Frequently Asked Questions

Can I use the LPS-50-3.3 for 3.3V embedded boards, logic devices, or industrial controllers?

Yes, this is a constant voltage 3.3V supply rated for 33W and 10A. It suits 3.3V electronics and controller loads that stay within 10A total output current.

Is the LPS-50-3.3 appropriate for FPGA, MCU, or SBC power in a compact enclosure?

It can fit compact equipment because the housing is 195.0 x 55.0 x 23.0 mm and weighs 0.24 kg. The low-profile 23.0 mm design is useful where internal height is limited.

Can this model power 3.3V industrial communication or embedded I/O hardware?

It is intended for 3.3V constant voltage loads and provides up to 33W with 10A output current. That makes it suitable for 3.3V electronics in automation or embedded systems when the total load stays within those limits.

Would the LPS-50-3.3 make sense for lab or test fixtures that need regulated 3.3V DC?

It can be used for bench or fixture applications that require a fixed 3.3V output and no more than 10A. The 90-264VAC input is also useful where the AC source may vary across standard mains ranges.

Can the LPS-50-3.3 be used in hot or cold indoor equipment environments?

The specified operating temperature range is -20°C to +70°C. The provided specs do not include an IP rating, so environmental protection beyond that temperature range is not stated.

How does the LPS-50-3.3 compare with the other 3.3V LPS versions?

The listed 3.3V siblings are LPS-50-3.3 at 33W and 10A, LPS-75-3.3 at 49.5W and 15A, and LPS-100-3.3 at 66W and 20A. They share the same nominal 3.3V output, with higher models providing more wattage and current.
