Frequently Asked Questions
Can I use the SDR-240-48 for a 48V industrial control cabinet with higher load demand?
Yes, this model provides 48V output up to 5A, with 240W total capacity, so it fits 48V control cabinet loads that need more power than a 120W supply. It is designed as a DIN rail power supply for industrial panels.
Is the SDR-240-48 suitable for 48V building management or automation systems in an enclosure?
It is appropriate for enclosed 48V building management or automation systems when the total connected load does not exceed 240W or 5A. The 88-264VAC input range supports use across a broad span of standard AC supply conditions.
Can this unit be used where a 48V DIN rail supply is needed but panel space is still a concern?
Yes, it combines 240W capacity with a DIN rail form factor measuring 125.2 x 113.5 x 63.0 mm. That makes it useful for 48V cabinet applications needing more output without moving to the larger 480W class.
Should the SDR-240-48 be mounted in a protected control cabinet?
Yes, this power supply is best used inside an enclosure or control cabinet rather than in an exposed environment. Its rated operating temperature is -25°C to +70°C, and it is certified to BSMI, CB, CE, cUL, EAC, c_gl, and TÜV.
What is the difference between the SDR-240-48 and other SDR models in the same family?
The listed related models are SDR-120-12 at 120W, 12V, 10A; SDR-120-24 at 120W, 24V, 5A; SDR-120-48 at 120W, 48V, 2.5A; SDR-240-24 at 240W, 24V, 10A; SDR-480-24 at 480W, 24V, 20A; SDR-480-48 at 480W, 48V, 10A; SDR-480P-24 at 480W, 24V, 20A; and SDR-480P-48 at 480W, 48V, 10A. The same family list also includes SDR-75-12 at 75.6W, 12V, 6.3A; SDR-75-24 at 76.8W, 24V, 3.2A; SDR-75-48 at 76.8W, 48V, 1.6A; SDR-960-24 at 960W, 24V, 40A; and SDR-960-48 at 960W, 48V, 20A.
