Frequently Asked Questions
Can I use the RDDW20G-05 to generate ±5V rails from a 24V, 48V, or 72V DC bus in industrial equipment?
Yes, the key advantage of this model is its wide 18-75VAC input range paired with a constant ±5V output. That makes it suitable for embedded and automation electronics fed from higher-voltage bus systems, as long as the load stays within 20W and 2A.
Is the RDDW20G-05 a good fit for telecom, transport, or distributed control electronics that run from a wide-input power rail?
It is better aligned with those environments than the narrower-input RDDW20F version because it accepts 18-75VAC. The ±5V output and 20W rating suit lower-power logic, interface, and control sections that need regulated dual rails.
Can this converter be used in compact embedded hardware where board space and weight matter?
Yes, the converter is small at 50.8 × 25.4 × 10.2 mm and light at 0.035 kg, which helps in compact industrial and embedded designs. It is still a 20W constant-voltage model with ±5V output, so the application must match those limits.
Is the RDDW20G-05 suitable for outdoor cabinets or wide-temperature field enclosures?
The operating temperature range is -40°C to +85°C, which supports use in equipment exposed to wide ambient swings. No IP rating is listed, so the specs support installation inside a protected enclosure rather than unprotected outdoor exposure.
What are the differences between the RDDW20G-05, RDDW20G-12, and RDDW20G-15?
All RDDW20G models share 20W power, 18-75VAC 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 outputs differ by model: RDDW20G-05 is ±5V at 2A, RDDW20G-12 is ±12V at 835A, and RDDW20G-15 is ±15V at 666A.
