Frequently Asked Questions
Can I use the SDR-120-48 for a 48V PLC cabinet or industrial control panel?
It can be used where the control system requires 48V DC and the total load stays within 120W or 2.5A. The DIN rail format and 125.2 x 113.5 x 40.0 mm body also support compact control panel layouts.
Is the SDR-120-48 appropriate for 48V building automation equipment in an enclosure?
Yes, this model is designed for 48V DC output and fits enclosed building automation or control cabinet applications that need up to 2.5A. Its 88-264VAC input range allows use with a broad range of standard AC supply conditions.
Can this 48V DIN rail supply power industrial automation devices that need a slim panel power source?
Yes, if the equipment requires 48V DC and the combined draw does not exceed 120W. The 40.0 mm slim profile helps when DIN rail space is limited in smaller automation cabinets.
Is the SDR-120-48 suitable for open-air locations, or should it stay inside a cabinet?
This unit is better matched to protected indoor control cabinets or enclosures than exposed mounting conditions. Its specified operating range is -25°C to +70°C, and it carries BSMI, CB, CE, cUL, EAC, c_gl, and TÜV certifications.
