Frequently Asked Questions
Can I use the PWM-120-12DA with a DALI building management system to control 12V LED strips?
Yes. The PWM-120-12DA has a DALI dimming interface, allowing it to be addressed and controlled by any DALI-compliant building management or lighting control system. It outputs 12V at up to 10A (120W) with a PWM-style waveform suited for 12V LED strips.
Is the PWM-120-12DA suitable for outdoor architectural LED lighting installations?
Yes. The IP67 rating means the driver is fully protected against dust and temporary water immersion, making it appropriate for outdoor architectural or landscape lighting enclosures. Its -40°C to +90°C operating range covers a wide range of climate conditions.
How many meters of 12V LED strip can the PWM-120-12DA power?
With a maximum output of 120W at 12V, the usable strip length depends on your strip's wattage per meter. For a 12W/m strip, that is up to 10 meters (120 ÷ 12); for a 14.4W/m strip, approximately 8.3 meters (120 ÷ 14.4). Check your strip's rated power per meter and apply a 20% safety margin.
Can the PWM-120-12DA be used to power 12V LED signage in a DALI-controlled office environment?
Yes. The DALI interface allows the driver to integrate directly into DALI lighting networks common in commercial office environments. The 120W, 12V output is appropriate for powering 12V LED modules or strips inside illuminated signage.
Does the PWM-120-12DA work in very cold outdoor installations, such as freezer rooms or northern climates?
Yes. The operating temperature range of -40°C to +90°C means the PWM-120-12DA is rated for operation in freezer room temperatures and cold outdoor climates without performance derating.
Can I use the PWM-120-12DA in a museum or gallery display case needing precise DALI dimming of 12V LED strips?
Yes. The DALI interface provides precise digital dimming control, which is well-suited to museum and gallery environments where consistent, programmable lighting levels are required. The PWM-style output delivers smooth dimming to 12V LED strips at up to 10A.
