Waterproof types:
AC Input: yellow/green lead is for grounding, rest leads are for electricity
DC Ouput: Red (brown) pos, black (blue) negative -
Non-waterproof types:
1) The power supply will be automatically protected and enter the abnormal state of
2)
For models have multi-outlets, never connect all loading with single outlet,
please keep balanced loading. If connecting with only single outlet is
necessary, please connect all positive output leads together to provide
electricity fully, also negative leads.
3) Please be well noticed that too long connecting leads will cause to line loss. So please
4) Input/output lead’s surface listed its diameter and industrial standard, please choose
proper extension leads accordingly. In view of the line loss, the longer extension, the
stronger leads is needed.
5) This power supply can be connected with plugs, but please make it well connected
and insulated.

LED POWER SUPPLY Trouble-shooting Tips
There is a protection circuit in the Power Supply that will cut off (trip) the power whenever an short circuit or overload condition
occurs, please make sure correct connection of positive and negative ter, -) before power on.
1. Power Supply does not work:
1) Check the input power voltage.
2) Check power on/off status.
3) Check if there’s short-circuit on output line.
4) Check if wrong positive and negative terminal connection.
5) Check if the output indication light is lighting (for the models which have this function).
6) Check if the fuse well connected (for the non-sealed models ).
2. Over-heated of the Power Supply:
1) Keep good ventilation.
2) Check the loading status, avoid over loading.
3. Unsteady power output:
1) Check if there's over-loading or improper output extension leads connected.
2) Check if there's strong interference in the working environment.
3) Check if there's magnetic field around the working environment.
4. LED light works dark (weak light, LED not bright enough)
1) Please check if the output voltage is good for your requiremnt(5V/12V/24V...etc.).
2) Choose proper wires in aspects of wire's diameter and voltage capacity.
3) Check if there's over-load or too long extension leads been used.
IV. Wire Connection
Make sure wires are well connected, most of our models have multi-outlets, we recommmend the following loading order: negative –
positive- negative- positive- negative….etc. Please always keep balanced loading.
Cautions for Connecting Leads and Loading
intermittent connection if the load power exceeds the maximal rated output power
(normally 5~20% exceeds).
avoid too long extension with ouput leads.
The installation and wire connection of this power supply should be conducted by qualified
technicians!
