4 N+1 REDUNDANT OPERATION
Confirm the following items before you think the module is
damaged or failed.
1)No Output
2)High Output Voltage
● Is the rated input voltage supplied?
● Are the ON/OFF control terminal, remote sensing
● For adjusted output, is the variable resistor network
● Is there any troubles with the connected load?
● Is the remote sensing connected correctly?
● For adjusted output, is the variable resistor network
