Frequently Asked Questions
Can I use the RDDW20F-12 for ±12V analog or instrumentation circuits in a 24V control system?
Yes, this converter is designed for constant-voltage conversion from a 9-36VAC input to a ±12V output. That makes it suitable for industrial or embedded electronics that need dual 12V rails and stay within the 20W power rating.
Is the RDDW20F-12 a fit for automation interface boards that need isolated-looking dual 12V rails in a small space?
It is sized for compact assemblies at 50.8 × 25.4 × 10.2 mm and provides a dual ±12V output in a 20W format. For compact automation or embedded boards, the small footprint is often useful where panel or PCB space is limited.
Can this model be used in machine electronics exposed to vibration and elevated heat?
The listed features include 5G vibration resistance and 70°C operation, which points to use in more demanding industrial environments than basic indoor electronics. The full operating temperature spec is -40°C to +85°C, provided the application matches the ±12V constant-voltage output.
Is the RDDW20F-12 appropriate for outdoor use or only inside protected equipment?
Its temperature range of -40°C to +85°C supports cold and hot operating conditions. However, no IP rating is provided, so the specs do not support claiming exposed outdoor use; it is better suited to protected housings or cabinets.
What is the difference between RDDW20F-12 and the other RDDW20F variants?
The RDDW20F family keeps the same 20W rating, 9-36VAC input, constant-voltage design, 50.8 × 25.4 × 10.2 mm size, 0.035 kg weight, and -40°C to +85°C operating range across the series. The outputs differ by model: RDDW20F-05 is ±5V at 2A, RDDW20F-12 is ±12V at 835A, and RDDW20F-15 is ±15V at 666A.
