Information about the MEAN WELL PWM-60-48

The MEAN WELL PWM‑60‑48 is a 60 W constant‑voltage LED driver with a 48 V DC output and PWM‑style regulation, making it particularly well suited for long 48 V LED strip runs and multi‑segment constant‑voltage LED systems. The PWM output keeps the LED current waveform stable, so brightness and colour remain uniform over the full dimming range, even at very low light levels.

One of its main strengths is the combination of up to 90 % typical efficiency, active power factor correction and a wide 90–305 V AC input range, which together provide efficient operation and global compatibility in a single model. The fully potted IP67 housing, wide case temperature range from −40 °C to +85 °C and robust protection set (short‑circuit, overload, overvoltage, overtemperature) allow the PWM‑60‑48 to operate reliably in dry, damp and wet environments, including demanding industrial and outdoor installations.

A key unique characteristic of the PWM‑60 series, and the 48 V version in particular, is the flexible dimming interface: the 3‑in‑1 input supports 0–10 V, 10 V PWM and resistive control, while DA and DA2 variants add DALI and DALI‑2 for integration into professional lighting control and building management systems. Combined with its long MTBF, comprehensive safety and EMC approvals and constant‑voltage PWM behaviour optimised for strip lighting, the PWM‑60‑48 is an excellent choice for façade lighting, architectural accents and any 48 V LED project that requires precise dimming and high reliability.
