Mean Well power supplies are designed to high standards of efficiency, lifespan, and reliability. They allow for full load burn-in and switch between 120 VAC and 208-240 VAC input to work with various common input voltages. 36 VDC output can be adjusted up to 39.6 VDC to make up for voltage drop. Built-in protections for short circuit, overload, over voltage, and over temperature guard against and prevent premature failure.
