Frequently Asked Questions
Can I use the HRP-75-3.3 for 3.3V embedded boards or logic-level electronics?
Yes, this supply provides constant voltage 3.3V output up to 15A and 49.5W, which fits 3.3V embedded electronics that stay within that power budget. It is better aligned with logic and board-level loads than with higher-voltage industrial field devices.
Is the HRP-75-3.3 suitable for FPGA, processor, or communications boards that run on 3.3V?
It can be suitable for boards that specifically require a regulated 3.3V source and draw no more than 15A or 49.5W. The wide 85-264VAC input also makes it usable where the AC source may vary by site.
Would the HRP-75-3.3 work for industrial control logic or interface circuits?
It can support control logic and interface circuits that use a 3.3V rail and remain within the 15A output current limit. With dimensions of 129.0 × 98.0 × 38.0 mm, it can also fit smaller equipment housings.
Can this power supply be used for 3.3V test fixtures or embedded development equipment?
Yes, it can fit 3.3V test or development equipment when the total draw stays within 49.5W and 15A. The supply also offers high efficiency up to 90% and no load power consumption below 0.5W to 0.75W.
How does the HRP-75-3.3 compare with other 3.3V models in the HRP line?
The listed 3.3V HRP models are HRP-75-3.3 at 49.5W and 15A, HRP-100-3.3 at 66W and 20A, HRP-150-3.3 at 99W and 30A, HRP-200-3.3 at 132W and 40A, HRP-300-3.3 at 198W and 60A, HRP-450-3.3 at 297W and 90A, and HRP-600-3.3 at 396W and 120A. HRP-75-3.3 is the smallest-capacity 3.3V option among those models.
Is the HRP-75-3.3 suitable for outdoor use or only indoor enclosures?
The temperature rating is -40°C to +70°C, so the operating temperature spec is broad. However, no IP rating is provided in the supplied specs, so outdoor exposure suitability cannot be confirmed from the listed data.
