Frequently Asked Questions

Can I use the PWM-120-24 to power 24V LED strip lighting in an outdoor illuminated sign?

Yes. The PWM-120-24 is IP67 rated, making it suitable for outdoor sign cabinets exposed to rain and humidity. It delivers 24V at up to 5A (120W) and operates across a wide input range of 90-305VAC, supporting global voltage standards.

What dimming interfaces does the PWM-120-24 support?

The PWM-120-24 includes built-in 3-in-1 dimming, accepting PWM signal, 0-10V analog, and resistance dimming inputs. This allows compatibility with the most common 24V dimmer controllers without requiring an additional interface adapter.

How many meters of 24V LED strip can the PWM-120-24 power?

The driver provides up to 120W at 24V. For a 20W/m strip, that supports up to 6 meters (120 ÷ 20); for a 14.4W/m strip, approximately 8.3 meters (120 ÷ 14.4). Always check your strip's rated power per meter and leave a 20% safety margin.

Is the PWM-120-24 suitable for use in refrigerated display cases or cold outdoor environments?

Yes. The operating temperature range of -40°C to +90°C means the PWM-120-24 can operate in refrigerated display cases and cold outdoor climates without derating its 120W output.

Can the PWM-120-24 power 24V LED strips in a covered outdoor pergola or building facade?

Yes. Its IP67 rating provides protection against water jets and temporary immersion, making it suitable for covered outdoor installations such as pergola lighting or building facade accent lighting. The Class II design also allows use without a protective earth connection.

How does the PWM-120-24 compare to the PWM-120-12 for LED strip applications?

Both are 120W IP67 drivers with built-in 3-in-1 dimming. The PWM-120-24 outputs 24V at 5A, suited to 24V LED strips which typically allow longer runs before voltage drop becomes significant. The PWM-120-12 outputs 12V at 10A, suited to 12V strips; for equal wattage loads, 24V strips can run roughly twice the length of 12V strips at the same current.

Can I use the PWM-120-24 for cove lighting in a commercial space with 0-10V dimmer controls?

Yes. The built-in 3-in-1 dimming interface accepts 0-10V signals, making the PWM-120-24 directly compatible with 0-10V dimmer controls commonly found in commercial lighting panels. It can drive 24V LED strips used in cove and indirect lighting installations.
