Feature: 1. Highquality aluminum alloy material is corrosionresistant, wearresistant and durable with good heat dissipation. 2. The heat dissipation hole design of perforated mesh is combined with aluminum alloy to resist high temperature. 3. Optimized components to ensure stable performance and long service life. 4. Adopting EMI filter circuit, switching power supply is antiinterference and its output is more stable. 5. It is suitable for access control display system, monitoring equipment, light box advertising, LED equipment, etc. Specification: Item Type: Switching Power Supply Material: Aluminum Alloy Product Model: YY-15-12 Input Voltage: AC 100-264V Output Voltage: DC 12V Output Current: 1.25A Error Range: 1% Adjustable Pressure Range: 5% Power: 15W Maximum Waterproof Rating: IP20 Start, Rise, Hold Time: 200ms, 50ms, 20ms Working Temperature and Humidity: -10-60, 20%-90%RH Storage Temperature and Humidity: -20-80, 10%-95%RH Product Size: Approx. 70x40x33mm / 2.8x1.6x1.3in Purpose: Industrial automation, PLC control cabinet, DC motor, medical equipment, access control display system, monitoring equipment, light box advertising, LED equipment. Package List: 1 x Switching Power Supply Note: Before using the switching power supply product, please read the manual carefully to check whether the current and voltage of the switching power supply and the load current and voltage meet the requirements of use.1. When using the switching power supply, be sure to pay attention to the internal highvoltage parts of the machine, and do not touch the internal components of the machine. Nonprofessionals should not disassemble the power supply for maintenance, otherwise there is a danger of electric shock. Before use, read the relevant wiring marks.2. When wiring, turn off the input power.3. To ensure safe use and reduce interference, please ensure that the ground terminal FG is reliably grounded. (The grounding wire diameter is reasonably selected according to the input voltage and output power).4. Check whether the mounting screws are in contact with the power supply board components, and measure the insulation resistance between the housing and the input/output to avoid electric shock.5. Most of the LED switching power supply case is the heat dissipation part. When installing, increase the contact area between the housing and the case to facilitate heat dissipation and prolong the life of the power supply. If the power supply has a builtin fan, the vent of the fan cannot be blocked.6. Before the installation is complete, please carefully check whether the wiring is correct, and prevent the wrong connection or reverse connection. Enable it after confirming that it is correct.
