Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance :includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. The ambient temperature derating of 3.5℃/1000m is needed for operating altitude greater than 2000m(6500ft)
6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies." (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
7. Please refer to derating curve.
8. R type efficiency slightly less than the Blank type, according to the actual measurement.
9. Inrush current parameter has 10% tolerance.
10. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.
11. Some models or factory may not have the BIS marking , please contact MEAN WELL’s sales for more details.

FAQ

Can I use the UHP-500-4.2 for a high-current 4.2V embedded or electronics test fixture?

Yes, this model is built for applications that need a constant 4.2V rail at high current. It delivers up to 80A with a total output power of 336W, which suits 4.2V test and embedded loads designed for that bus voltage.

Is the UHP-500-4.2 appropriate for industrial electronics that run on a 4.2V DC bus?

It can be appropriate where the equipment specifically requires constant 4.2V input. The unit provides 4.2V at up to 80A, so it is aimed at low-voltage, high-current loads rather than higher-voltage control systems.

Would this power supply work for a production burn-in rack for 4.2V boards or modules?

Yes, it is suitable for burn-in or validation setups built around a constant 4.2V supply rail. Its 336W rating, 80A output current, and fanless design make it a practical option where many 4.2V loads are grouped into one higher-current source.

Can I use this for a high-current 4.2V automation subsystem instead of a 5V or 12V supply?

Only if the subsystem is designed for a constant 4.2V input. This unit provides 4.2V and up to 80A, while the other UHP-500 variants listed use different output voltages and corresponding current ratings.

Is the UHP-500-4.2 suitable for outdoor equipment cabinets?

The provided specs list an operating temperature range of -30°C to +70°C, but they do not provide an IP rating. That means the temperature capability is defined, while outdoor dust and water exposure suitability is not established by the listed specifications.

How does the 4.2V model compare with the other UHP-500 versions?

The listed UHP-500 family includes 500.4W at 12V and 41.7A, 501W at 15V and 33.4A, 501.6W at 24V and 20.9A, 500.4W at 36V and 13.9A, 501.6W at 48V and 10.45A, 400W at 5V and 80A, and 336W at 4.2V and 80A. This model is the lowest-voltage option shown and is designed around very high current at 4.2V.
