Frequently Asked Questions
Can I use the HRP-450-3.3 for high-current 3.3V embedded processing boards?
Yes, this unit is a constant-voltage 3.3V supply rated for up to 90A and 297W, which suits 3.3V electronics that need very high current. It accepts 85-264VAC input, so it can be used in mains-powered lab or industrial systems.
Is the HRP-450-3.3 suitable for FPGA, logic, or communication backplane loads?
It can be appropriate for 3.3V digital loads when the system requires a fixed 3.3V rail and the total demand stays within 90A and 297W. The constant-voltage output is intended for equipment designed around a regulated 3.3V input.
Can this power supply support a 3.3V electronics burn-in or validation rack?
Yes, provided the rack needs a constant 3.3V source and its combined draw does not exceed 297W or 90A. The enclosure size is 218.0 x 105.0 x 41.0 mm, which can help in dense bench or cabinet layouts.
How does the HRP-450-3.3 compare with other 3.3V HRP models?
The listed 3.3V siblings 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, and HRP-600-3.3 at 396W and 120A. The HRP-450-3.3 sits between the 198W and 396W versions with 297W output and 90A current.
Can the HRP-450-3.3 be used in harsh environments with low or high ambient temperatures?
Its stated operating temperature range is -40°C to +70°C, which supports use across a wide thermal range. The provided specifications do not include an IP rating, so the data does not confirm outdoor, wet-location, or dust-exposed suitability.
