Safety terms:
1. The Y capacitor inside power supply could deliver leakage current. When multiple
power supplies work in parallel or in series, the leakage current will increase to cause
the possibility of getting electric shock. Make sure ground wire is thick enough to
prevent the danger.
2. For AC input switching power supplies, the voltage running through primary circuit could
up to 2~4 times of AC input voltage. It is forbidden for non-technicians to open the
case. Contact your local dealer for technical support if needed.
3. The temperature inside power supply may exceed
85
℃
(185
℉
) during full loading, so it
is dangerous to touch power supply at this time. Be sure to keep a proper distance
between power supply and combustible material.
Trouble Shooting:
If power supply couldn't work properly, please turn off input power SW, and check the
following steps:
1. Check all the connections (pin in/out correct? polarity correct? etc.)
2. Does terminal well connected? If not, reconnect it, and then turn on input power source
again.
3. Check load current. If over loaded, decrease loading, and then turn on input power
source again. (Rated load current show on label)
4. If there comes a sudden output interruption during adjusting VR, please turn VR to the
middle value, and then turn on AC power again.
5. If there is a temporary working followed by power supply shut down, it may cause by a
higher inrush current requirement of the system. Replace a higher output power supply
to meet the system’s requirement.
6. If environmental temperature gets too low or too high?
(1) If the environmental temperature lower than
-20
℃
(-4
℉
)
, take either of the
following steps:
a. Use heater to warm up the environment; or, b. Reduce loading.
(2) If environmental temperature higher than
50
℃
(122
℉
)
, use extra cooling fans to
enforce air convection, or reduce loading. (Refer to related specification)
7. If the fuse inside power supply melted, there must be something function abnormally.
Find out the abnormal cause and remove it; and then replace a new fuse. Make sure
the new fuse’s spec must be same as the original.
If all of the above items were checked and power supply still cannot
function normally, please contact your local dealer for support or
e-mail us:
