Frequently Asked Questions

Can I use the UHP-350-3.3 for a high-current 3.3V PLC or industrial controller rail?

Yes, this model is a constant-voltage 3.3V supply rated for up to 60A and 198W. That makes it appropriate for industrial control or automation systems that specifically require a 3.3V bus with high current capacity.

Is the UHP-350-3.3 suitable for embedded computing or FPGA hardware that runs on 3.3V?

It can fit embedded or FPGA applications when the system needs a regulated 3.3V source and the total load stays within 60A and 198W. The constant-voltage output is aligned with equipment designed around a fixed 3.3V input.

Can this power supply support a dense 3.3V industrial I/O or communications rack?

It is a practical choice for 3.3V control hardware that needs substantial current headroom, because it delivers 3.3V at up to 60A. The 198W rating makes it better suited to concentrated low-voltage loads than to systems needing higher DC bus voltages.

Is the UHP-350-3.3 suitable for indoor or outdoor equipment cabinets?

The listed operating temperature range is -30°C to +70°C, which supports demanding temperature conditions. However, no IP rating is provided in the listed specs, so outdoor suitability is not established by these specs alone.

How does the UHP-350-3.3 compare with other UHP-350 models?

Within the UHP-350 group, the listed models are UHP-350-3.3 at 198W, 3.3V, 60A; UHP-350-4.2 at 252W, 4.2V, 60A; UHP-350-5 at 300W, 5V, 60A; UHP-350-12 at 350.4W, 12V, 29.2A; UHP-350-15 at 351W, 15V, 23.4A; UHP-350-24 at 350.4W, 24V, 14.6A; UHP-350-36 at 351W, 36V, 9.75A; and UHP-350-48 at 350.4W, 48V, 7.3A. The sibling list also includes UHP-350-55, but no wattage or current figures were provided for that model here.
