Test conditions and notes10
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance :includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltages. Please check the derating curve for more details.
  5. 5. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft)
  6. 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. 7. R type efficiency slightly less than the Blank type, according to the actual measurement.
  8. 8. Inrush current parameter has 10% tolerance .
  9. 9. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.
  10. 10. 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-200R-4.2 for a low-voltage, high-current embedded electronics load?

Yes, this unit is designed for constant voltage output at 4.2V and can deliver up to 40A, with a total power rating of 168W. That makes it suitable for equipment built around a 4.2V DC rail rather than higher-voltage control systems.

Is the UHP-200R-4.2 suitable for industrial test equipment that needs a regulated 4.2V supply?

It can be, provided the test equipment specifically requires 4.2V constant voltage and does not exceed 168W or 40A. The fanless design also helps in benches or enclosures where forced-air cooling is not preferred.

Can this model be used for a redundant 4.2V DC power rail?

Yes, the built-in redundant function and DC OK feature make it relevant for 4.2V systems that need monitored power status and redundancy support. Its output is limited to 4.2V, 40A, and 168W, so it should only be used on loads designed for that rail.

Does the UHP-200R-4.2 work well in tight industrial enclosures?

It is relatively compact at 194.0 × 55.0 × 26.0 mm and weighs 0.468 kg, so it is practical for low-profile equipment layouts. The slim housing and fanless construction are especially useful where enclosure space is limited.

Can the UHP-200R-4.2 be used outdoors or in harsh temperature conditions?

The published operating temperature range is -30°C to +70°C, which covers a wide temperature span. No IP rating is listed, so it should be treated as a unit for protected environments rather than direct outdoor exposure.

How does the UHP-200R-4.2 compare with the other redundant UHP-200R versions?

The redundant UHP-200R line includes UHP-200R-3.3 at 132W and 40A, UHP-200R-4.2 at 168W and 40A, UHP-200R-5 at 200W and 40A, UHP-200R-12 at 200.4W and 16.7A, UHP-200R-15 at 201W and 13.4A, UHP-200R-24 at 201.6W and 8.4A, UHP-200R-36 at 201.6W and 5.6A, and UHP-200R-48 at 201.6W and 4.2A. This version is the 4.2V member and is rated at 168W with the same 40A output current as the 3.3V and 5V high-current variants.
