Frequently Asked Questions
Can I use the RDDW20F-05 to generate ±5V rails for embedded control boards in a 12V or 24V system?
Yes, this model is intended for constant-voltage conversion from a 9-36VAC input to a ±5V output. Its 20W rating and 2A output make it a fit for compact embedded or industrial control electronics that need regulated ±5V rails within that power limit.
Is the RDDW20F-05 suitable for industrial sensor and interface circuits that need dual 5V output?
It can be a good fit where the equipment requires a dual ±5V constant-voltage supply and the total load stays within 20W. The miniature 50.8 × 25.4 × 10.2 mm package also makes it easier to place in dense embedded or automation assemblies.
Can this DC-DC converter be used in vibration-prone mobile or machine-mounted electronics?
This series lists 5G vibration resistance as a feature, which makes it more appropriate for equipment exposed to movement than a basic enclosed board-level supply. It is still a 20W dual-output converter, so the application needs to match the ±5V output and 2A rating.
Is the RDDW20F-05 suitable for outdoor or harsh-temperature installations?
The specified operating temperature range is -40°C to +85°C, so it supports very wide temperature conditions. No IP rating is listed in the provided specs, so it is better treated as a converter for protected enclosures rather than exposed outdoor mounting.
How does the RDDW20F-05 compare with the other RDDW20F models?
All three RDDW20F models share 20W power, 9-36VAC input, constant-voltage operation, 50.8 × 25.4 × 10.2 mm dimensions, 0.035 kg weight, and a -40°C to +85°C operating range. The difference is output: RDDW20F-05 is ±5V at 2A, RDDW20F-12 is ±12V at 835A, and RDDW20F-15 is ±15V at 666A.
