Confirm whether the power supply of rated input voltage before installation in the city within the scope of voltage

Confirm whether the power supply of rated input voltage before installation in city voltage range, such as the power of the input voltage is AC100 ~ 265 v, the power grid voltage cannot exceed 265 v and less than 100 v, because when the power grid will be damaged more than 265 v power supply for a long time, when the grid voltage is less than 100 v, the power supply may appear to not work properly.

2, pay attention to the power of the distinction between the input and output line, avoid the line power supply caused by damage or unnecessary accidents.

3, in order to guarantee the safety of using and reduce interference, please ensure that the ground wire (FG) and reliable grounding.

4, don't use under overload, light load, power supply output power and power matching lamps and lanterns as far as possible. Should make when matching with the power output of 80%.

5, such as power supply is isolated, when using, make sure pick up good load first, then connect the input power, otherwise it will burn the LED lamp bead.

6, in order to prolong the service life of power supply, power supply installation work in good for heat dissipation of the environment as far as possible:

A, it is forbidden to install the power supply work in high temperature environment.

B, bare in ventilation air as far as possible;

C, such as the installation in a closed environment, the power must be contact with the metal case of lamps and lanterns effective, but can't blow up direct contact in case of short circuit or other effective cooling way, make the heat generated by the power supply can effectively spread to the surrounding air.

7, environment and the role of power relations

In pieces with environmental temperature.

Mixer power using power decreases.

The life of the mixer power also gradually reduced.
