Information on MEAN WELL PSD-15B-12
The MEAN WELL PSD-15B-12 is a compact and highly reliable 15 W open-frame DC/DC switching power supply designed for internal equipment integration. It accepts an input voltage range of 18 to 36 V DC (nominal 24 V DC) and provides a single regulated 12 V DC output delivering up to 1.25 A of current. Measuring just 94 x 49 x 25 mm, it provides space-efficient power distribution for embedded electronics, industrial controllers, and telecommunication devices.
Operating with a typical efficiency of 78%, the unit utilizes fanless free air convection for cooling across a working temperature range of -10 °C to +60 °C. For quick assembly, it features industry-standard JST pin connectors (JST B3P-VH for input, JST B2P-VH for output). Built-in protection includes short circuit, overload (hiccup mode with automatic recovery), overvoltage (Zener diode clamping), and input polarity protections. Certified to BS EN/EN 55032 Class B EMC requirements and compliant with EAC standards, the PSD-15B-12 comes backed by a 2-year manufacturer warranty.
