The newly designed circuit has a new built-in PWM control IC which brings the max. output wattage up to 52 watts, under natural cooling environments, from 3.3V, 5V, 7.5V, 12V, 15V, 24V, 30V and 48V outputs. With 105°C capacitor built-in, the power unit works with wide range operating temperature from -20°C to +70°C and the new mechanical design hexagonal cover makes for low air flow resistance and better cooling.
