FAQ
Can I use the DLW05C-12 in a 48V automation system that needs a 12V rail?
This model accepts 36-72VDC input and provides a regulated ±12V dual output at 5W. That makes it suitable for low-power automation electronics or interface modules that need ±12V derived from a higher-voltage source in that input range.
Is the DLW05C-12 suitable for embedded 12V analog or control circuits?
It can be used where the design needs a regulated ±12V output and the upstream supply is within 36-72VDC. Because the rated power is 5W, it is better suited to compact control, sensing, or signal-processing sections than to larger 12V loads.
Would the DLW05C-12 fit a compact industrial electronics design?
Its dimensions are 50.8 × 25.4 × 11.27 mm and its weight is 31.2 g, so it is built for compact integration. That physical format can work well in small embedded or industrial assemblies where a ±12V rail is needed from a 36-72VDC input source.
Can this converter be used in uncontrolled indoor environments?
The operating temperature range is -25°C to +71°C (with load derating per the derating curve) and humidity 20% to 90% RH non-condensing, which supports a wide range of indoor equipment conditions. The specs do not list an IP rating, so the product data does not support claiming outdoor, sealed, or washdown use.
How does the DLW05C-12 differ from the other DLW05C outputs?
The series keeps the same 5W platform and 36-72VDC input while changing output options. The DLW05C-05 is ±5V with up to ±500mA, the DLW05C-12 is ±12V with up to ±208mA, and the DLW05C-15 is ±15V with up to ±167mA.
