Frequently Asked Questions
Can I use the HRP-100-3.3 for 3.3V embedded processors, FPGA boards, or logic-heavy controllers?
Yes, if the equipment needs a constant 3.3V rail and the total draw stays within 20A and 66W. That makes it better aligned with high-current 3.3V electronics than higher-voltage models in the same family.
Is the HRP-100-3.3 suitable for industrial control electronics that run on a 3.3V backplane?
It can be used where the control electronics are designed for constant 3.3V DC and the combined load does not exceed 66W or 20A. Buyers should match it to 3.3V-only sections of the design, not to equipment that expects 5V, 12V, 24V, 36V, or 48V.
Can this model power multiple 3.3V embedded modules from one supply?
It can, as long as the total current remains within 20A and the total power remains within 66W. The constant-voltage 3.3V output is intended for equipment that already regulates around a fixed 3.3V DC input.
Is the HRP-100-3.3 intended for outdoor use or protected indoor equipment?
The temperature rating is -40°C to +60°C, so the operating range supports harsh indoor equipment environments. No IP rating is listed in the provided specs, so outdoor or washdown suitability is not established here.
When should I choose the HRP-100-3.3 instead of a larger 3.3V HRP model?
Choose it when your 3.3V load fits within 20A and 66W. If you need more 3.3V capacity, the listed larger options are HRP-150-3.3 at 30A and 99W, HRP-200-3.3 at 40A and 132W, HRP-300-3.3 at 60A and 198W, HRP-450-3.3 at 90A and 297W, and HRP-600-3.3 at 120A and 396W.
