NES-35-12 Mean Well 12VDC 3A 36W Switching Power Supply

Description

Mean Well NES-35-12 99 x 97 x 36 mm 12 VDC 3 A enclosed AC/DC switching power supply is a chassis-mounted component designed for regulated voltage conversion. It features a universal AC input range of 85 to 264 VAC and a DC input range of 120 to 370 VDC. The unit is constructed with a metallic chassis for free air convection cooling and utilizes a screw terminal block interface for input and output connections. Integrated protections include hiccup mode for short circuit and overload conditions, alongside a shut-down mechanism for over voltage. The internal circuitry supports a 36 W power rating with a typical efficiency of 81 % and a ripple and noise peak of 120 mVp-p.
