Feature: 1. The outer shell is made of high‑quality aluminum alloy with high heat dissipation, good heat dissipation, and improving work efficiency while protecting the components. 2. Remove the cumbersomeness to make it lighter. Reduce external volume, focus on internal configuration, stable performance, long service life. 3. Convert the voltage of a single level into the current or voltage required by the user using a different approach structure. 4. The transistor on the power supply consumes less energy and is highly efficient, so the energy saving effect is excellent. 5. Suitable for LED power supply, medical power supply, display power supply, industrial control field, power equipment, instruments and meters, solar photovoltaic power supply.

Package List: 1 x Regulated Switching Power Supply Note: Switch power supply products before use, please read the operation manual carefully, check whether the switch power supply current and voltage and load current and voltage meet the requirements of use. 1. The switching power supply must pay attention to the internal high‑voltage part of the machine, can not touch the internal parts of the machine, non‑professionals do not open the power supply maintenance, otherwise there is the risk of electric shock. Before use, read the relevant wiring marks clearly Please turn off the input power when wiring. 3. In order to ensure the safety of operation and reduce interference, please ensure that the grounding terminal FG is reliably grounded. (The grounding wire diameter should be reasonably selected according to the input voltage and output power) 4. Check whether the mounting screw is in contact with the power board device, and measure the insulation resistance between the shell and the input/output to avoid electric shock. 5. Most of the LED switching power supply housing is the heat dissipation part, increase the contact area between the housing and the case when installation, in order to facilitate heat dissipation and prolong the life of the power supply, if the power supply has a built‑in fan, the fan vent can not be blocked. 6. Before the installation of power, please carefully check whether the wiring is correct, to prevent the wrong connection, reverse connection phenomenon. Do not enable it until you are sure
