MeanWell LED driver power supply

The PWM-90-DA power supplies have been specifically designed for applications in intelligent dimming and feature a pulse-width modulated constant voltage output (PWM) with a frequency of 1.47 kHz. The switch-mode power supplies comply with the international DALI standards IEC62386-101, 102, and 207, ensuring user safety. In standby mode, the power consumption of the DALI variant is below 0.5 W. Thanks to the fully encapsulated IP67 plastic housing, the LED drivers of protection class II are particularly robust and waterproof. Suitable applications include commercial LED lighting, office lighting, and decorative LED lighting for both indoor and outdoor use. The PWM-90-DA has built-in active power factor correction (PFC), and the operating temperature range is between -40 and +85 °C.
