Frequently Asked Questions

Can I use the PWM-120-36 to drive 36V LED strips outdoors?

Yes. The PWM-120-36 carries an IP67 waterproof rating, meaning it is protected against temporary submersion and can be mounted in exposed outdoor locations. Its operating temperature range of -40°C to +90°C also covers most outdoor climates.

How many meters of 36V LED strip can the PWM-120-36 power?

The PWM-120-36 supplies up to 120W at 36V. Divide 120W by your strip's rated wattage per meter to get the maximum run length — for example, a 14.4 W/m strip allows up to about 8.3 m. Always check your strip's rated power per meter before sizing.

Is the PWM-120-36 suitable for dimmable 36V LED signage applications?

Yes. The PWM-120-36 features built-in 3-in-1 dimming, accepting PWM, 0–10V, and resistance control signals. At 120W and 36V it is well-matched to medium-format illuminated signage that uses 36V LED modules or strips.

Can I use the PWM-120-36 for architectural lighting channels that require smooth dimming?

Yes. The PWM-style output of this driver produces smooth, flicker-reduced dimming suitable for architectural lighting channels and cove lighting using 36V LED strips. The 3-in-1 interface lets you connect it to standard dimming controllers.

Is the PWM-120-36 a good fit for landscape lighting fixtures rated at 36V?

Yes. The IP67 rating protects the unit against rain and moisture, and the -40°C cold-start capability makes it reliable in outdoor landscape installations. At 3.4A output current it can support multiple 36V landscape fixtures up to a combined 120W.

What dimming interfaces does the PWM-120-36 support?

The PWM-120-36 supports three dimming methods via its built-in 3-in-1 dimming circuit: PWM signal, 0–10V analog control, and resistance (potentiometer) control. You do not need an external dimming module to use these interfaces.

How does the PWM-120-36 compare to other wattage options in the PWM series at 36V?

The PWM series offers three 36V options at different power levels: PWM-40-36 (40W, 1.12A), PWM-60-36 (60W, 1.67A), PWM-90-36 (90W, 2.5A), and PWM-120-36 (120W, 3.4A). A 200W 36V option also exists (PWM-200-36, 5.55A) for larger installations. Choose based on your total load wattage.
