Frequently Asked Questions
Can I use the RDDW20G-12 for ±12V rails in equipment powered from a 48V class industrial bus?
Yes, this model is intended for wide-input conversion from 18-75VAC to a constant ±12V output. That makes it relevant for industrial, telecom, or embedded systems that distribute higher input voltage and need lower-power dual 12V rails within 20W.
Is the RDDW20G-12 suitable for automation and monitoring electronics that need dual 12V output from a wide input range?
It can be a fit where the source varies across the 18-75VAC range and the end equipment needs a regulated ±12V supply. The compact 50.8 × 25.4 × 10.2 mm package also supports use in smaller control or interface assemblies.
Can this model be used in vibration-prone industrial or mobile electronics?
The listed features include 5G vibration resistance, which is useful for machine, transport, or other movement-exposed electronics. It also carries a -40°C to +85°C operating temperature rating, while remaining a 20W constant-voltage ±12V converter.
Is the RDDW20G-12 designed for exposed outdoor use?
The temperature spec of -40°C to +85°C supports demanding thermal environments. However, no IP rating is provided in the product specs, so the safer interpretation is use inside a protected cabinet or enclosure rather than direct outdoor exposure.
How does the RDDW20G-12 compare with the other RDDW20G outputs?
Across the RDDW20G family, the shared specs are 20W power, 18-75VAC input, constant-voltage operation, 50.8 × 25.4 × 10.2 mm dimensions, 0.035 kg weight, and -40°C to +85°C operating temperature. The output variants are ±5V at 2A for RDDW20G-05, ±12V at 835A for RDDW20G-12, and ±15V at 666A for RDDW20G-15.
