Module short circuit module will be turned off when no current output, after the failure to remove will not automatically return to work, need to restart the module will only work when the power is cut off. The output over voltage protection:

Hardware protection point between 410.5 V (+ / - 3.5 V), hardware overvoltage protection after need human intervention to boot.

Overvoltage protection point can be set by monitoring module software, software overvoltage protection setting range is 240 V ~ 460 V, and higher than the output voltage of 3.5 V above;

Can choose by monitoring module software protected mode:

1) overvoltage lock mode at a time

When the module software overvoltage occurs, module shutdown and maintain, need human intervention may be resumed only;

2) four overvoltage lock mode (factory default)

Module software protection, the module power off within 5 seconds to boot, if in a set time (defaults to 5 minutes, can be set by monitoring module) fourth overvoltage, module is turned off and keep, requires human intervention to boot. If module output current is less than 10% of the rated output current, the module is not turned off.

Manual intervention methods: through monitoring module reset module, also can be pulled away from the system module to copy.

Product surface is bright and clean, there should be no obvious dent, scratch, crack, deformation, surface coating layer should not be bubbles, cracks and peeling, metal parts should not have burr, rust, and other mechanical damage. Switch should be convenient, flexible and reliable operation, no loose parts firm. Input and output terminal without ablation. To explain the text symbols of function and function should be clear and correct.
