Frequently Asked Questions
Can I use the RDDW20G-15 to power ±15V analog circuits in industrial control equipment?
Yes. This converter provides dual ±15V constant-voltage output with 20W total power, which fits low-power analog sections such as signal conditioning, amplifier rails, and interface circuitry. Its -40°C to +85°C operating range also suits industrial equipment used across broad ambient conditions.
Is the RDDW20G-15 a good fit for embedded test and measurement electronics that need split rails?
It can be a good fit where the design needs dual ±15V output rather than a single positive rail. The 20W rating and compact 50.8 × 25.4 × 10.2 mm size make it suitable for space-constrained embedded assemblies with moderate power demand.
Can this converter be used inside automation cabinets for sensor interface or analog I/O boards?
Yes, if the board or module is designed around ±15V constant-voltage power. The 20W output is aimed at low-power automation electronics rather than large field loads, and the miniature package helps in dense cabinet layouts.
Would the RDDW20G-15 work in equipment exposed to vibration or elevated internal temperatures?
The listed features state 5G vibration resistance and 70°C operation, and the operating temperature range is -40°C to +85°C. That makes it better suited to industrial or mobile equipment than converters intended only for benign indoor electronics environments.
How does the RDDW20G-15 compare with the other RDDW20G models?
Within the RDDW20G family, all listed models are 20W units. The RDDW20G-05 is 5V at 2A, the RDDW20G-12 is 12V at 835A, and the RDDW20G-15 is 15V with dual output. Selection in this group is mainly based on the required output voltage.
