Frequently Asked Questions
Can I use the RS-100-3.3 for 3.3V logic, FPGA, or processor-heavy embedded hardware?
Yes, it is a constant-voltage 3.3V supply rated for 20A and 66W. That makes it relevant for embedded or digital hardware that needs a high-current 3.3V rail in an enclosed system.
Is the RS-100-3.3 suitable for industrial electronics that run on a 3.3V bus?
It can fit industrial electronics designed for 3.3V constant voltage, as long as the total draw remains within 20A and 66W. Its 88-264VAC input also supports equipment intended for a broad AC input range.
Can this model power multiple 3.3V control or communications boards in one enclosure?
It is suited to grouped 3.3V loads in a protected enclosure when the combined requirement stays within 20A and 66W. The compact 159.0 × 97.0 × 38.0 mm package helps where internal equipment space is tight.
Is the RS-100-3.3 rated for indoor or outdoor conditions?
The listed operating temperature range is -25°C to +70°C, and the features note 5G vibration resistance. No IP rating is provided, so the available specs support protected indoor industrial use rather than direct outdoor exposure.
How does the RS-100-3.3 compare with the other RS-100 models?
The provided RS-100 outputs are 66W at 3.3V 20A for RS-100-3.3, 80W at 5V 16A for RS-100-5, 102W at 12V 8.5A for RS-100-12, 105W at 15V 7A for RS-100-15, 108W at 24V 4.5A for RS-100-24, and 110.4W at 48V 2.3A for RS-100-48. RS-100-12-OB is also listed in the family, but no output power or current figures are supplied for that version.
