Frequently Asked Questions

Can I use the RSD-30G-3.3 to power 3.3V embedded boards or industrial logic circuits?

Yes, it is appropriate for 3.3V constant-voltage electronics when the total load stays within 19.8W and 6A. That makes it relevant for embedded control boards, logic sections, and other low-voltage electronics that need regulated 3.3V output.

Is this a good fit for 3.3V automation electronics powered from a 9-36VAC source?

It can be a fit when the source is within 9-36VAC and the downstream 3.3V load remains at or below 19.8W. The 6A output current is useful for low-voltage electronics that need higher current at 3.3V.

Can the RSD-30G-3.3 be used in mobile or rugged embedded equipment?

Yes, for 3.3V loads up to 19.8W and 6A, it is positioned for embedded equipment use. The specified 5G vibration resistance and -40°C to +70°C operating temperature range support more demanding equipment conditions.

Does the RSD-30G-3.3 support outdoor installation?

The temperature range is specified as -40°C to +70°C, so thermal capability is defined. However, no IP rating is listed in the provided specs, so exposed outdoor or washdown use is not confirmed here.
