PSUs for DIN-rail mounting

November 2014 Electrical Power & Protection

Mean Well has introduced two new families of DIN-rail mounted power supplies providing 40 and 60 W for industrial and security applications.

With features tailored to modern industrial applications, the DRA-40 and DRA-60 series boast output voltage adjustment, protection functions and current adjustment via 1-10 VDC, PWM signal or resistance. These also make them well suited to LED lighting, where current adjustment can be used to alter LED brightness. They are available in variants with 12 or 24 VDC output with front-panel adjustment, and integrate protection against short circuit, overload and over-voltage.

DRC-40 and DRC-60 standard models employ a TTL signal and relay contact, respectively, to provide the AC OK and battery-low alarm signals (the DRC-40 series also has an optional model with a relay contact). Standard functions include short circuit, overload and over-voltage protection, battery-low cutoff, battery reverse polarity protection by fuse, and front-panel DC voltage adjustment.

All of the above power supplies can be mounted on TS-35/7.5 or TS-35/15 DIN rail, and accept inputs across the full 90 – 264 V a.c. range. They are designed to operate fanless in temperatures from -30°C to +70°C, are certified to UL/CUL/CB/TUV/CE safety regulations and meet the requirements of IEC60950-1 Limited Power Source (LPS).
