Frequently Asked Questions

Can I use the PWM-120-48 to power 48V LED strips outdoors?

Yes. The IP67 waterproof rating allows the PWM-120-48 to be installed in outdoor or exposed locations, and its operating temperature range of -40°C to +90°C accommodates most climate conditions. The Class II isolated design also reduces safety concerns in wet environments.

How many meters of 48V LED strip can the PWM-120-48 drive?

The PWM-120-48 delivers up to 120W at 48V. Divide 120W by your strip's watt-per-meter rating to find the maximum length — for example, a 20 W/m strip allows up to 6 m. Always verify the strip's rated power consumption per meter before sizing.

Is the PWM-120-48 suitable for 48V LED signage with dimming capability?

Yes. The built-in 3-in-1 dimming supports PWM signal, 0–10V, and resistance control, making the PWM-120-48 compatible with most external dimmer controllers used in illuminated signage. Its 120W capacity supports medium-format 48V sign cabinets.

Can the PWM-120-48 be used for long-run linear architectural lighting at 48V?

Yes. 48V systems allow longer cable runs with lower voltage drop compared to 12V or 24V, and the PWM-120-48 provides up to 120W to take advantage of that. It is a good match for linear architectural lighting fixtures or LED channels using 48V strip.

Is the PWM-120-48 appropriate for outdoor landscape uplighting at 48V?

Yes. The IP67 rating and -40°C cold-start performance make the PWM-120-48 reliable in ground-level or buried-enclosure landscape installations. At 2.5A output current it can supply multiple 48V uplights up to a combined 120W load.

How does the PWM-120-48 compare to other PWM-series drivers at 48V?

The PWM series at 48V includes: PWM-40-48 (40W, 0.84A), PWM-60-48 (60W, 1.25A), PWM-90-48 (90W, 1.88A), PWM-120-48 (120W, 2.5A), and PWM-200-48 (200W, 4.17A). DALI versions (PWM-120-48DA, PWM-200-48DA2) are available if DALI control is needed.
