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 and Static characteristics for more details.
  5. 5. Without water or fan cooling to provide adequate heat dissipation, OTP might be triggered if trimming output voltage by PV signal toward upper or bottom limits of nominal voltage. Under such condition, enhanced cooling on PSU is highly recommended.
  6. 6. PV/PC function when users are not operating on PMBus. SVR functions when users are neither operation on PMBus nor using PV/PC.
  7. 7. Output will shut down after O/P voltage is below < 80% of Vset for 5 sec, re-power on to recover.
  8. 8. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 600mm*900mm metal plate with 1mm of thickness. 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)
  9. 9. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
  10. 10. The efficiency is measured at 75% load.

FAQ

Can I use the PHP-3500-48 for a high-power 48V telecom or network DC bus?

Yes, this model is suited to large 48V constant-voltage systems. It is rated at 3504W with 48V output and 73A output current, which makes it relevant for telecom, network, or industrial IT equipment built around a 48V bus.

Is the PHP-3500-48 a fit for industrial embedded compute racks or control systems that distribute 48V power?

It can be, provided the equipment is designed for a 48V constant-voltage supply. With 3504W available and 73A output current, it is sized for high-load 48V infrastructure rather than small embedded boards.

Can the PHP-3500-48 be used in large automated test systems that need adjustable output behavior?

Yes, the listed features include programmable output voltage and programmable constant current level. Combined with 3504W at 48V and 73A, that makes it suitable for heavy 48V test platforms or production equipment.

Does the PHP-3500-48 support scaling to higher total 48V power?

Yes, the series supports active current sharing up to 14000W in a 3+1 arrangement. That makes this model useful when a single 3504W 48V supply is not enough for the full system load.

Is the PHP-3500-48 intended for outdoor use or wide temperature ranges?

Its working temperature range is -30°C to +70°C measured at the baseplate, with load derating at higher temperatures according to the derating curve. The supplied specs do not give an IP rating, so direct outdoor exposure is not established and a protective enclosure should be assumed if the environment requires it.

What other output options exist in the PHP-3500 family?

The PHP-3500 series has only one other output voltage: the PHP-3500-24 at 3480W 24V 145A, alongside this PHP-3500-48 at 3504W 48V 73A. Both come as a standard PMBus version or a CAN-suffix CANBus version, and an optional cold plate (ordering no. PGG1WHS-656) is available for water cooling.
