Installation note: This is a high-voltage constant-current LED driver, not a conventional fixed-voltage power supply. Verify the LED module's required voltage, current, power, and DALI-2 compatibility before installation. The standard DA2 version does not include the optional 12V/250mA auxiliary output available on the DA2-A version. Electrical installation should be performed by a qualified professional.
