FAQ
Can I use the DLW05B-05 in a 24V-class industrial cabinet to generate 5V for control electronics?
Yes, if the source presented to the converter is within 18-36VDC and the electronics need a regulated ±5V output. With a 5W rating, it fits low-power control, monitoring, and interface electronics rather than heavier 5V loads.
Is the DLW05B-05 suitable for small embedded systems in automation equipment with higher DC input ranges?
It is a fit for embedded systems that need a regulated ±5V output when the available input falls in the 18-36VDC range. The small 50.8 × 25.4 × 11.27 mm footprint helps when space is limited inside automation equipment.
Can this model be used for industrial monitoring nodes or interface boards that run on 5V?
Yes, when the monitoring node or interface board needs a regulated ±5V output and stays within the 5W output rating. The 18-36VDC input range makes it more appropriate where the upstream DC source is higher than the A-series 9-18VDC input range.
Can the DLW05B-05 be used in outdoor control boxes?
Its stated operating range is -25°C to +71°C (with load derating per the derating curve), but the provided specifications do not give an IP rating. Without an IP rating, it is safer to treat it as suitable for protected indoor equipment or an enclosure that handles moisture and dust protection.
What changes across the DLW05B output options?
The DLW05B family keeps the same 5W power level, 18-36VDC input range, regulated dual output, 50.8 × 25.4 × 11.27 mm size, 31.2 g weight, and -25°C to +71°C operating temperature. The output choices are DLW05B-05 at ±5V and up to ±500mA, DLW05B-12 at ±12V and up to ±208mA, and DLW05B-15 at ±15V and up to ±167mA.
