Feature: The product is made of high temperature resistant copper enameled wire and adopts double winding U-shaped iron core, which has strong anti-interference ability and high stability. This product uses high quality 16-pin IC. High intelligent protection with short circuit protection, overload protection and overvoltage protection. Ferrite magnetic ring, smaller ripple, low operating temperature. The aluminum material is anti-corrosion and rust-proof, wear-resistant and durable, and the heat-dissipating mesh hole and the aluminum-shaped bottom box combine to dissipate heat better. Switching power supply is widely used in LED, lighting, security monitoring, 3D printing, automation equipment, industrial control, petrochemical, network communication and other fields. Specification: Output current: 2A; 5A Protection function: Overload protection, Overvoltage protection, Short circuit protection Security Certification: CE, ROHS, FCC Working Humidity and Temperature: -15 degrees Celsius - +70 degrees Celsius;20% - 90% RH Product dimension: 110*79*31mm / 4.3*3.1*1.2in Package list: 1 * Switching Power Supply Note: The power supply is 100% full, but some power is lost when wiring. Therefore, it is recommended to use 80-85% of the power. It is strictly forbidden to use in high temperature environment, the power supply should have good heat dissipation space and environment. Do not install the power supply on flammable materials, keep away from gas stations or places where smoking is prohibited..
