MEAN WELL | SPWM-240-48DA2 240W 48V Constant Voltage PWM Output LED Driver

The MEAN WELL SPWM-240-48DA2 is a 240W AC/DC LED driver featuring a 48V constant voltage PWM output. It delivers a maximum rated current of 5A and a maximum rated output power of 240W, with an adjustable output voltage range of 47V to 50V. Its PWM output helps maintain consistent colour temperature and even brightness when powering compatible LED strip lighting.

This DA2 model supports DALI 2 DT6 control with a single channel output, alongside primary side PUSH dimming. DALI 2 control provides a minimum dimming level of 0.1%, while the fixed 3.2kHz PWM output supports smooth and flicker free lighting performance. Up to ten drivers can also be operated together using one common push button, with a maximum control cable length of 20 metres.

The driver operates from an input range of 180V to 305VAC and achieves efficiency levels of up to 94%. Standby power consumption remains below 0.5W when dimmed off, while the fanless design uses free air convection cooling for quiet and reliable operation. Its slim Class II plastic housing measures 380 × 38 × 28.5mm.

Built in protection is provided against short circuit, overload, over voltage and over temperature conditions. The SPWM-240-48DA2 is designed for LED strip lighting, decorative lighting, architectural lighting, household lighting control systems and DALI building automation applications. It is supplied with a 5 year manufacturer warranty.
