With up to date high frequency switching topology, APV/APC-25/35 series feature with 90~264VAC input range and possess up to 84% of high efficiency, so that they can work between -30~+70℃by only free air convection. APV/C-25 (25W) are not potted while APV/C-35 (35W) are semi-potted for PCB protection and provide the basic ability of anti-moisture, anti-dust as well as heat-conduction purpose. Built-in standard functions include short circuit, overload, over voltage protections, withstand 300VAC surge input for 5 seconds…etc. With IP30 design, these new power units are recommended to apply to indoor LED lighting without the need of high level waterproof and dustproof ability. Typical applications include LED indoor lighting, LED-based decorative lighting, and LED electrical display…etc.
