Tired of power supplies that cant handle the voltage swings in a busy factory? The MEAN WELL WDR Switched Mode DIN Rail Power Supply is built to keep your machines running smooth even when the input power is unstable. It gives you reliable 24 V DC power for automation, cameras, and telecom gear, so you never lose production time.
MEAN WELL WDR Switched Mode DIN Rail Power Supply
Many industrial sites face wide AC input ranges from 180 V to 550 V. When a supply cannot accept that range, it shuts down or overheats, causing costly downtime. This problem matters because every minute of lost operation hurts the bottom line. The WDR series accepts the ultra-wide range, stays cool in temperatures from -30 C to +85 C, and delivers up to 2.5 A at a stable 24 V output. The result is a simple, safe, and efficient power source that fits on a standard DIN rail.
Key Features
- Accepts 180 V-550 V AC or 254 V-780 V DC input.
- Adjustable output voltage from 24 V to 29 V (+20 % max).
