Frequently Asked Questions

Can I use the UHP-500R-4.2 for a 4.2V high-current embedded or processor power rail?

Yes, this model is a 4.2V constant voltage power supply rated for 336W and 80A. It is intended for applications that specifically require a very low voltage rail with high available current.

Is this power supply suitable for low-voltage industrial electronics that need high current?

It can be suitable where the load is designed for 4.2V constant voltage input and requires substantial current capacity. The unit provides up to 80A at 4.2V with 336W total power.

Can the UHP-500R-4.2 support a centralized 4.2V DC bus in test or automation equipment?

Yes, if the equipment is built around a 4.2V constant voltage bus and the combined demand stays within 80A and 336W. This model is more specialized than the higher-voltage versions because the output is only 4.2V.

Is this a fit for compact equipment that needs a low-profile, fanless 4.2V supply?

The listed features include slim and low profile construction, fanless design, and dimensions of 232.0 × 81.0 × 31.0 mm. That makes it relevant for compact enclosures needing a 4.2V high-current source.

Can the UHP-500R-4.2 be used in outdoor or wide-temperature environments?

Its operating temperature range is -30°C to +70°C, so the temperature specification is broad. However, no IP rating is provided in the specs, so the published data does not confirm exposed outdoor suitability.

How does the UHP-500R-4.2 differ from the other UHP-500R redundant models?

The listed UHP-500R versions are 4.2V 336W 80A, 5V 400W 80A, 12V 500.4W 41.7A, 15V 501W 33.4A, 24V 501.6W 20.9A, 36V 500.4W 13.9A, and 48V 501.6W 10.45A. The UHP-500R-4.2 is the lowest-voltage option in that group and also one of the highest-current options at 80A.
