4 Switching On/Off Remotely
The PSU turns on automatically by plugging it into the mains. However, it also has a 3-pin port
which can be used to remotely power the PSU on and off.
Remote On/Off Method 1: Use the physical power switch to control ON/OFF and GND lines,

closing the circuit turns the machine on, and breaking the circuit turns the machine off.
Remote On/Off Method 2: 5V sb PSU supports an external MCU, which controls a transistor
or MOSFET to manage the ON/OFF pins to switch the PSU ON/OFF remotely. The PSU will
turn on once power is provided to the 5V sb pin.

6 Trouble Shooting & FAQ
#
Issue
Reason
Troubleshooting
1
Fan won’t run, and no
12V output
AC Input is abnormal
1. Make sure the AC input wire has a good
connection and the plugs are
connected firmly
2. Make sure the mains power is working
well and its voltage is above 205V.
2
The fan is running, but
there is no 12V output.
1. Voltage in your
power system is
lower than required
2. PSU is in protection
mode
1. Please check whether the voltage is
above 205V with multimeter to make
sure the PSU can switch on correctly.
2. Check whether there is a short circuit
output or overload that is causing the
PSU to enter a locked status. After
removing the problem, the PSU should
power up.
3
After a few minutes,
the PSU stops working,
starts working, stops
working and keeps
cycling.
PSU is in over-heat
protection
1． Check whether the fan is working
2． Check whether the fan’s vent is being
blocked
3． Check whether there is a dust buildup
inside the PSU due to prolonged use.
Do NOT remove the PSU’s cover unless
trained to do so.
4． Check the power and ambient
temperatures follows the
Load/Temperature graph
4
Output is normal, but
the fan is not working.
Fan is broken
1. Check that the fan is clear of blockages
or buildup
2. Fan is broken and needs to be replaced.
5
The PSU suddenly has
no output and can’t be
started again.
The PSU is in
over-current protection.
Check whether the load current has
exceeded the built-in overcurrent
protection limit. The protection
automatically triggers when the load
current exceeds the limit to protect against
damage to the PSU and the server.

7 Precautions for Use
1. Before using the PSU, please ensure that the voltage and power outputs are compatible
with your equipment.
2. Please ensure that the PSU appears to be in good shape and has not suffered damage in
transit. If the exterior of the PSU appears damaged, do not use it.
3. Make sure that the metal cover for the PSU with on/off switch is properly grounded.
Improper grounding is dangerous.
4. The PSU must be installed in such a way that it receives good, unobstructed airflow.
Under no circumstances should the PSU be installed in an enclosed place.
5. When installing the PSU, please double check that the output polarities are the correct
way round, and that the screws are fastened securely in place.
6. Do not attempt maintenance on any wiring while the PSU is powered up from the mains.
7. Running the PSU at <80% load or below can greatly prolong the life of the PSU. Usually,
for every 10ºC above the rated amount, the life of the PSU is cut in half.
