Frequently Asked Questions
Can I use the RS-25-3.3 to power a 3.3V embedded controller or logic board?
Yes, if the board requires a 3.3V constant voltage supply and draws no more than 6A or 19.8W. That makes it appropriate for embedded controllers, logic assemblies, and similar 3.3V electronics within that output range.
Is the RS-25-3.3 suitable for industrial electronics built around 3.3V logic?
It is designed for 3.3V constant voltage loads and can deliver up to 6A. For industrial electronics using 3.3V logic rails with moderate current demand, it is a fit as long as the total load stays under 19.8W.
Can this power supply run a small embedded gateway, communications board, or processor platform that uses 3.3V?
It can support compact 3.3V embedded platforms if their power draw is within 6A and 19.8W. The 88-264VAC input is also useful where the equipment may be deployed across different AC mains ranges.
Is the RS-25-3.3 appropriate for compact electronics where space is limited?
The enclosure measures 78.0 x 51.0 x 28.0 mm and weighs 0.2 kg, which helps in smaller equipment layouts. It combines that compact size with a 3.3V output rated up to 6A.
Can the RS-25-3.3 be used outside or in exposed industrial areas?
The operating temperature range is listed as -20 degrees C to +70 degrees C, so the temperature specification is provided. However, no IP rating is stated, so the supplied specs do not confirm suitability for outdoor exposure, dust ingress, or washdown conditions.
How does the RS-25-3.3 compare with other RS-25 models?
The RS-25 series includes RS-25-3.3 at 19.8W, 3.3V, 6A; RS-25-5 at 25W, 5V, 5A; RS-25-12 at 25.2W, 12V, 2.1A; RS-25-15 at 25.5W, 15V, 1.7A; RS-25-24 at 26.4W, 24V, 1.1A; and RS-25-48 at 27.36W, 48V, 0.57A. This 3.3V version provides the highest current in the RS-25 group, while its total wattage is 19.8W.
