function for faults, which can automatically detect, process, and alarm faults.

◆ When switching between two inputs, the module can provide a 150ms hold-up time.

◆ Dual-machine hot backup switching time is less than 25 milliseconds.

◆ Modules can be used in parallel with hot backup, and automatic switching is completed within 25 milliseconds after a fault.

◆ Meets electromagnetic compatibility TB/T3073-2003, CLASS A requirements.

◆ The power supply screen design conforms to the railway standards TB/T1528.1-2002 "Railway signal power supply screen Part 1 General principles" and TB/T1528.7-2002 "Railway signal power supply screen Part 7: 25Hz signal power supply screen"
